Verdicts / Settlements (Case Results)

  • DWI - First Offense, Bexar County, CCL1: Following a traffic stop triggered by a third-party call about a minor sideswipe, the client was arrested. They reported memory gaps from a night out, consented to a blood draw, and did not recall field sobriety testing. We obtained the police reports, reviewed available video, and examined the lab paperwork. We pressed the state on the limited officer observations and their reliance on a witness report to establish impairment. With those weaknesses highlighted, we negotiated a reduction to a lesser offense.
  • DWI - Second Offense, Comal County, CC2: Police responded to a two-vehicle collision where our client was accused of rear-ending another car. Officers investigated impairment and a blood sample was taken. With a prior DWI on record, the stakes were high. We obtained the crash report and lab records, addressed interlock compliance issues, and presented mitigating facts about the client's work obligations and the passage of time since the earlier case. After persistent negotiations, the client accepted straight probation, avoiding additional jail time.
  • Terroristic Threat, Bexar County, Criminal, District Court: After a frightening driving incident, the client called the number on a commercial vehicle and left an angry voicemail criticizing the driver. Deputies later reached out about the message and came to the residence to seek a statement, which the client declined. Days after that contact, the client was arrested for felony terroristic threat tied to the voicemail and comments to officers. We obtained the recording, call logs, and reports, and showed the communication arose from a heated complaint, not a credible threat. We pressed the state on the lack of specific, imminent harm and intent. The prosecution dismissed the case.
  • DWI - Second Offense, Bexar County, CCL 14: After a night out at a couple of bars, the client was stopped by police with no crash and was arrested. The reason for the stop was unclear, and the client only remembered parts of the roadside tests. They agreed to a breath test but did not know the reported number. With prior DWI history, the stakes were high. We requested discovery and scrutinized the basis for the stop, the officer's instructions during the field tests, and the breath testing procedures. We pressed these issues with the prosecution and prepared to litigate. The state dismissed the case.
  • DWI - Third Offense, Bexar County, Criminal, District Court: We obtained discovery and scrutinized every piece of the state's proof, from the intoxication evidence to the enhancement allegations based on prior convictions. We pressed for video, calibration and certification records, and documents linking the priors to our client, and found material gaps and inconsistencies. We set the case for contested hearings and made clear we were ready for trial. With their key issues exposed and admissibility in doubt, the prosecution dismissed the case.
  • Resisting Arrest, Bexar County, CC5: The client was found asleep on a sidewalk and taken to jail, where the case was filed as resisting arrest. We obtained the arrest report and booking records, showing the contact started as a public intoxication pickup and that the client's impaired state and memory gaps made willful resistance questionable. We used those circumstances in negotiations and pushed for a more proportionate outcome. The charge was reduced to a lesser offense, and the court credited time already served, resolving the case.
  • DWI - Second Offense, Bexar County, CC4: Stopped for an expired registration sticker, the client was accused of slurred speech and asked to perform field sobriety tests. After admitting to having a couple of drinks, they refused a breath test and officers obtained a warrant for a blood draw. We secured the patrol videos, reports, and warrant documents, challenged how the roadside tests were administered and scored, and questioned aspects of the warrant process. Leveraging those issues in negotiations, we pushed back on a second-offense filing and the charges were reduced.
  • DWI - First Offense, Bexar County, CCL 15: There was a minor single-vehicle crash into a neighborhood fence, and officers arrived to investigate. The client admitted to drinking, completed field sobriety tests, was arrested, and later gave a breath sample at the jail that read 0.16. We obtained the police reports and discovery, scrutinized how the roadside testing was conducted, and noted that no roadside breath test was given. We highlighted the short window between last consumption and the station test and challenged proof of impairment at the time of driving. The state dismissed the case.
  • DWI - Second Offense, Bexar County, CC15: The client was arrested after a traffic stop and charged with a second DWI. She provided a breath sample and, due to severe shaking, was taken for medical evaluation. We shifted the focus to rehabilitation, compiling proof of intensive treatment, sober living, consistent meeting attendance, and volunteer work. We engaged the prosecutor and prepared the client to address the court with sincere remorse and a concrete recovery plan. The state reduced the case to a lesser misdemeanor with credit for time served, avoiding probation.
  • Felony Motion to Revoke Probation, Bexar County, 187TH District Court: The client had been on long-term felony probation when supervision filed to revoke after a meeting where a pipe was seen and over issues paying for an ankle monitor. We gathered the supervision file, UA results showing clean tests, and communications with the new officer to document the client's overall compliance and the financial hardship. We engaged the prosecutor and argued the violations were nonviolent and addressable. After negotiations and a proposed compliance plan, the state backed off revocation. The client remained on probation.
  • DWI - First Offense, Bexar County, CC 2: After a minor collision with a parked, unoccupied car, officers initiated a DWI investigation. The client admitted to drinking, completed field sobriety tests, and recalled stumbling, which we argued was consistent with post-crash stress and an airbag deployment. They refused a roadside breath test, and a blood sample was later taken at the jail. We reviewed the police and crash reports, emphasized the absence of injuries, and challenged the weight of the roadside exercises. The case resolved with deferred probation.
  • DWI - Second Offense, Bexar County, CC 11: Stopped for alleged weaving after leaving a gathering, the client performed roadside tests after warning the officer about chronic knee issues. The officer indicated the client did fine, yet arrested anyway. A breath sample was taken even though no written consent was signed, and another officer offhandedly said the machine reads high before calling it a joke. We scrutinized the reports, the officer’s instructions, and the breath testing paperwork, challenged the field tests given the knee condition and mixed messages, and questioned the breath test’s reliability and consent. The case was reduced and resolved with deferred probation.
  • Assault by Contact (Class C), Bexar County, SAMC Court 7: After receiving a mailed citation for Class C assault stemming from an encounter during a massage, the client contacted us before the first setting. We obtained the report, which relied largely on the complainant’s statement that he made offensive contact, and engaged the prosecutor about the evidentiary gaps. Rather than risk a conviction, we negotiated deferred probation with informal conditions, including completion of classes and a no-contact term, keeping a conviction off the client’s record.
  • DWI - First Offense, Bexar County, CCL9: The client was stopped for speeding after leaving a social outing and admitted to having drinks. Officers conducted field sobriety tests, arrested the client, read warnings, and obtained consent for a blood draw. Our team reviewed the reports and evidence, and documented the client's longstanding balance issues and prescribed medication that can affect performance on roadside tests. We emphasized the lack of prior record and the limited driving behavior that led to the stop. Using those weaknesses, we negotiated with the prosecutor to reduce the charge.
  • DWI - First Offense, Bexar County, County Court-at-Law 5: After a crash at an intersection, the client called for help and was investigated for DWI. Officers said they observed intoxication, located beer in the vehicle, and conducted only limited field sobriety testing even though the airbags had deployed. A breath test was taken. We pulled the video and crash records and documented the client’s injuries and post-collision disorientation, which undercut reasonable suspicion for the tests and the arrest. Confronted with those problems, the prosecutor agreed to reduce the charge to a lower-level DWI.
  • Evading arrest in a vehicle, The individual was arrested for evading arrest with a vehicle after failing to stop for police due to outstanding tickets. Reckless driving charges followed for speeding. Additional citations were issued for speeding and driving with an expired registration.
  • DWI 2nd, The individual was arrested after a car accident during which another driver ran a red light. The client refused a preliminary breath test and was taken in for a blood test. Field tests were declined due to concerns about head trauma and adrenaline affecting performance.
  • Assault FV - Class C, The client took a friend and the friend's mom out for a birthday. On the way home, the friend's mom assaulted the client while driving. The client left her on the side of the road, and a bystander called the police. The client admitted to driving and took field sobriety tests, but said the terrain was sloped. Client took a blood test. Additionally, a handgun was found in the car door.
  • POCS felony, The client was arrested after being stopped for a headlight issue. Marijuana and a THC pen were found. The client was charged with possession of a controlled substance. The client had no prior convictions.
  • Assault on a Pregnant Person, The individual was arrested for violating bond/protective order after being found with their spouse during a traffic stop. Initial charges involved the alleged assault of the pregnant spouse. The spouse did not want to press charges.
  • Terroristic threat, The Individual was arrested for leaving a threatening voicemail to a bus company after a road incident and was charged with making a terroristic threat.
  • Reckless driving, The client was arrested for evading arrest with a vehicle after failing to stop for police due to outstanding tickets. The individual was charged with reckless driving for speeding in a 35 mph zone. The client was also cited for speeding and expired registration.
  • DWI 3rd, The client was arrested for suspected DWI after being found asleep at a gas station. The police were alerted to his presence by the fire department. Blood was drawn to determine BAC. The client also had prior DWI offenses.
  • Deadly Conduct Felony, The individual was arrested after experiencing a mental health crisis, during which voices urged the use of a firearm. Family members were concerned about mental health and firearm restrictions.
  • Possession of a Controlled Substance (Felony), Bexar County, Pre-indictment Court DC: Stopped for failing to maintain a single lane, the client opened the console for insurance and an officer spotted a disposable vape. A roadside test allegedly showed THC, the client was arrested, and a search found two more nearly burnt pens. We moved quickly, challenging the basis for the stop, the plain view seizure, and the reliability of the field test. We also questioned whether the trace residue and circumstances actually tied the pens to our client. Confronted with these issues before indictment, the state dismissed the case.
  • Possession of a Controlled Substance (Felony), Bexar County, 175TH DC: Police investigated an earlier incident and obtained the client's consent to search a vehicle for weapons, then reported finding a felony amount of contraband. We scrutinized how the search expanded beyond the stated consent and dissected the reports and chain of custody. Our team gathered mitigation, including the client’s lack of prior record and corroborating background materials. We pressed these issues in negotiations with the prosecutor. The case resolved with a plea to straight probation.
  • DWI - First Offense, Comal County, CC 1: Police stopped our client for alleged weaving and an improper stop at a light. He had roughly two to three drinks over several hours at a local brewery before the stop. Field sobriety tests were done on a cold night while he was visibly shaking, and he reported anxiety and blood pressure medications. He agreed to a breath test, was not given a number at the scene, and later received a license suspension notice. We challenged the basis for the stop and the testing conditions, highlighted medical factors, and negotiated deferred probation to avoid a conviction.
  • Assault by Contact (Class C), Bexar County, Precinct 2, Place 1: During a hospital visit for a family medical emergency, a dispute with our client’s former partner’s companion escalated and officers were called. The client acknowledged physical contact and later received a Class C assault citation by mail. We stepped in, gathered the client’s photos, videos, and messages documenting prior unwanted contact by the complainant, and confirmed a clean criminal history. We presented that context and the client’s cooperation to the prosecutor, pressing for a constructive resolution. The case was resolved with deferred probation.
  • DWI - First Offense, Bexar County, County Court-at-Law 11: After a minor fender bender, our client exchanged insurance information and waited for police. Officers questioned the client about prescription medications, requested sobriety tests, and the client declined. The client consented to a vehicle search, which turned up nothing illegal and only a cup of water. The state relied on officer observations rather than a breath result. We obtained the videos and reports, underscored the minimal damage, clean search, medication issues, and lack of standardized testing. Faced with those weaknesses, the prosecutor agreed to reduce the charge.
  • DWI - Second Offense, Atascosa County, County Court at Law: After a traffic stop for swerving when reaching for a dropped phone, the client admitted to drinking and officers noted an open container. No field sobriety tests were performed, there was no roadside breath test, and a blood draw was later taken by warrant. We focused on the weak roadside investigation, the validity of the warrant process, and whether required warnings were given. With a prior DWI already on record, we pressed these issues in negotiations. The case resolved with straight probation, sparing the client additional jail time.
  • DWI (BAC Over .15), Medina County, County Court at Law: The client was stopped for speeding and arrested after field sobriety tests. At the station, two breath samples came back at .165 and .181, and officers also obtained a blood sample. We reviewed the dashcam alongside the report, noting confusing instructions during the tests and inconsistencies in the narrative. We also challenged the reliability of the breath results given the variance between samples and raised concerns about how statutory warnings and requests were delivered. Leveraging these issues in negotiations, the prosecution agreed to reduce the charge.
  • Sexual Assault, Bexar County, DC175: During a contentious child support dispute, our client was arrested after a scheduled child exchange and accused of sexual assault tied to a past relationship. We obtained CPS and law enforcement records, lined up the timeline with family-court filings, and identified credibility issues and a strong motive behind the complaint. We compiled inconsistencies between initial reports and later statements and put that in front of the prosecutor. After sustained negotiations, the state agreed to reduce the charge and we secured deferred probation.
  • DWI - First Offense, Gillespie County, CCL: After a dispute over a bar tab, staff called police. The client had already pulled over when officers arrived, performed field sobriety tests, and later provided a breath sample under .15. We obtained the reports and any video, scrutinized how the tests were given, and emphasized her clean history and cooperation. We also lined up alcohol education and an evaluation to reduce conditions and pursue an interlock waiver. The prosecution agreed to deferred probation, preserving the chance to keep a conviction off her record.
  • Possession of THC (State Jail Felony), Bexar County, Pre-indictment District Court: Police approached the client at a closed park and, after seeing smoke and claiming an odor of marijuana, searched a backpack and reported finding marijuana along with a THC concentrate. The case remained in a pre-indictment posture while the state sought lab testing. We obtained the discovery, scrutinized the stop and search, and pressed the prosecution on the lab's ability to reliably identify and weigh the concentrate. We made clear we were prepared to litigate suppression and to attack any gaps in the chain of proof. Confronted with those evidentiary issues, the state dismissed the case.
  • Harassment (Class B Misdemeanor), Bexar County, None: The client was investigated for harassment after sending texts and posting on social media accusing a family member of harming a child. We stepped in early, handled communications with the investigator, and compiled the texts, call history, and surrounding context showing there were no threats and that the statements related to reporting suspected abuse. We challenged the evidentiary basis and confirmed the complainants did not wish to proceed. The investigator marked the case unfounded, and it was dismissed.
  • DWI - Third Offense, Medina County, 454TH DC: A deputy stopped our client after claiming a backseat passenger was not wearing a seat belt. There was no crash or injury. The client admitted drinking and a breath test reportedly came back just over the limit. We dug into the legality of the stop and the breath testing procedures, and compiled a strong mitigation package showing months of alcohol monitoring, consistent AA attendance, and clean tests. Leveraging those issues and his sustained compliance, we negotiated felony probation with a structured treatment component instead of prison.
  • Public Intoxication, Kendall County, Boerne Municipal Court: Officers responded to a welfare call and found our client asleep outside a business after drinking. He was not driving, had been dropped off by a companion, and had recently started a prescription that intensified the effects of alcohol. We compiled those facts, emphasized the non-driving, welfare-check context, and questioned whether the situation showed a danger to the public. After sustained discussions with the prosecutor, the state declined to proceed and the case was dismissed.
  • Accident Involving Injury, Bexar County, 187TH District Court: After a rear-end collision, the client parked nearby, briefly walked away, then returned as first responders arrived. The other driver later reported back pain and EMS responded. Prosecutors pursued a felony accident involving injury, alleging he failed to remain. We obtained the crash report and EMS records and emphasized that he returned, that his account referenced a memory lapse, and that the evidence did not clearly establish intent. After sustained negotiations, the state reduced the charge and he received deferred probation, avoiding a felony conviction.
  • Felony Motion to Revoke Probation, Bexar County, 175TH DC: While on felony community supervision, the client was hit with a motion to revoke after missed reporting months and a new resisting arrest allegation that followed a traffic stop. We stepped in immediately, contacted probation, and pushed to avoid a second arrest warrant while the alleged violations were consolidated. Our team requested body-worn camera and other records from the arrest and challenged the basis for the new allegation. We also documented the client’s recent efforts to get back into compliance. After negotiations with probation and the DA, revocation was set aside and the case resolved with deferred probation.
  • DWI - First Offense, Bexar County, CC 12: After a minor collision, our client was arrested for a first DWI with a reported blood alcohol level over .15. We gathered insurance documentation and confirmation from the state that no restitution was owed, removing a key obstacle to leniency. We also compiled months of spotless pretrial compliance and proof of proactive treatment and lifestyle changes. Keeping negotiations focused with the prosecutor and their supervisor, we pressed for relief. The state agreed to remove the enhancement and reduce the charge.
  • Driving While License Invalid, Bexar County, CC 9: The client was stopped during a traffic patrol and cited for driving while license invalid. We obtained the officer’s report and the driving record, then mapped a timeline of the alleged suspension. The documentation did not match the date of the stop, and the state’s proof of notice and status was incomplete. We made clear we would challenge those elements and the admissibility of the evidence. Facing significant proof issues, the prosecution dismissed the case.
  • DWI - First Offense, Guadalupe County, CC2: Officers responded to a single-vehicle crash where airbags deployed. The client was taken to a hospital and a blood sample was drawn. We obtained the accident report and medical records to lock down the timing and handling of the sample. We compared the officer narrative to the documentation and raised questions tying alleged impairment to actual driving. After sustained negotiations, the state accepted a reduction to a lesser charge.
  • Solicitation of Prostitution, Guadalupe County, CC 2: After a sting operation, the client was arrested for solicitation of prostitution when a video and name surfaced online. We obtained discovery, reviewed the arrest report and available footage, and closely examined how the contact and arrest were documented. We raised concerns about the operation's procedures and the online exposure, then pushed those points in negotiations. The state ultimately agreed to deferred probation, allowing the client to avoid a final conviction upon successful completion.
  • DWI - Second Offense, Bexar County, CC9: Our client was stopped after speeding and striking traffic cones near a crowded venue area. Officers reported signs of intoxication, and the client acknowledged drinking. They refused field sobriety tests and a breath sample, so police obtained a blood warrant. With a prior DWI on record, the stakes were high. We scrutinized the stop, the warrant, and the blood draw procedures, emphasizing the lack of roadside testing data and presenting mitigation. The case was resolved with straight probation.
  • DWI - First Offense, Bexar County, County Court-at-Law 5, After a late-night traffic stop for allegedly cutting off another driver, officers noted an odor of alcohol and had our client perform roadside tests. The client declined a breath test and a warrant was obtained for a blood draw. We reviewed discovery, scrutinized the basis for the stop and the testing, and kept pressure on the state in negotiations. The client completed alcohol education and a victim impact panel and provided proof of ongoing treatment, which we submitted in mitigation. With that record, we secured a reduction of the charge.
  • Unlawful Restraint, Guadalupe County, None: Police arrested our client after a domestic argument at a residence, alleging the client prevented the other person from leaving. We got involved early, obtained and reviewed the police report, and addressed the no-contact restrictions. The complaining witness later submitted an affidavit of non-prosecution, which we presented to the State along with context that undercut the restraint allegation. We engaged the assigned prosecutor, highlighted evidentiary weaknesses, and made clear we were prepared to litigate. The State dismissed the case.
  • DWI - First Offense, Comal County, CC 1: Officers conducted field sobriety tests and obtained a breath sample that reportedly read 0.18 before arresting our client for a first-time DWI. We secured the police reports and discovery, then reviewed the testing records to evaluate reliability and how instructions and observations were documented. We also addressed communication issues with supervision so the file reflected the client’s compliance. Despite the elevated reading, we pushed for a measured first-offense resolution. The state reduced the charge and agreed to deferred terms that kept a conviction off the record.
  • Continuous Family Violence, Guadalupe County, None: Police were called after a domestic argument at a residence. Officers arrested our client for continuous family violence based almost entirely on the complainant’s initial statement, and an emergency protective order kept them apart. We moved quickly to collect the reports, document discrepancies in the complainant’s later account, and submit an affidavit of non-prosecution. We presented the credibility issues and lack of corroboration to the prosecutor. The state dismissed the case.
  • Unlawful Carrying of a Weapon, Bexar County, 175th District Court: The client was accused of Unlawful Carrying of a Weapon after an airport checkpoint found a pistol in a backpack the client forgot was inside. A later warrant led to an out-of-state arrest, and we stepped in as counsel and demanded full discovery. We gathered records from the airport incident, confirmed lawful ownership of the firearm, and emphasized there was no intent to carry it where prohibited. We detailed evidentiary weaknesses and made clear we were prepared to litigate any search and seizure issues. The state dismissed the case.
  • Violation of a Protective Order, Bexar County, CC 13: During a traffic stop, the client was found riding with the protected person despite a no contact order from an earlier incident. Officers arrested for violating the order based on their presence together, and no new threats or injuries were alleged. We obtained an affidavit of non-prosecution from the protected person and documented that the contact was voluntary. We pressed the state that incarceration was unnecessary and a conviction would be disproportionate. The case resolved with deferred probation.
  • Driving With a Suspended License, Atascosa County, County Court at Law: The client was accused of driving with a suspended license after a minor traffic incident. He had already resolved a citation from the same event and was told there would be no further action, only to see a warrant issued later. We obtained his driving record and suspension history and confirmed the alleged suspension began after the stop, with no proof he had been notified. We compiled the records, highlighted the timeline problems, and pressed the prosecution. The state dismissed the case.
  • Unlawful Carrying of a Weapon, Bexar County, County Court-at-Law 6: A traffic stop for a minor alleged violation led officers to claim an odor of contraband, remove our client from the car, and search the vehicle, where they found a handgun. We reviewed the stop footage and police reports, then challenged the legality of the stop, the prolonged detention, and the claimed basis for the search. We also underscored that the weapon allegation hinged on proving separate unlawful conduct that the state could not reliably establish. Confronted with these problems and a looming suppression fight, the prosecution dismissed the case.
  • DWI - Second Offense, Comal County, CC2: After a late-night drive home, our client was stopped by an officer who had been lying in wait outside a residential area, then followed for several miles before the stop. Dash and body camera footage showed a prolonged tail and field sobriety tests conducted on loose gravel with unclear instructions. The officer also referenced an unrelated investigation during the initial contact. We obtained the blood-warrant packet and scrutinized the draw procedure and chain of custody. Leveraging these issues, we negotiated straight probation and avoided harsher penalties.
  • Possession of a Controlled Substance (Felony), Comal County, 466th DC: During a parking lot contact, officers approached a parked vehicle and reported finding a THC vape cartridge, which led to a felony possession charge. We obtained the reports and available recordings to map the timeline of the encounter and how the item was discovered. We challenged the legal basis for the search and the handling of the cartridge. We demanded full lab documentation on substance identity, weight, and chain of custody. Facing a suppression fight and proof gaps, the state dismissed the case.
  • DWI - First Offense, Comal County, County Court at Law 3: After a stop for driving well below the posted speed, the client was investigated for DWI. They performed field sobriety tests, initially declined a blood draw, then provided a breath sample around 0.15, and made several admissions on video. We obtained the footage and reports, challenged aspects of the stop and testing process, and highlighted key mitigation like a clean record and prompt enrollment in alcohol education. Leveraging these points, we negotiated the case down and secured a reduced charge.
  • Burglary of a Habitation, Bandera County, 198TH DC: Police linked our client to a late night entry into a private property after an earlier encounter, later finding miscellaneous items in the vehicle. The client had been off prescribed medication, was in crisis over a family matter, and had little memory of the events. We gathered treatment records, documented years of sobriety, and showed immediate willingness to pay restitution. We highlighted the lack of purposeful planning and the client's cooperation after contact. After sustained negotiations, the prosecution agreed to deferred probation.
  • Harassment, Bexar County, County Court-at-Law 5: The client was arrested after a dispute at a campground where he admitted making a rude comment about a manager and was accused of following the manager’s spouse. He denied any stalking, and the arrest relied mainly on brief encounters and a few witness statements. We secured the police report, compared the accounts line by line, and challenged whether the statutory elements of harassment were satisfied. We engaged the prosecutor early, emphasized the lack of probable cause and credibility issues, and made clear we were prepared to litigate. The state dismissed the case in full.
  • Possession of Marijuana, Kendall County, 451st District Court: During a traffic stop, our client was a passenger when officers said they smelled marijuana and conducted a probable cause search. The client was detained in a patrol car and made no admissions. Officers reported finding marijuana on the vehicle floor, not on the client. We scrutinized the basis of the stop and detention, and highlighted constructive possession issues given the passenger status and lack of admissions. Leveraging those concerns, we secured pretrial diversion.
  • Misdemeanor Motion to Revoke Probation, Bexar County, County Court-at-Law 14: The client was on deferred probation for a misdemeanor DWI when a motion to revoke was filed alleging travel outside the county, missed portable breath tests, and a diluted or positive alcohol screen. A warrant issued. We stepped in, coordinated with probation and the prosecutor, and arranged a controlled court appearance to avoid a jail booking. We negotiated a short probation extension with strict testing and documented compliance. After the client completed those terms, the state withdrew the allegations and the motion was dismissed.
  • DWI with Child Under 15, Bexar County, Pre-indictment District Court: After a late-night traffic stop with a child in the vehicle, the client was arrested for DWI with child. He performed field sobriety tests and later provided two breath samples at the station, both below the legal limit. We obtained body and dash camera footage and the breath-test records, and scrutinized the stop and test administration. The videos showed cooperative performance and no clear basis for impairment. We pressed the lack of proof of intoxication at the time of driving in pre-indictment talks. The prosecution dismissed the case.
  • Misdemeanor Motion to Revoke Probation, Bexar County, County Court-at-Law 14: The client was on deferred probation for a misdemeanor DWI when a motion to revoke was filed alleging travel outside the county, missed portable breath tests, and a diluted or positive alcohol screen. A warrant issued. We stepped in, coordinated with probation and the prosecutor, and arranged a controlled court appearance to avoid a jail booking. We negotiated a short probation extension with strict testing and documented compliance. After the client completed those terms, the state withdrew the allegations and the motion was dismissed.
  • DWI - First Offense, Bexar County, CC 11: Police stopped our client for alleged erratic driving and arrested them for DWI. They admitted to drinking, attempted roadside tests despite an old Achilles injury and knee issues, and later gave a breath sample over .15. We dug into the videos and reports, highlighting how those medical limitations affected balance and pressing the state on missing roadside body-cam. The client completed alcohol education up front. Using that leverage, we negotiated a reduction to a lower charge with deferred probation.
  • Accident Involving Damage to Vehicle Over $200, Bexar County, County Court-at-Law 9: The client was accused of leaving the scene after a minor crash and faced a charge for accident involving damage over $200. From the start they insisted nothing happened and pointed to preexisting bumper damage. We obtained the police video and reports, which showed the complainant could not initially identify a driver and later offered a different description after prompting. We also presented insurance correspondence denying the claim and photos showing the damage did not match. Confronted with weak identification and no corroboration, the prosecutor dismissed the case.
  • DWI - First Offense, Comal County, County Court at Law 3: Our client was stopped late at night after an officer claimed erratic driving and was arrested for a first offense DWI with a breath test reported over .15. The client had just finished drinking, performed roadside tests in platform shoes, and also reported poor vision. We obtained the videos and reports, challenged the vague basis for the stop, dissected the instructions and scoring on the field tests, and scrutinized the timing and procedures behind the breath test. The pressure worked, and the prosecution reduced the charge.
  • Theft (State Jail Felony), Medina County, 454th Judicial District Court: Our client was accused of felony theft stemming from prior employment at a financial services office, where several customers later claimed they paid extra cash fees not reflected on receipts. We obtained business records, till summaries, and prior audits showing the accounts balanced and the charges matched the receipts. The case file consisted only of statements, with no corroborating receipts or video for the alleged cash payments. We highlighted discrepancies and how complaints were developed through management outreach, undercutting reliability. Confronted with these proof problems, the state dismissed the case.
  • Interference with Emergency Call, Medina County, County Court at Law: Police alleged our client interfered with a 911 call during a household argument after a phone was briefly taken from the caller. We dug into the reports, call logs, and recordings to see what actually happened. The materials did not show that a call was prevented or that our client acted with the intent the statute requires. We compiled those gaps, along with context from the scene, and presented them to the prosecutor. Faced with a weak evidentiary record and a contested account, the state dismissed the interference case.
  • Assault - Family Violence, Medina County, County Court at Law: The charge arose from a domestic argument at a residence. When a door was pushed open, a family member behind it fell and suffered a minor bump, which officers treated as intentional assault. We gathered counseling records and CPS documentation showing the family had already addressed the incident and CPS closed its file, and secured statements describing the contact as accidental. We also highlighted errors in the paperwork and inconsistencies in the reports. Confronted with these issues, the prosecution dismissed the case.
  • DWI - First Offense, Atascosa County, CCL: Following a traffic stop, the client performed field sobriety tests, blew on a roadside device, and later provided a breath sample at the jail. Our team quickly obtained the dashcam video, police reports, and breath test records. We reviewed the HGN, walk-and-turn, and one-leg stand administration, and scrutinized the breath testing paperwork for procedural issues. Leveraging our workup and mitigation about the client's future goals, we pressed for a resolution that avoided a conviction. The state agreed to pre-trial diversion.
  • DWI (BAC Over .15), Bexar County, County Court-at-Law 1: After a crash with a commercial truck following a holiday gathering, the client was investigated for DWI. Officers had the driver move the vehicle to a nearby lot, conducted limited field tests, then obtained a breath sample over .15. We pulled every video and maintenance record, and highlighted the contradiction between allowing driving and claiming extreme impairment. With no prior history and proactive class completion, we pressed the state. The prosecutor agreed to drop the .15 enhancement and reduce the case to a lower DWI with deferred probation.
  • Unlawful Carrying of a Weapon, Bexar County, County Court-at-Law 12: A traffic stop for a lane change without signaling led officers to question our client. The client immediately told the officer there was an unloaded pistol secured in the center console. After an intoxication investigation, police added an unlawful carrying allegation. Our team obtained the videos and reports, scrutinized the basis for the stop, the timing and manner of the firearm's discovery, and whether the facts satisfied each element of UCW. We emphasized the voluntary disclosure and evidentiary gaps. The state dismissed the case.
  • DWI - First Offense, Bexar County, CCL12: Stopped for an alleged lane change without signaling, the client performed field sobriety tests in a parking lot and later provided two breath samples around 0.11. We secured the video and breath-test records, highlighting that the eye test was repeated several times and the report described the movement as almost unsafe. We pressed the state on reasonable suspicion, NHTSA compliance, and breath-machine procedures. Using the client’s cooperation and clean history, we leveraged these issues to secure a reduction to a lesser, non-DWI offense.
  • Possession of Marijuana, Medina County, County Court at Law: Stopped for speeding, the officer claimed an odor of marijuana, had the door opened, and searched without asking for consent. A small leftover pre-roll was found, which the client had purchased over the counter as a legal hemp product. No arrest was made at the scene, but a misdemeanor case was later filed. We obtained the video, police reports, and lab paperwork, then challenged the search and the state’s inability to prove an illegal THC concentration. After we pressed these evidentiary and suppression issues, the prosecution dismissed the case.
  • Assault on a Pregnant Person, Bexar County, Pre-indictment District Court: Officers responded to a domestic incident where someone squirted water and a fight followed. The client was labeled the aggressor and arrested. We got involved early, obtained the police reports, and spoke with witnesses to document the size disparity, that the other person delivered most of the blows, and that our client was calling for help. We challenged the primary aggressor determination and the lack of corroboration, noting the complainant did not wish to pursue. The state agreed the evidence was insufficient and dismissed the case.
