    Representative Clients:

    • Drug Distribution Charges Dismissed for my Client and Eleven Others         My client was charged in federal court with selling heroin to a confidential ATF informant, supposedly caught on video. The same informant had been used by ATF to make cases against over a dozen people in state and federal cases. Expert analysis of the video raised doubt over whether any drug exchange took place. I developed substantial evidence that the informant had scammed the ATF agents he was working for, providing them with counterfeit drugs of his own and pocketing the drug buy money,  and was able to get away with his scam because ATF agents and prosecutors failed to adequately monitor what he was doing. This involved examination of phone records, to show that calls that the informant claimed to have had with my client never happened. It involved the examination of lab tests from all of the informant’s dozens of buys, and finding that the  lab results from drugs supposedly sold by my client were an exact match of drugs the informant claimed he was sold by another defendant days later, and that both contained such low amounts of heroin that it was essentially counterfeit. It involved the review of dozens of videos, ATF reports and lab results from the informant’s other buys, to find other occasions when videos showed no money or drugs, and recorded no conversation about a drug deal, and then seeing if those deals also involved counterfeit drugs. Ultimately, I developed compelling evidence that the informant had framed my client and others. Based on this work, the informant took the Fifth, and refused to testify at the trial of my client or anyone else. The Attorney General’s Office then dismissed eleven cases that involved the informant. The charges against my client were dismissed., 2019
    • Murder, Multiple Counts - Found Not Guilty – The Blackstone “House of Horrors” Case Responding to a call from a neighbor, police discovered two toddlers, a 5-month-old and a 3-year-old, that had been left in the care of my client’s 10-year-old son for several hours. The home was in unimaginable squalor. Upon returning home, unable to provide identification for the toddlers, my client told police that she had given birth to both children in secret in her home, that they had been raised in secret, and had never been outside of the home. Skeptical of the story, police obtained a search warrant, seeking materials that might shed light on the identity of the children. The skeletal remains of three babies, each near full-term, were discovered in closets. My defense strategy combined evidence of mental illness with a challenge to the allegations that the babies were murdered, contending that two of the babies were stillborn and the third died shortly after birth of natural causes. The trial focused heavily on expert psychiatric and forensic witnesses, with particular emphasis on challenging the Commonwealth’s witnesses on the issues of whether the infants were born alive, and whether my client did anything to cause their deaths. At trial, my client was found not guilty on all murder charges. , 2017
