Attorney Stefanie A. Murphy is a Partner at Marin & Murphy Law Firm and one of Rhode Island's most recognized criminal defense attorneys — with 20 years of experience, 2,500+ DUI cases defended, and 14 consecutive years of Super Lawyers recognition. In October 2023, she secured a complete NOT GUILTY verdict in State v. Derek Winslow, a high-profile Providence Superior Court murder trial where her client faced charges alongside two co-conspirators who were already serving life sentences. She is the editor and contributing author of "A Practical Guide to Trying DUI Cases in Rhode Island" (MCLE, 2024) — the definitive DUI defense guide used by attorneys across New England. Throughout her career, Attorney Murphy has also served as a town solicitor — handling criminal prosecution on behalf of Rhode Island municipalities — giving her the same prosecution-side perspective that defines this firm's approach to every case.
Attorney Stefanie A. Murphy built her career with a conviction shared by her partner Matthew Marin: that the most effective criminal defense requires understanding the system from every angle. From her first year of practice, she handled the full range of state and federal criminal matters — DUI, domestic violence, violent crimes, drug offenses, and federal cases — developing the trial-level instincts and constitutional sophistication she brings to every client today. Throughout her career, she has also served as a town solicitor for Rhode Island municipalities, handling criminal prosecution on behalf of local governments alongside her defense practice. That dual experience — prosecuting and defending — gives her the prosecution-side perspective that defines this firm's strategic advantage in every case.
Over 20 years, Attorney Murphy has defended more than 2,500 DUI and criminal cases across every Rhode Island court — from first-offense DUI at District Court to Superior Court murder trials to federal proceedings in U.S. District Court. Her practice spans DUI defense, violent crimes, domestic violence, drug offenses, sexual assault, and federal criminal matters. She handles cases through every stage: from the first phone call after an arrest through motion practice, evidentiary hearings, jury trial, and appeal.
Attorney Murphy has been regularly quoted by the Providence Journal and Rhode Island Lawyers Weekly on DUI law, constitutional criminal procedure, DNA post-conviction litigation, and high-profile criminal cases — demonstrating the depth of recognition she has earned across Rhode Island's legal and press communities. In October 2023, the Providence Journal reported her complete NOT GUILTY verdict in the Derek Winslow murder trial — a case where her client's alleged co-conspirators were already serving life sentences.
Her commitment to justice extends to cases that most attorneys decline. She has fought for post-conviction DNA exoneration for a man imprisoned for nearly 40 years, challenged suppression of evidence obtained through unlawful police conduct, and taken complex criminal matters through jury trial when pleading was not in her client's interest.
Attorney Murphy's case record spans murder acquittals to DNA post-conviction exoneration efforts — representing clients where the stakes are highest.
Super Lawyers is a peer-nomination and independent research process through Thomson Reuters — fewer than 5% of attorneys in any state receive the designation. Attorney Murphy has been selected every year since 2012: first through the Rising Star designation for attorneys under 40 or within their first 10 years of practice, then through full Super Lawyers selection from 2019 forward. Fourteen consecutive years of recognition reflects sustained peer acknowledgment throughout an entire career.
