Manhattan District Attorney Alvin L. Bragg, Jr., today announced that NAQUAN ANDERSON, 28, TREVOR CARPENTER, 44, and ALVIN NELSON, 45, were each sentenced to 22 years-to-life in state prison for the fatal stabbing and assault of 33-year-old Jervey Barfield in Upper Manhattan on May 3, 2025. On August 11, 2026, a New York State Supreme Court jury convicted ANDERSON and NELSON of Murder in the Second Degree and CARPENTER of Manslaughter in the First Degree. All the defendants were also convicted of Gang Assault in the First Degree.
“The defendants caused a personal dispute to spiral into deadly violence when they brutally attacked Jervey Barfield,” said District Attorney Bragg. “Mr. Barfield was unarmed when the defendants repeatedly stabbed and beat him, leaving him helpless on a Manhattan sidewalk. These sentences hold all three defendants accountable for their actions, and I hope they provide a sense of justice for Mr. Barfield’s family and loved ones, who continue to endure the unimaginable pain of their loss.”
As proven at trial, on May 3, 2025, prior to the stabbing, NELSON argued with and physically fought Mr. Barfield over a personal dispute outside a deli, near West 142nd Street and Frederick Douglass Boulevard. NELSON was then joined by CARPENTER and ANDERSON, and the defendants walked down the block, pursuing Mr. Barfield.
At approximately 5:14 a.m., the defendants confronted Mr. Barfield, near West 141st Street and Frederick Douglass Boulevard, where a second physical altercation ensued. During the attack, NELSON and ANDERSON stabbed Mr. Barfield several times, including in the face, neck, and torso, while CARPENTER simultaneously assaulted him. Once Mr. Barfield collapsed on the ground, immobile, CARPENTER continued punching him in the back of the head.
Following the attack, the defendants ran back up the block. NELSON and ANDERSON stopped at the deli, where they used a bottle of water to wash blood from their hands and arms. All of the defendants then entered CARPENTER’s car, which was parked nearby, and fled toward the 145th Street Bridge.
Mr. Barfield was transported to a hospital, where he died from stab wounds to his neck and torso, as well as blunt force injuries to his head.
NELSON was arrested on May 16, 2025. CARPENTER was arrested on May 22, 2025. ANDERSON was arrested on June 9, 2025.
Assistant D.A.s Kathleen Coulson and Madison Meyer handled the prosecution of the case under the supervision of Assistant D.A. Nicole Blumberg (Chief of Trial Bureau 40) and Executive Assistant D.A. Lisa DelPizzo (Chief of the Trial Division). Trial Preparation Assistants Robert Rose and Catalina Rojas, Senior Investigative Analyst Anissa Weisel, and Senior Investigator Dennis Suarez provided invaluable assistance in the prosecution.
