Manhattan District Attorney Alvin L. Bragg, Jr., announced the sentencing of Mitchaux Booker in connection with the death of his teenage cousin, Jallen McConnie. The case, which lasted over four years, concluded on October 29, 2025, when Booker, 37, pleaded guilty to First-Degree Manslaughter in New York State Supreme Court. He was sentenced to 18 years in state prison, according to the Manhattan District Attorney's Office.
Booker’s conviction marks the conclusion of the prosecutions related to McConnie’s death. Johnette Booker, Mitchaux’s sister and McConnie’s caregiver, was sentenced to 20 years following her conviction at a jury trial in March 2025. Joevon McConnie, a cousin, received a three-year sentence in June 2024 after pleading guilty to Second-Degree Assault. District Attorney Bragg stated that the case involved prolonged physical and emotional abuse of a child, and that Booker’s actions, including delaying medical care and providing false information to authorities, contributed to McConnie’s death.
The case involved extensive work by Assistant District Attorneys Nicole Blumberg and Thomas Kendris, and Major Case Analyst Desiree Marks, with oversight from Assistant District Attorney Christopher Prevost and Executive Assistant District Attorney Lisa DelPizzo. Additional support was provided by Shelby Whalen from the Special Victims Bureau and other members from various bureaus. The NYPD, including Detective Paul Scott from the 24th Precinct, and FDNY Captain Peter Kearney, also contributed to the investigation. These combined efforts contributed to the conviction in the case of Jallen McConnie.
The Survivor Services Bureau provided support throughout the case, with counselors including Nakeisha Vanterpool and Sierrah Smalls assisting those affected. With the final sentence now issued, officials reiterated the importance of accountability in response to Jallen McConnie’s death.
