Dec. 20, 2022 – Westchester County District Attorney Miriam E. Rocah announced today that a 15-year-old pled guilty to Manslaughter in the First Degree, a felony, for the April 2022 fatal stabbing of 16-year-old Kayla Green in Mount Vernon and has been promised a sentence of three to nine years in state prison. The defendant is scheduled to be sentenced on Jan. 24, 2023.

DA Rocah said: “Today, the defendant has taken responsibility for ending the life of Kayla Green and now faces consequences for this tragic and devastating incident. We hope the families of all impacted by this senseless violence can begin the journey to healing. My Office will continue to support them in any way that we can.”

On April 8, 2022, at approximately 3:55 p.m., after a school celebration turned violent, the defendant stabbed Green, a Mount Vernon High School sophomore, in the abdomen with a knife on Gramatan Avenue in Mount Vernon. The victim was transported to Jacobi Medical Center in the Bronx, where she was pronounced dead.

The Mount Vernon Police Department arrested the defendant on the evening of April 8, 2022, in Dobbs Ferry, following an investigation, with assistance from the Westchester County Department of Public Safety and the FBI’s Westchester Safe Streets Task Force.

The defendant was also charged in connection with the stabbing of another teenager at the scene of the incident. Under New York law, at the time of the defendant’s plea, those additional charges were dismissed due to the defendant’s age.

The case is before Judge Susan Cacace in Westchester County Youth Part, and is being prosecuted by Homicide Bureau Chief Lana Hochheiser and Bureau Chief James Bavero, both of the Trials and Investigations Division.
