July 15, 2022 – Westchester County District Attorney Miriam E. Rocah announced on July 15, 2022, that former Mount Vernon Police Officer Antoine Henrys was sentenced to three months in jail and five years of probation for a collision he caused by driving in excess of 120 miles per hour, while off duty, on the Hutchinson River Parkway that resulted in the death of 52-year-old White Plains resident John Osario.

“Our hearts go out to the victim’s family,” DA Rocah said. “We are disappointed that the Court did not agree with our recommendation that a sentence of state prison be imposed to hold the defendant accountable for causing the victim’s death by his unquestionably dangerous driving.”

On Sept. 25, 2020, at approximately 9:27 p.m., Henrys, 39, of Mount Vernon, was speeding northbound on the Hutchinson River Parkway near Lincoln Avenue in Mount Vernon. He struck the rear of a vehicle, which caused the driver to lose control and hit the motorcycle Osario was driving. The impact resulted in the victim’s body being thrown into the southbound lanes of the Hutchinson River Parkway, where he was struck by multiple cars and killed.

Following an investigation, Henrys was arrested on June 16, 2021 by the Westchester County Department of Public Safety. He was indicted in June 2021 by a Westchester County Grand Jury for Manslaughter in the Second Degree, a felony, and pled guilty on April 12, 2022, to that charge. Henrys resigned from the Mount Vernon Police Department in April 2022.

The case was before Judge Robert Neary in Westchester County Court, and was prosecuted by the Vehicular Crimes Bureau of the Trials and Investigations Division.
