WHITESBORO - New York State Police have released new details on the April 11th crash that killed Whitesboro Police Officer Kevin Crossley.

Troopers say a witness, along with video evidence from a nearby business, showed that Officer Crossley was westbound on Oriskany Boulevard when he made a U-turn and began to travel eastbound on the boulevard. His patrol vehicle then collided with a Chevy Avalanche pickup truck near the intersection with Westmoreland Street. Crash data retrieval from Officer Crossley's vehicle shows his speed at the time of the crash was approximately 74 miles per hour, and his actions were consistent with pursuing a violator who was eastbound on Oriskany Boulevard. Officials had previously stated that Crossley had not activated his vehicle's emergency lights or sirens at the time of the crash.

The Onondaga County Medical Examiner's Office determined Officer Crossley's cause of death was multiple traumatic injuries.

Police say Crossley was not wearing a seatbelt at the time of the crash. Law enforcement in New York State are exempt from the seatbelt law. However, the Whitesoboro Police Department policy and procedure manual states that under no circumstances is anyone to drive or operate any village vehicle without a seatbelt.

The driver of the truck involved in the crash, Nicole Moshier-Harris, was issued a traffic ticket for failing to yield the right of way - a violation. Troopers say they do not expect any additional charges.

The 34-year-old Crossley was a native of Whitesboro and a seven-year veteran of the Whitesboro Police Department. He also worked part-time for the Whitestown Police Department and was a Whitesboro volunteer firefighter.
