Investigation into Line-of-Duty Death of Corporal Grade One Matthew T. “Ty” Snook 1681:

The Delaware State Police is investigating a line-of-duty death after a trooper was killed Tuesday afternoon at the Karen L. Johnson Division of Motor Vehicles (DMV).

On December 23, 2025, at approximately 2:00 p.m., troopers and local law enforcement responded to the DMV, located at 2230 Hessler Boulevard, in New Castle, for reports of an active shooter. The initial investigation revealed Rahman Rose, a 44-year-old man with a last known address in Wilmington, entered the DMV as a customer. Corporal Grade One Matthew Snook was stationed at the reception desk working an overtime assignment. The early investigation indicates Rose approached Cpl/1 Snook from behind and shot him with a handgun. After being shot, Cpl/1 Snook pushed a DMV employee out of the way and told them to run as Rose continued firing multiple rounds at Cpl/1 Snook.

Rose allowed customers to leave the building and remained inside waiting for responding law enforcement. As officers arrived, Rose fired multiple rounds at law enforcement as they approached the building. A New Castle County police officer saw Rose and shot him through a window from outside the DMV.

Cpl/1 Snook was taken to a local hospital, where he later died.

A second trooper, who responded to the scene, sustained non-life-threatening injuries and was not taken to the hospital. A 40-year-old woman was taken to a local hospital for minor, non-gunshot-related injuries. A 35-year-old woman was evaluated for shortness of breath and declined transport to the hospital.

Rose was taken to an area hospital, where he died.
