A Delaware state trooper shot and killed a 35-year-old Philadelphia man in Claymont early Sunday after the man allegedly dragged the trooper with his car.

The dead man was identified Sunday night as Michael L. McKillop of Rosebury Street in the Whitman section of South Philadelphia.

The trooper, whose name was not released, was responding to a burglary alarm at the Northtowne Plaza Rite Aid shortly after 1:30 a.m. when he saw a car parked in back of the store, according to a news release from the Delaware State Police.

As the trooper got out of his vehicle, he saw a man later identified as McKillop leave the Rite Aid and quickly climb into the parked burgundy 1999 Oldsmobile, which Philadelphia police had reported stolen on Sunday.

He allegedly tried to flee as the trooper stood at the car's open driver's-side door. Police said McKillop put the car in reverse and dragged the trooper before striking the officer's patrol car.

McKillop allegedly tried to drive off again, still dragging the trooper.

The trooper fired, striking McKillop in the upper torso, according to investigators.

The trooper then administered first aid until medics arrived. McKillop was flown to Christiana Hospital, where he died shortly after 4 a.m.

The trooper was treated for lacerations and contusions at Wilmington Hospital and released, police said.

The 16-year state police veteran, assigned to Troop 1 in Claymont, has been placed on administrative leave pending the outcome of an investigation.
