UPDATE: Deadly force justified against suspect in Del. trooper death

(AP) – Delaware's attorney general has released a report confirming that the use of deadly force was justified in the killing of a man who exchanged gunfire with police during a lengthy standoff after fatally shooting a state trooper.

In a report dated Tuesday, authorities said 26-year-old Burgon Sealy Jr. immediately began firing at officers who converged on his family's house in Middletown after he shot and killed Cpl. Stephen Ballard in the parking lot of a convenience store last April.

After a standoff of almost 20 hours, during which additional shots were fired, Sealy emerged from the home holding a handgun. Eleven officers opened fire on Sealy, who fell to the ground and was shot at again as he appeared to be reaching for another gun in his waistband.
