A man shot and killed a Delaware state trooper outside a convenience store on Wednesday and later barricaded himself inside his house, where he continued to fire shots at officers, police said. The trooper was shot multiple times and died at a hospital, Col. Nathaniel McQueen, the state police superintendent, said at a news conference. "This is a sad day for our state and for the Delaware State Police family," McQueen said. The trooper, was shot around 12:10pm after he approached a vehicle in the parking lot of a convenience store, the AP reports. McQueen said the vehicle had two suspicious people inside. One man got out of the car and shot the trooper several times before running away, McQueen said. The other man was arrested at the scene.
Police tracked the gunman to his home where the suspect, alone in the house, refused to leave and fired several shots at officers surrounding the home, said Master Cpl. Gary Fournier, a state police spokesperson. No other officers were injured. Hostage negotiators were on the scene and established contact with the man in an effort to get him to surrender peacefully, Fournier said. But there was no quick resolution as the standoff stretched into the late afternoon. Police used a robo-calling system to tell residents in the areas to stay inside and lock their doors. The Appoquinimink School District went on lockdown, keeping all students and staff inside school buildings. Police have identified the man, Fournier said, but have yet to release his name.
