Police said the man who fired a sawed-off shotgun outside a Northeast supermarket and was fatally shot by a D.C. police officer Tuesday night was Charles M. Gaines, 18, of the 1300 block of Bryant Street NE.
They said a preliminary investigation indicated that Officer Mark Shedrick was justified in his use of deadly force.
Shedrick, a 15-year member of the force, has been placed on administrative duties pending the outcome of the internal investigation, a routine step in such cases, police said.
Police said the incident began about 8:30 p.m. when Gaines entered the Giant Food store in the 900 block of Rhode Island Avenue NE. He passed two police officers and a security guard who were talking near the front of the store and headed for the bakery, police said.
Once in the bakery section, Gaines inappropriately touched a Giant employee and then picked up a loaf of bread and headed for the checkout lanes, police said.
The employee alerted the security guard to Gaines's conduct, police said.
The security guard approached Gaines, who began to yell and walk out of the store.
A manager then alerted the two police officers that the man appeared to have a gun, police said.
The officers and the security guard followed Gaines into the parking lot and ordered him to halt about 225 feet from the store's entrance, police said.
When Gaines turned around, a sawed-off, double-barreled shotgun fell to the ground, police said.
As Gaines bent to pick up the weapon, the officers ordered him to stop, but he grabbed the weapon anyway and fired at least one shot that did not hit anyone, police said.
Shedrick, who had drawn his weapon, then fired at Gaines, hitting him several times, police said. Gaines was pronounced dead at Washington Hospital Center, police said. The other officer and the security guard, whose identities were not released, did not fire, police said. They said they did not know why Gaines had the weapon or refused to stop.
Police said investigators with the department's Force Investigation Team are continuing to interview witnesses and review videotaped footage taken from security cameras at the Giant and neighboring businesses.
