Suspect in sniper- style shooting in Washington, D.C., kills self.

A suspect who police said had set up a tripod in an apartment along one of Washington’s busiest corridors and randomly fired more than 20 rounds, wounding four people, apparently killed himself Friday night as police prepared to enter the apartment, authorities said.

News of the suspect’s death came about six hours after the 3:20 p.m. shooting, which sent people scurrying for safety and prompted police to tell residents and students in the Cleveland Park and Van Ness areas to shelter in place as they searched for an assailant.

The terror and confusion ended late Friday when the city’s police chief, Robert Contee III, announced that the suspect in the case had been found dead in a fifth-floor apartment, where there was a tripod that police described as a “snipertype setup,” at least six guns and many rounds of ammunition.

Three adults and a 12year-old girl were wounded. Two adults were in stable condition Friday at a hospital; the girl was in stable condition with minor wounds; and a woman who was grazed by a bullet was treated at the scene.
