A 26-year-old man was shot in the back and killed last night in the parking lot of a condominium just off Dupont Circle, police reported.

The shooting occurred about 9:30 p.m. in a parking lot at the rear of the Appolline Apartments, in the 1300 block of New Hampshire Avenue NW.

The victim was taken to George Washington University Hospital, where efforts to save him failed.

He died about an hour later.

The victim's name was withheld pending notification of relatives. Police said he carried a Pennsylvania driver's license that indicated he had lived recently in Pittsburgh.

He also had other identification suggesting that he may have been working in this area.

The killing was the first in months in the area, an affluent section that has been largely immune to the rash of shootings that has plagued many other sections of the city.

Police indicated last night that they knew of no motive in the slaying, and had no suspects.

One resident of the Appolline said he had heard a shot about 9:30 p.m. and looked out into the parking lot to see a man lying there.

Although witnesses told of hearing what sounded like a single loud explosion, police said the victim was shot at least four times and that the bullets were fired from behind him.

The man's wallet was found beneath him, an investigator said. Although that could have indicated a robbery attempt, the investigator said the man may have been carrying the wallet in his hand because the jogging suit he was wearing lacked a pocket.

"There's no sign of robbery or anything," the investigator said. "It's just one of those strange things."
