One of six people shot on a single street in seven days in one Southeast Washington neighborhood died over the weekend, according to police who continue to search for a reason behind an apparent neighborhood feud.

Andrew McPhatter, 28, of Southeast, was wounded about 10:50 a.m. Wednesday in the 3500 block of Wheeler Road, in Congress Heights. He was found shot in the driver’s seat of a Buick GS 350 in the middle of the road. Police said he died Sunday.

The shooting of McPhatter was the latest in a series since Feb. 23 between the 3300 and the 3900 blocks of Wheeler Road. Police have said they believe the violence is part of a neighborhood dispute.

The shootings began Feb. 23 when four people were wounded by gunfire in three incidents over two hours. A woman was shot on Wheeler Road on Feb. 27 and McPhatter was shot Wednesday, drawing the police chief, Peter Newsham, to the scene.

Interviews with residents and police last week indicated some sort of ongoing dispute is at the heart of the violence, though investigators say they have not been able to pin down the nature of the argument. Many residents said they were too afraid to talk and others declined to describe what started the violence.

Police arrested two brothers who live on Wheeler Road and charged them in connection with the first of the three shooting incidents on Wheeler Road. But the arrest affidavit does not describe any possible motive.

Newsham has said that many of the victims are not cooperating with police. At a hearing before a D.C. Council committee on Friday, Newsham said that “grown adults are out there glamorizing carrying a firearm. That needs to stop. There is no glory in carrying a firearm. There is no glory shooting up Wheeler Road at 11 a.m. a couple blocks from a school.”

Efforts to reach McPhatter’s relatives have not been successful; he lives about a six-minute walk from where he was shot. A relative of the brothers charged in the one shooting declined to comment Friday.
