An apparent fight between two youths in front of a food store in Northwest Washington ended Friday night with a 13-year-old being shot to death, police said. He was one of five people, including two other teenagers, killed in District violence since Friday.

The 13-year-old, Charles E. West, of the 300 block of 54th Street NE, was shot in the face about 10 p.m. in front of Medley's Grocery in the 1400 block of North Capitol Street NW, police said. He was taken to Children's Hospital, where he was pronounced dead at 10:43 p.m.

A short time later, investigators arrested a 17-year-old and charged him with second-degree murder. Sgt. Joe Gentile, a police spokesman, said the shooting appeared to have resulted from "an altercation."

By yesterday afternoon, news of Charles's death had spread at the Richardson Dwellings in Northeast Washington. The third-floor apartment where he lived with his mother and older brother was empty, and neighbors said the family hadn't been there all day.

"He always helped my mother bring the bags upstairs," said Edward Traynham, 22, who lives across the hall. "If you asked him for something, he always gave."

In the most recent of the killings, a man identified as Emmett Pugh, 52, of the unit block of T Street NW, was shot to death about 7 p.m. yesterday in a house in the 100 block of Rhode Island Avenue NW. Police provided few details of the incident.

The other three killings occurred in the first 90 minutes of yesterday morning. Details were sketchy, and none of the victims' names was released.

In the first incident, a 17-year-old was shot three times in the chest and once in the thigh about midnight, apparently during an argument with a man in the 4100 block of Georgia Avenue NW. He was taken to Howard University Hospital, where he was pronounced dead.

Ten minutes later, in the 1100 block of Lamont Street NW, two people were shot, one of them fatally.

Police said the dead man was in his late teens; the other, whose age was not available, was listed in critical condition at Washington Hospital Center.

At 1:30 a.m., police responding to a report of a shooting in the 2600 block of Bladensburg Road NE found two men who had been shot. One, a 21-year-old, was taken in a private car to Prince George's Hospital Center, where he was pronounced dead. The second, a 45-year-old man, was shot in the thigh and reported in stable condition at D.C. General Hospital.
