A badly decomposed body found Monday in a wooded area in Prince George's County was identified yesterday as a 17-year-old youth sought in connection with a gang rape and shooting that left one person dead and two wounded earlier this month in Camp Springs, police said.

Police officers, using a dog to chase a murder suspect fleeing from the District, stumbled across the body of Don Joseph Walker about 4 a.m. Monday, said Pfc. Carol Landrum, a police spokeswoman.

Walker's body had decayed beyond recognition, leading investigators to suspect that it had been in the woods for at least two weeks. The youth had been shot, sources said.

Prince George's County police earlier this month issued a first-degree murder warrant for Walker in connection with the Sept. 8 slaying of Sulaiman Yusiff Malik, 18.

Malik, who lived on 57th Place in Southwest Washington, was shot once in the head execution-style by a group of armed men who burst into an apartment he was visiting in the 5400 block of Morris Avenue in Camp Springs.

Two other men were shot in the head and survived; a fourth man, his hands bound, escaped by diving 12 feet out of a second-floor window and racing across a courtyard, police said. Two women in the apartment were raped repeatedly, police said.

Police immediately began looking for Walker, who was the only gunman not masked during the attack and who was recognized by his victims.

Sources said that homicide investigators feared that Walker would be killed before he could be arrested. Police are still searching for the other gunmen.
