An 18-year-old man has been charged in the murder of a popular disc jockey on South Street, while a second suspect remains at-large.

Police arrested Josephe Murray, of Reedland Street near 58th, on Wednesday. Murray and an accomplice fatally shot Tom Watson, 36, during a robbery as Watson entered his apartment on South Street near 3rd above the Haagen Dazs ice-cream store Saturday, police said.

Watson's body was found behind the counter in the ice-cream store by a friend who had dropped him off, friends said. Medics pronounced him dead at the scene at 3:37 a.m.

Watson performed at local clubs as DJ Fenicx and was a cook at Tavern 222 on South Street, according to friends.

A police source said investigators recovered an undisclosed amount of cocaine and marijuana in Watson's apartment. The source said the drugs appeared to be a larger amount than for personal consumption, but said there is no indication Watson was selling the drugs. Police have not said whether the drugs played any role in his murder.

Murray is charged with murder, robbery and related offenses. Police are still searching for a second suspect.
