A Dorchester man was ordered held without bail Wednesday at his arraignment on charges fatally stabbed a friend early Tuesday.

Lester James, 24, and Francis Kargbo, 23, had been on James's third-floor porch at 92 Sumner St. for several hours when they got into an argument that turned physical and ended with James plunging a knife into the left side of Kargbo's chest, Assistant District Attorney Gretchen Lundgren said at James's arraignment in Dorchester District Court this morning.

Kargbo ran down the stairs and into the street where he collapsed, Lundgren said, adding that firefighters, who were the first to respond, found James standing over Kargbo as his blood and life drained out of his body. Lundgren said that detectives with a search warrant entered the unit last night and found "a large amount of blood" on the porch, along with a blood trail from the porch down the stairs and to the street.

Lundgren said that James has assault-and-battery convictions dating back to when he was still young enough to be tried in juvenile court. Judge Robert Baylor agreed with her request to hold him without bail, at least until a probably cause hearing on Sept. 22.
