Seattle police officers responded to a shooting in the Hillman City neighborhood late Monday night that left a 58-year-old man wounded.

Police said 911 calls were received around 11 p.m. after witnesses heard a loud bang in the 4600 block of South Graham Street, followed by a man yelling that he had been shot.

The victim was gone when police arrived a short time later. Officers made contact with him when he arrived at a nearby fire station with a gunshot wound to his leg, police said. He was taken to Harborview Medical Center.

Police said on the department’s blotter that evidence and information from witnesses indicate that the victim may have been “targeted by a known suspect following an ongoing dispute.”

The shooting follows a two-day period during which four people were killed in separate shootings across the city. Mayor Jenny Durkan said Monday both police and community-led efforts are needed to address the recent wave of gun violence.
