A 16-year-old Renton boy was wounded in the shooting at Lake Sammamish State Park Saturday night that left two men dead, according to the King County Sheriff’s Office.

The teen’s injuries were not life-threatening, said Sgt. John Urquhart, a sheriff’s spokesman.

The teen and two others wounded in the shooting were treated at Harborview Medical Center. The other two wounded were a 20-year-old North Bend man and a 22-year-old Seattle man. The names of the three weren’t released.

A fourth victim was treated at Overlake Hospital in Bellevue. He was beaten after the shooting, and his injuries are not serious, according to Urquhart.

The shooting occurred after a verbal disagreement between two groups escalated into a fist fight and then gunfire at the park.

“Everyone who was shot was part of these one or two groups,” said Urquhart.

In Washington state parks such as Lake Sammamish it is legal to consume alcohol and carry a handgun. Authorities have said alcohol may have played a role in the shootings.

The dead men have been identified as Justin Cunningham, 30, of south Seattle, and Yang Keovongphet, 33, of Kent.

So far, sheriff’s investigators have recovered four handguns and 25 spent cartridges, Urquhart said Tuesday. Two of the guns were in a car stopped leaving the scene. One gun was found in a marsh area near picnic tables, and the fourth was found near Cunningham’s body.

Detectives do not know who shot Cunningham or Keovongphet, Urquhart said. There are several possibilities, but until ballistic evidence is analyzed by the State Patrol Crime Lab, no definitive conclusions should be drawn, he said.

A fourth victim was treated at Overlake Hospital. He was beaten after the shooting, and his injuries are not serious.

Detectives are interviewing witnesses and preparing evidence for the Crime Lab. Anyone with additional information is asked to call the Sheriff’s Office at 206-296-3311.
