Detectives with the King County Sheriff's office are still gathering details about a Saturday night shootout in Lake Sammamish State Park. which left two men dead.

Seattle Times:

A fistfight erupted around 9 p.m., and someone from one group apparently fired a gun into the air as a warning. After that, "it sounds to me like everybody pulled out guns," [King County Sheriff's office spokesman John] Urquhart said.

Gunfire between the two groups sent their members and other park visitors scrambling for cover, some ducking into restrooms as up to 20 shots filled the air. When the gunfire stopped, two men had fatal wounds and four more were injured.

"There were lots of guns and lots of gunfire," Urquhart said Sunday. "It boggles the mind how dangerous this was."

Urquhart said it's unclear whether the motive for the shootings stemmed from a gang rivalry, though investigators are looking into that. He said the groups were made up of people of mainly Asian descent.
