Two gunmen opened fire at a state park in Washington State Saturday night, killing two men and wounding four others.
Troopers were among the first on the scene after a park ranger called 911 to report a shooting around 9 p.m.
The King County Sheriff's Office says it has some suspects in custody, but is still looking for others.
The park has been closed and patrons are being held until they have been questioned by police.
They went on to say that several guns were found in a car and at least one gun was found at the scene.
The victims have not been identified and police are still investigating the scene.
