King County Sheriff's deputy John Urquhat says several people are in custody following the violence that erupted last night as a group of people were having "a party" in Lake Sammamish State Park.
The Washington State Patrol tells KOMO-TV that two in custody are believe to have been the attackers.
Urquhat says authorities still don't know what led the shooting. He said the wounded were taken to a Seattle hospital, but he gave no information about their conditions or the names of the dead and injured.
