Shooting in US state park

A shooting in a US state park just east of Seattle has left two men dead and four others wounded.

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.
