Alger: A terrifying shooting spree that stretched from a small northwest Washington town onto the state's busiest highway left six people dead and two more wounded on Tuesday.

The man, who turned himself in, was known to authorities as "someone with a mental illness," Trooper Keith Leary said. State Department of Corrections officials are "99 per cent sure" the man is a 28-year-old with a lengthy criminal record, spokesman Chad Lewis said.

The dead included a Skagit County sheriff's deputy and the wounded included a Washington State Patrol trooper shot while trying to chase the shooter down on Interstate 5, the State Patrol said. A suspect in the shootings has surrendered.

The victims were found at multiple crime scenes.

A motorist was shot and killed on Interstate 5 as the suspect fled south.


After the shootings in the Alger area, the armed man raced south on Interstate 5 at speeds in excess of 90 mph, with troopers, sheriff's deputies and Mount Vernon police in pursuit, Leary said.

The first shootings were reported shortly after 2 p.m. on Tuesday and the suspect was taken into custody by about 4:30 p.m.
