Manhunt Underway for Shooter of Wash. Trooper

All available officers searched early Thursday for the person who shot and killed a Washington State Patrol trooper during a traffic stop about 20 miles west of Seattle across Puget Sound.

The trooper had stopped a pickup around 1 a.m. Thursday on Highway 16 near Gorst and radioed the location and license plate number, reports the Seattle Times .

When the trooper didn't respond to status checks, a Kitsap County sheriff's deputy went to the scene and found the wounded trooper. He was taken St. Joseph Medical Center in Tacoma where he was declared dead.
