Among the dead were the deputy and another person killed at the same location; two construction workers who were found shot nearby; a person killed at another location; and a motorist fatally shot on Interstate 5.
A motorcyclist was shot and wounded at a gas station in the town of Alger, and the trooper was wounded in the arm as the suspect raced along Interstate 5, authorities said.
That suspect, reportedly a man known to Skagit County authorities, eventually turned himself in at a Skagit County sheriff's office in Mount Vernon.
