WAYZATA — Authorities said a Wayzata police officer was struck and killed while trying to remove debris from a highway.

The Hennepin County Sheriff’s Office said Officer William Mathews had pulled over to the side of eastbound Highway 12 about 12:30 p.m. Friday when he was struck by a car. The 47-year-old Mathews was pronounced dead at a hospital.

Authorities said the driver of the car, a 54-year-old Mound woman, stopped immediately and was cooperative. Records obtained show that she had a revoked license and a history of traffic violations.

Investigators said it could take weeks to finish the investigation.

Mathews had been with the department for nine years. He was married and the father of a 7-year-old boy.

Wayzata Police Chief Mike Risvold called it “an enormously sad day.”
