Crescent City woman was killed and her husband seriously injured Thursday afternoon in a crash near Glenhaven, southeast of Ukiah.

Joyce Rakestraw, 77, died in the single-vehicle wreck, which occurred shortly after 12:37 p.m. on Highway 20 at Mary Street, according to the California Highway Patrol.

Her husband, Raymond Daniel Rakestraw Jr., 80, sustained major injuries, the CHP told the Lake County News.

Raymond Rakestraw was driving a 2005 Buick Park Avenue eastbound on Highway 20 approaching Mary Street, driving 45andndash;50 miles per hour, when the vehicle drifted off the highway's south edge, according to the CHP.

The CHP said the car struck a pier and overturned.

Joyce Rakestraw, riding in the front passenger seat, was pronounced dead at the scene by Northshore Fire Protection District personnel, according to the report.

While the wreck remains under investigation, the CHP believes prescription medication is a factor.
