Jeffrey Griffin Boyce, 30, of North Bend, Ore. is the primary suspect in the murder of a woman at the Winchester Wayfinding Point along U.S. Highway 101 three miles south of Reedsport, Ore., Oregon State Police Lt. Steve Mitchell said in a news release.
Investigators have identified the woman and are waiting for confirmation from the Oregon State Medical Examiner's Office, Mitchell said.
A couple found the woman's body around 8:20 a.m. Sunday, and the initial investigation indicates the homicide occurred that morning, Oregon State Police said.
On Monday, Boyce was arrested in the Bay Area. Rohnert Park police said Boyce kidnapped a man and forced him to drive in the victim's BMW to a church then back to the shopping center around 4:30 p.m.
Boyce then allegedly carjacked the BMW and drove to Marin County.
San Francisco police informed Bay Area law enforcement agencies Boyce was reportedly mentally ill and was in possession of firearms.
