San Diego County sheriff's Lt. Kenneth Nelson said Monday that an autopsy will be conducted on 79-year-old Cecil Knutson that could determine when he died.
His wife, 68-year-old Dianna Bedwell, was found Sunday severely dehydrated in their car about 65 miles northeast of San Diego. Trees obscured the car in an off-road area near a Boy Scout camp.
The couple were last seen leaving the Valley View Casino about 25 miles to the west on May 10.
They were going to their son's home outside Palm Springs for a Mother's Day dinner but didn't show up.
Bedwell told authorities they got lost seeking a shortcut.Copyright 2015 FOX 11 Los Angeles | Download our mobile app for breaking news alerts or to watch FOX 11 News | Follow us on Facebook , Twitter and YouTube.
