Off-roaders found Cecil Knutson and his wife, Dianna Bedwell, 68, Sunday afternoon near a Boy Scouts camp on the Los Coyotes Indian Reservation about 105 kilometres northeast of San Diego, sheriff's Lt Ken Nelson said.
Bedwell wasn't able to tell authorities when her husband had died, but an autopsy to be conducted by Tuesday could help answer that question, he said.
Knutson's body was near the car and Bedwell was inside the vehicle, he said.
"They were really off the beaten path. We were really surprised that the vehicle they were driving, a sedan, was even able to get out there," he said Monday. "It was so rural that it took two weeks for even off-roaders to find them."
"Please continue to keep the family in your prayers," it read.
But Bedwell's son spoke briefly to the Orange County Register. "I'm just so concerned with my mom right now," Robert Acosta told the newspaper. "To be in the middle of nowhere for two weeks is a lot given her age."
Bedwell remained hospitalised and hadn't spoken with authorities beyond an initial 10-minute interview.
The husband and wife, who were diabetic, were last seen on surveillance footage leaving the Valley View Casino in Valley Center, about 40 kilometres west of the wilderness camp, on May 10.
Knutson and Bedwell were both retired school bus drivers and were married for more than 25 years, the Register reported.
