Knutson and Bedwell were headed to their son’s La Quinta home for a get-together, but they never arrived, according to the San Diego County Sheriff’s Department.

Deputies explained the couple also never returned to their mobile home in Fullerton. Police monitored the area in case the couple returns home.

Knutson and Bedwell last contacted their children around 10:30 a.m., and explained they were going to play the nickel slots at the casino before leaving.

The couple’s children said the only thing that could have kept their parents away from visiting was a traffic accident or foul play.

According to deputies, Knutson and Bedwell’s cell phones last pinged a few miles north of the casino, and then they were shut off.

The couple was last seen traveling in a white 2014 Hyundai Sonata, California license plate 7EHE981, which is outfitted with a tracking device that is similar to OnStar.
