John Dewar has been missing since Tuesday at noon. His wife Marion says he left to go run errands, but didn't take his cell phone, or his blood pressure medicine. She says the 73 year old suffers from memory loss, and may have become confused and disoriented. Longtime family friend Phil Coppock has been posting flyers of Dewar at his favorite hang-outs, hoping someone will say they've spotted him. He says he won't stop looking for him until Dewar is found. He says, "If you think about yourself, in that condition, you'd want your friends to do everything they possibly could. This is what friendship is about, and I can't imagine not doing this until we find him." Dewar took his white 1992 Chevy conversion cab with license plate #6PAP632, framed with the word "Coronado." If you have any information, call Chico Police at (530) 895-4911.
