Willard Arent Bennett, 73, left Olympia, Washington in November 2013 in his 1994 white Dodge Ram camper van on his usual winter migration toward Arizona. He was last confirmed on November 12, 2013 in East San Diego County, California, when he bought gas. Family members say he was in the early stages of Alzheimer’s disease and dementia and that he had promised to keep weekly phone contact with his daughter, calls that went unanswered after the gas purchase.

Bank records show no transactions after that November purchase, and months later his van was located in San Diego County with no sign of him. The San Diego County Sheriff’s Department is handling the investigation, and the case remains open. Little else is publicly known about his movements after the last sighting.

If anyone saw Willard Bennett, knew his planned route, or has information about the van found in San Diego County, please share what is known with investigators.
