Grayson Lyons was 45 when he was last seen in Santa Monica, California on November 29, 1994. A British citizen, he lived with friends in Santa Monica and worked as a plumbing, heating and air conditioner engineer. He is described as a Caucasian male, brown hair, blue eyes, 5 feet 8 inches tall and about 165 pounds, and speaks with a British accent.

In the months before he vanished Lyons was reported to be under financial strain, with debt and what was described as a possible nervous breakdown; the State of California, Department of Justice notes he suffered from a behavior disorder. He remained in close contact with family in the United Kingdom before contact stopped. Authorities list him as an endangered missing person and have suggested he might be homeless or using an alias. The Santa Monica Police Department is the investigating agency.

Did anyone in Santa Monica or the UK who knew Grayson notice contacts, sightings, or possible aliases after November 29, 1994?
