Alfred Guy Cardell Jr. was 25 when he disappeared on August 25, 1985, while diving off Point Lobos State Park in Monterey County, California. He was last seen at Blue Fish Cove after beginning an ascent from a dive but never reaching the surface. His case is classified as a missing person due to a catastrophe with the presumption he drowned, though his remains have never been recovered.

Cardell was a white male, 5 feet 8 inches tall, about 155 pounds, with brown hair and brown eyes. He had a degree in biochemistry from the University of California at Davis, worked as a genetic research assistant, and hoped to attend veterinary school. The Monterey County Sheriff’s Department is handling the investigation.

Did anyone who dived at Point Lobos around August 25, 1985, or who knew Cardell, see anything that could shed light on his disappearance?
