Charles Lorraine Hollingsworth, a 38-year-old physician, vanished from South Lake Tahoe, California, on October 26, 1970. He was last seen leaving his office after an argument with a family member and never reappeared. At the time he had recently divorced six months earlier and was described as having ongoing family difficulties that left him despondent.

Born with the surname Rosencrance, he had legally changed his name to Hollingsworth, his mother’s maiden name. Extensive searches of the area turned up no trace, and investigators have considered both foul play and voluntary disappearance without reaching a conclusion. The case remained open and he was later declared legally dead.

Anyone with memories of South Lake Tahoe in 1970 or information about Charles Hollingsworth’s last known movements is asked to come forward.
