Sean Dubs was 1 year old when he vanished with his parents, Harvey and Deborah Dubs, from their San Francisco apartment on July 25, 1984. Harvey had placed an ad to sell video equipment; Deborah was on the phone with a friend when two men arrived in response to the ad and the family was never heard from again.

A neighbor reported seeing an unidentified man leave the Dubs residence carrying a box that day, and another neighbor later saw a vehicle leave their apartment. Investigators found a receipt bearing Harvey’s name at Leonard Lake’s remote property, and authorities suspect Sean and his parents were taken to that ranch and killed. The family’s remains were never recovered. Charles Ng was later convicted of multiple murders and Leonard Lake died by suicide in custody, but the Dubs family’s exact fate remains unresolved and the case is classified as a non-family abduction.

Anyone with information about the Dubs family or their movements on July 25, 1984, is asked to contact the San Francisco Police Department.
