Daniel Fogg was 24 when he went missing from Marbridge Ranch, a residential facility for mentally disabled men near Austin, Texas. He disappeared on July 17, 1980 after being seen near an administration building; he told others he was going to get a pizza and water but never returned. He had the mental capacity of a 7- to 8-year-old child and was known to be friendly and to talk with strangers.

Investigators later found that Fogg had packed some clothing before leaving, suggesting he may have planned to go somewhere. Extensive searches of the 400-acre facility and surrounding areas turned up no sign of him. There were reported sightings in the Austin area the next day, but no solid leads followed. His father had him legally declared dead in 1987, though no body has ever been recovered and the disappearance remains unsolved.

If anyone knew Daniel, saw him around July 17, 1980, or has information about his movements that day, please contact local authorities.
