Two-year-old Thomas Dean Gibson vanished from his Glendale, Oregon, front yard at about 11:30 a.m. on March 18, 1991. He was last seen wearing a purple sweatshirt, grey pants and black-and-white checkered tennis shoes; he had brown hair, brown eyes and a noticeable gap between his front teeth. His father, a Douglas County sheriff’s deputy, said he left Thomas in the yard while he went for a jog and had fired his service gun at a stray cat on the property before leaving.

Initial searches turned up nothing. Investigators later focused on the boy’s father after finding inconsistencies in his statements and his behavior during the search. Years afterward, Thomas’s older sister—then four—told investigators she had seen their father assault Thomas and put him in his patrol car on the day Thomas disappeared. That account prompted an arrest and criminal proceedings against the father.

The boy has never been found and questions remain about whether Thomas was accidentally struck when the father fired at the cat or whether he was intentionally harmed. Does anyone have information about Thomas, the family, or that neighborhood in Glendale in March 1991?
