Loy Cosby was 87 when he disappeared from Sweetwater, Texas. He was last seen the morning of June 2, 1998, after his wife found the front door of their lakeside cabin open while she slept. Cosby, who had dementia and short-term memory loss, was observed walking along a road near Interstate 20 north of the lake dam and was never heard from again.

Cosby was a former shipyard worker who suffered from gout and walked with a slight limp. He was wearing a light-colored button-down shirt and khaki pants. Investigators and volunteers conducted extensive searches but turned up no clues. Cosby had mentioned traveling to California, so authorities considered the possibility he accepted a ride, but no evidence emerged to support that.

Anyone who knew Loy, saw him in the area that morning, or has information about possible sightings afterward is asked to come forward.
