Summary based on the NamUs case record (MP7568) and 5 other sources
Robert Wayne McCullar, a 39-year-old man, went missing from Denton, Texas, on February 20, 1995. McCullar, who had severe mental disabilities and functioned at the level of a five-year-old, was a resident at the Denton State School (now the Denton State Supported Living Center), a facility for mentally disabled adults. He walked away from the school that evening at around 6:00 p.m. and was never seen again. McCullar had several medical conditions, including violent seizures that required daily medication. At the time of his disappearance, he was wearing a white button-down shirt with green stripes, khaki pants, white sneakers, and a tan protective helmet. He also had distinguishing scars on his abdomen and forehead.

McCullar’s disappearance is classified as endangered due to his severe medical needs and mental condition. Despite multiple investigations over the years, no significant leads have emerged, and his whereabouts remain unknown. Local authorities, including the Denton Police Department, continue to seek any information that may help resolve this long-standing case. His family and law enforcement hope that public awareness might lead to new clues or witnesses coming forward.
