Mitchell Buchanan Jr., 70, disappeared from his Dallas home on October 25, 2006. He was last seen at about 8:00 p.m. on Autumn Woods Trail and had Alzheimer’s disease and other medical conditions. Family and records note he had recently started a medication that caused hallucinations and confusion.

Buchanan left in a gray 1996 Dodge C15 truck despite not having driven for months. The vehicle was found abandoned on October 29, 2006, on the shoulder of Highway 20 near Tyler, Texas; his wallet and identification were not with him. Searches of nearby woods and checks of hospitals and shelters produced no sign of him. He was known to visit casinos in the Shreveport, Louisiana area with family, and investigators considered the possibility he tried to travel there or seek help en route.

Anyone who saw Buchanan, the gray 1996 Dodge C15, or has information about his movements after October 25, 2006, is asked to come forward.
