Byron Augustus Freeman, 70, went missing from Palestine, Texas, on June 24, 2006, after traveling from Los Angeles to attend a class reunion. He was last seen on U.S. Highway 79 in Franklin, Texas, walking away from his rental car, a gray Lincoln Town Car, which was later found abandoned after running out of gas.

Freeman was believed to be in the early stages of Alzheimer’s disease at the time, a detail investigators consider critical because he may have been disoriented and unsure of his location, possibly thinking he was still in Los Angeles. Despite extensive searches, there have been no significant leads and his case remains unsolved. Authorities have classified him as endangered.

Anyone who saw Freeman, the gray Lincoln Town Car, or who has information about his movements in Franklin or along U.S. Highway 79 on June 24, 2006, is asked to come forward.
