Concern grew in the autumn of 2011 when David Christopher Allor, 56, stopped communicating while in Enterprise, Alabama. He was last seen near his mother’s home on Westfield Drive and had brown hair, brown eyes, stood 5 feet 9 inches, and weighed about 150 pounds. David had unspecified health problems and may have needed medical attention when he vanished.

Reports say he might have been trying to get to Detroit, Michigan, where he had lived previously, and that hitchhiking was a possibility. His case is classified as endangered missing. Few details exist about his last movements, and that gap has left his family without answers.

If anyone saw David in or traveling from Southeast Alabama toward Michigan in late 2011, please share what you know with investigators.
