Mark Anthony Waller was 47 when he was last seen the evening of May 7, 2015, after attending a party on Live Oak Loop in Ellabell, Georgia. He left the gathering and never returned home. That night he wore black Southpole jeans, a dark blue and white striped polo-style shirt and black and yellow Nike shoes.

Waller is described as a white male, 5 feet 9 inches and about 135 pounds, very low-cut brown and gray hair, blue eyes, clean-shaven, with multiple tattoos including a bulldog on his right shoulder, letters on his knuckles, a clown on his right leg and tattoos on both forearms, plus scars on both ankles near the Achilles tendon. His mother says he had cerebral palsy, seizures and bipolar disorder and would not have walked away without contacting her.

The Bulloch County Sheriff’s Office treats the case as a cold, open investigation and has said criminal activity is likely, though foul play remains unconfirmed. The family has heard unverified rumors about violent treatment but no evidence has been produced; one person the family believed might have had key information has since died. Anyone with information, however small, is asked to come forward.
