Wallace was last seen on the corner of May Street and Park Avenue in Worcester, Massachusetts on April 2, 1991. His mother saw him as she drove by and said he appeared to be waiting for someone or something; she thought he was waiting for a bus. Wallace was carrying a tote bag over one of his shoulders at the time of his disappearance, which contained medical supplies, including some Attends diapers. He is not believed to have been carrying any money or identification. He has never been heard from again.

Wallace resided in the 1000 block of Main Street. His mother became concerned when he did not answer her letters and she went to his apartment and discovered that it had been meticulously cleaned. His possessions, including a sculpture he made and a box of Attends diapers, were left behind.

Wallace was employed as a house painter in 1991. He frequently visited churches and libraries and has an interest in religion, particularly Hare Krishna. He has disappeared before, once turning up in Dallas, Texas. His case remains unsolved. He was declared legally dead in 2005. (Information Provided by: The Charley Project)
