Athell Johnson was 24 and used a wheelchair when he was killed in Columbia, South Carolina, on June 28–29, 2012. He and 23-year-old Jamall Pratt were in an apartment on Garner’s Ferry Road when two men entered, tortured both victims and shot them in the head. Both men died at Palmetto Richland Memorial Hospital on June 29, 2012. A 24-year-old woman who had been injured escaped, flagged down a motorist and led deputies to the apartment; she identified the assailants to investigators.

Authorities charged William Anthony Wallace, 27, and DeAndre Leroy Diggs, 36, with two counts of murder, one count of attempted murder, three counts of kidnapping and two counts of armed robbery, describing the incident as a drug deal gone bad. Wallace was described by the Richland County Sheriff as a career criminal and faced trial for the execution-style slayings. The surviving woman’s testimony was central to the case.
