Bobbie Jean Roam Robertson was 38 when she was shot and killed during a robbery at a Fort Smith, Arkansas convenience store on October 12, 1981. She worked as a clerk; the killing was part of a multi-state crime spree that terrorized communities across several states.

Investigators linked Robertson’s murder to Marion Albert Pruett. Authorities say her death was one of five slayings committed by Pruett, who had already killed his wife in New Mexico and a bank loan officer in Mississippi before the Arkansas attack, and who went on to kill two more convenience store workers in Colorado four days after Robertson’s death. Pruett was tried and convicted for Robertson’s murder and received the death sentence.

What information about Robertson’s life or the Fort Smith case might help fill gaps in the timeline or explain how she became a target?
