On August 7, 1989, Debbie Dietz, 29, and her father, Eugene Dietz, were shot and killed at their family-owned automotive paint and body shop in Tucson, Arizona. Debbie’s relationship with her estranged boyfriend, Joseph Rudolph Wood III, had been described as tumultuous and marked by abusive and violent behavior; she had been trying to end the relationship. That morning Wood called the shop to confirm both were present, then arrived and shot Eugene. When an employee announced Eugene had been shot, Debbie tried to call for help. An employee said Wood grabbed her from behind, held a revolver to her chest, and after she pleaded for her life shot her twice; the employee reported hearing Wood say he had told her he was going to do it and that he had to kill her.

Officers were on scene when Wood left the shop; he initially complied with commands to drop his weapon but then picked it up and raised it toward officers, who then shot him several times and took him into custody. Wood was convicted on two counts of first-degree murder and two counts of aggravated assault and was sentenced to death. Anyone who knew Debbie or her family, or who has information about that day, is asked to come forward.
