Schackart and Charla Regan had known each other since high school and they continued to be friends at the University of Arizona.

On March 8, 1984, Schackart told Regan he needed a place to stay since his parents had kicked him out of their house. He also told her he needed to talk to her about his wife filing rape charges against him. They went to a Tucson Holiday Inn where Schackart raped Charla at gunpoint, hit her in the face with the gun, strangled her to death and stuffed a large sock into her mouth.

He later reported the killing to the police and claimed he had not intended to kill Charla.
