Prosecutors tried to draw similarities between the two cases to back up a theory that when Harmon felt threatened or abandoned, she killed. Cates called that a stretch.
Prosecutors knew Harmon was furious with Pitts over money, for wanting to move out and for sharing news of Harmon's pregnancy, according to court documents obtained by The Associated Press.
Pitts went missing on Sept. 16, 1988, the day that Harmon drove around Prescott looking for her and saying she'd kill her if she found her, the documents say. Harmon also said she knew how to conceal a killing: by burning a body or dumping it down a mineshaft — a statement a judge said could be included at a trial that was supposed to start last week.
