Courtroom Autopsy

The Love Triangle That Ended in Murder by Hammer


Listen Later

A husband is beaten with a hammer. His wife says an intruder did it. Then the story changes again… and again.

When police arrived at the home of Dale Harrell and Marissa Devault, they found Dale barely alive and Marissa covered in blood. What followed was one of Arizona’s most bizarre murder cases — a trial filled with conflicting stories, allegations of abuse, a suspicious attack on the defendant, a roommate with severe memory problems, and a secret relationship prosecutors claimed revealed the true motive.

In this episode, we break down the murder trial that drew constant comparisons to the Jodi Arias case. From the failed intruder defense to the prosecution’s “love triangle turned insurance scheme” theory, we analyze the evidence, trial strategy, witness credibility, and the legal issues that made this case unforgettable.
