Keith Morrison sits down with Dennis Murphy and Dateline producer Michelle Madigan to discuss their episode, “Simply Diabolical.” In May 2016, 29-year-old Michelle Hadley allegedly sent several threatening emails to her ex-boyfriend, Ian Diaz, and his new wife, Angela. But it wasn’t until Angela called 911 to report that she had been sexually assaulted and that Michelle was responsible for setting it up, that Michelle Hadley was arrested and sent to jail. The only problem was Michelle wasn’t behind the emails, or the alleged plot to have Angela sexually assaulted. She’d been set up by Ian and Angela. Dennis and producer Michelle Madigan tell Keith about the investigative work done by Hadley’s father to try to clear his daughter's name. Dennis shares an extra clip from an interview with one of Angela’s friends, as well as a clip from his interview with Michelle Hadley herself. Plus, our team answers your questions from social media.
