Ep 5. Diana Haun & Michael Dally

In episode 5 of season 6 of Killer Couples, the focus is on Diana Haun and Michael Dally, a couple whose passionate love affair had a dark and deadly side. Diana Haun was a married mother of three who was working as a dental hygienist when she met Michael Dally, a married man who worked as a computer technician. The two began an intense affair that would ultimately lead to murder.

The episode starts with a look at the early days of Diana and Michael's relationship, which began in 1995 when they met at the dental office where Diana worked. Despite the fact that both were married to other people, they quickly became passionate lovers, meeting secretly for rendezvous that often lasted into the early hours of the morning. But their affair was not without complications – Michael's wife, Sherri Dally, suspected that he was cheating on her and hired a private investigator to follow him.

Rather than ending their affair, Diana and Michael took extreme measures to keep it a secret. They even went so far as to plan Sherri's murder, hoping that with Sherri out of the picture, they could be together openly. On May 6, 1996, Michael lured Sherri into the family van under the pretext of taking their son to a baseball game. Instead, he drove her to a remote location where Diana was waiting. Together, they strangled Sherri and left her body in a canyon.

The murder of Sherri Dally shocked the community and left her family devastated. Michael and Diana were quickly identified as the primary suspects, and both were arrested and charged with the murder. While Michael tried to pin the blame solely on Diana, claiming that she had forced him to commit the murder, Diana had a different story. She claimed that Michael had been the mastermind behind the whole plan and that she had only gone along with it because she was in love with him.

The trial that followed was emotional and intense, with both Michael and Diana accusing each other of being the driving force behind Sherri's murder. In the end, the jury found both guilty of first-degree murder, and they were both sentenced to life in prison without the possibility of parole. The episode ends with a look at the aftermath of the trial, including interviews with family members of both Sherri and Diana, who continue to struggle with the aftermath of this heinous crime.

Throughout the episode, viewers get an inside look at the complicated relationship between Michael and Diana, including how their affair began and the various factors that led to their decision to commit murder. The episode is a chilling reminder of the destructive power of passion and the devastating consequences that can result from making choices motivated by love and desire. Overall, Killer Couples season 6 episode 5 provides a gripping, intense, and thought-provoking look at one of America's most notorious cases of spousal murder.
