In July 2012, ex-Marine and police officer Robert McClain was sentenced to 20 years and four consecutive life terms for brutalizing his wife and her lover in an hours long attack on September 28, 2008 in Irvine, California. Once McClain learned of his wife’s affair, he asked her to introduce him to her new boyfriend because he wanted to meet the man who would be around his children. Unbeknownst to her, McClain brought knives and guns to the meeting so he could punish both victims because of their affair. According to his wife Summer Lang, McClain was extremely jealous, controlling and violent during the marriage. When he learned his wife wanted to divorce him after 12 years of marriage, he planned the attack on her and her lover, Michael Heflin. McClain was convicted of several felonies including rape, torture, and kidnapping. Although Michael Heflin survived the attacks, he was beaten and stabbed multiple times, resulting in permanent brain damage and other life long injuries. Summer was tortured, kidnapped, and raped but managed to escape after Robert McClain fell asleep.

“What’s scary about this case is if he can do that to his wife he can do that to anybody.” -The Orange County Register

Army veteran Peter Theriault went missing on December 2, 1998 from Irvine, California. Live-in girlfriend Judy Valot, 54, was charged and convicted of second degree murder in January 2000 despite a body, weapon, or any physical evidence. She was found guilty of murdering Peter Theriault and disposing of his body in a California desert because she was convinced he was cheating on her. There was no evidence that Peter was in fact cheating on her. Valot appealed her conviction and was granted a new trial. And again in 2005, Judy Valot was found guilty of second degree murder. She was sentenced to fifteen years to life in prison. Judy Valot was denied parole in February 2013 as she maintains her innocence and refuses to reveal the location of Peter’s body who is still missing to this day.
