A divorced mother of four, two wealthy doctors and a twisted love triangle that ends in murder ― was the killing of a prominent doctor a random act of violence or the result of a deadly obsession? On a quiet summer morning, Dr. Joseph Sonnier was found brutally murdered in his stately northwest Texas home. Who could have wanted to kill a so-called renaissance man beloved by his small community? Police are stumped until they receive a tip out of the blue, leading them to the man who pulled the trigger. After two trials, will justice be served?

In this program, Richelle Shetina, the woman at the center of the love triangle, speaks out about the murder and her ex-boyfriend Dr. Mike Dixon, who is accused of hiring a hitman. Additionally, the program features an interview with the accused murderer's daughters, who speak about their father and how they feel about what he's done. "20/20" correspondent Ryan Smith's extensive report also includes interviews with Dr. Sonnier's sons, Dr. Dixon's son, investigators, prosecution and defense teams, as well as interrogation tapes and key crime scene photos.
