What would push someone to want to kill a loved one, and what could go wrong along the way? 48 HOURS investigates two cases of love gone badly in a Saturday night double feature to be broadcast August 13, 2016 (9:00 PM ET/PT and 10:00 PM ET/PT) on the CBS Television Network.

At 9:00 PM, Troy Roberts and 48 HOURS investigate the twisted relationship between millionaire health supplement distributor and wannabe rock 'n' roller Dino Guglielmelli; his model wife, Monica Olsen; and the presumed hit man who came into the picture, Richard Fuhrmann, in an encore edition of "The Millionaire, The Model & The Hit Man." Guglielmelli and Olsen were married for seven years. He was a dashing executive who fronted a rock band. She was a model and the mother of two children. But authorities say he was cheating on Olsen all along, and a friend told 48 HOURS he was upset Olsen had returned to modeling. Their relationship fell apart. When he couldn't get his way in the divorce, prosecutors maintain, Guglielmelli asked Fuhrmann to kill Olsen. Fuhrmann went to authorities and agreed to wear a wire. Over lunch, Fuhrmann got Guglielmelli to repeat that he would pay $80,000 to have Olsen killed. What could possibly go wrong?

At 10:00 PM, Troy Roberts and 48 HOURS go inside the investigation of the death of Weight Watchers executive Danielle Thomas, and the murder case against Jason Bohn, a Wall Street attorney, who claimed being neglected by his mother as a child should keep him from spending his life in jail, in an encore of "A Raging Son." Thomas was found dead in June 2012 in the bathtub of an apartment she shared with Bohn. While there was talk of marriage, the relationship had become physically and emotionally abusive. Police found her body surrounded by bags of ice and a fan placed facing the window to remove any scent. Police also found two notes left behind by Bohn, one saying Thomas' death was an accident after a night of drinking. Three days later, Bohn was arrested and charged with murder.

Bohn's attorney asserted he was abandoned by his mother three decades earlier, and he experienced profound neglect and abuse that caused a mental illness called Intermittent Explosive Disorder. His mother, Maureen O'Connell, is now a wealthy publishing executive. But when Bohn was nine years old, O'Connell left him to live with abusive family members, his defense says. His attorney maintains that because of his childhood trauma he shouldn't spend the rest of his life behind bars for killing Thomas. Despite knowing what the defense strategy would be, Bohn's mother paid for his legal bills.

48 HOURS: "A Raging Son" tells of a murder so brutal it made a hardened New York City detective not want to be a cop anymore. It's a case that explores the family ties that led Bohn to that fateful night, hidden stories of domestic abuse, a 9-1-1 call police never responded to, and a horrific accidental call that includes what's believed to be Thomas' last moments alive. "I can't breathe. Help me, Jason," Thomas says. "Help me... Jason, I love you."
