It started as a hookup on a dating app, but turned into a twisted tale of kidnapping, rape, murder and 'suicide by cop.' Heidi Carter invites a woman and her boyfriend to a home she was sharing for an afternoon of sex and drug. When Carter's boyfriend, Carey Hammond shows up unannounced, he's angry. Hammond holds the couple at gunpoint, then beats the pair with a baseball and rapes the woman repeatedly. The beaten man is ultimately strangled. The bloody scene is uncovered when Carter calls a friend to help her clean and she finds the dead body.
