Three case’s of threesomes gone horribly wrong, ending in a death in each case. Bringing a third person into a relationship can become dangerous territory if all parties aren’t in agreement to the arrangements. These are the stories of Heidi Kathleen Carter of Indiana and a couple she met on a lesbian dating site partaking in a threesome when Heidi’s boyfriend walked in on them and freaked out. A Pastor who pressured his wife to allow a third person join them, and an Australian couple who invited a third male to join them in a sexual act that ended up with the boyfriend in a jealous rage.
