Michigan police say a deranged lunatic strangled a pregnant teenager and decapitated her boyfriend earlier this week before fatally shooting himself in an attempt to avoid prosecution.

According to reports, 18-year-old Brooke Slocum and her boyfriend 25-year-old Charles Oppenneer made contact with a stranger on Craigslist in hopes of getting involved with a three-way sexual encounter. However, when the swingers arrived at 31-year-old Brady Oestrike’s home, the situation turned into a scene from American Psycho.

Police Chief James Carmody says Oestrike held Slocum slave before she was murdered and stuffed in the trunk of his car. Oppenneer, the boyfriend, well, he didn’t get off that easy: his decapitated body was found in a Grand Rapids park.

Police say after they attempted to search Oestrike’s home, he jumped in his car and led them on a high-speed pursuit, before crashing moments later and ending it all with a bullet to the head.

Police found Slocum’s body in the trunk… the still have not recovered Oppenneer's head.
