Chilling CCTV footage has been released showing a man setting up a disturbing torture chamber where he killed a woman who was eight months pregnant.
Police in Wyoming, Michigan, described the Craigslist killing as "one of the most brutal" cases they've ever seen.
Brady Oestrike held Brooke Slocum, 18, captive for five days in a dog kennel before murdering her in July 2014.
He had met up with Slocum and her boyfriend, Charles Oppenneer, 25, after arranging to have sex with her through a Craigslist ad. The couple was selling sex for cash.
But Oestrike had other ideas: He killed Oppenneer by cutting off his head and then took Slocum home to his lair.
Wyoming Police Department released CCTV footage from inside Oestrike's torture cell that show the hours leading up to her murder.
He can be seen prepping a dog kennel and moving weapons around.
Guns, swords and bondage items were among the belongings recovered by police. They also found a child's sippy cup and a baby doll with a noose. Stuffed animals tied together with handcuffs were unearthed as well.
Documents, including a "sex slave contract," were discovered.
Ropes hanging from the ceiling were used to operate Slocum's arms like a puppet.
Wyoming Police Chief James Carmody said,
I think it was pure evil from start to finish. It definitely had a profound effect on all of us. It's very disturbing. There's no way you can say that you get used to that stuff, because you don't. We always try to find a reason for someone acting like this. Sometimes there isn't one.
Oestrike shot and killed himself after a high-speed police chase on July 17, 2014.
Slocum's body was found in the trunk. Her baby, who had already been named Audi, was confirmed dead.
It is believed Oestrike was trying to dispose of the body when he was caught.
