The skull of a man beheaded by a killer who murdered his pregnant girlfriend has been found - five years after the twisted slayings.
Twisted Brady Oestrike enticed Brooke Slocum and her boyfriend Charles Oppenneer into his home after they arranged to meet for sex via the US site Craigslist.
Miss Slocum was eight-months-pregnant when she was strangled to death and her boyfriend was beheaded in Wyoming in 2014.
She was kept hostage for five days and repeatedly assaulted, tortured and forced to smoke marijuana.
But only parts of Mr Oppenneer's remains were ever found, until now.

A skull discovered in Michigan last week is believed to be that of the 25-year-old, Fox News reports.
"It was just a long, unanswered question and more than anything, we're just happy to report to the family this piece of information so that we can have some closure for them," Wyoming Police Capt James Maguffee said.
Horrifying footage - caught on cameras that Oestrike had installed in his home - showed 18-year-old Miss Slocum being tortured before she was strangled to death and dumped in the boot of his car.
Her unborn daughter, Audi Lynn, also died.
Oestrike had multiple whips, swords, bondage tools and weapons in his Wyoming house.
There were also nooses with dolls hanging from them, bloody clothes, lingerie, Tasers, a machete and sex toys.
Police released footage that shows Oestrike preparing his home just before he murdered the pair.
He is seen holding a gun as he paces around a room that has ropes hanging from the ceiling and a dog cage in the corner.
Through multiple interviews, police uncovered disturbing details about Oestrike, including what one person described as a "fetish for guns."
Police found a number of guns all over his house.
Miss Slocum was held for after she was kidnapped on July 12, 2014.
On one of four cameras set up in Oestrike's home it shows Miss Slocum with handcuffs on at 1am the following day.
He had put a chain around her neck that was bolted to a bathroom floor.
She was then attached to a pulley system suspended from the ceiling.
After tracing a number of emails between them and the killer police visited his home in Wyoming , Michigan, armed with a search warrant.
But as officers watched Oestrike’s house he fled leading cops on a chase.
A SWAT team had been called in to assist in the search for Oestrike as they suspected he was armed with 'assault-style' weapons. It only ended when he crashed his car and died.
