This series follows the exploits of real-life bounty hunter "Dog" Chapman and his family chasing down actual fugitives in the Hawaiian Island.

DUANE Chapman, better known as reality TV star Dog the Bounty Hunter, has pledged to track down the fugitive mixed martial arts fighter who allegedly assaulted porn star Christy Mack on August 8.

The brutal attack left Mack with broken bones, missing teeth and a severely ruptured liver, among other injuries. Since it happened, Las Vegas police have been searching for her former boyfriend, Jon Koppenhaver, who legally changed his name to War Machine.

“I believed I was going to die,” Mack said in her harrowing account of the assault, posted online yesterday. “He has beaten me many times before, but never this badly.”

According to Mack, War Machine entered her house at 2am on Friday morning and beat up a man who was with her. Then he sent the man away, forced Mack to shower in front of him, bashed her face, pushed a knife against her skin and said he was going to rape her.

She eventually managed to escape through her home’s back door while he rummaged around in another room.

War Machine has not surfaced since the attack, and there is a $10,000 reward for his capture. Apparently, that has attracted the interest of Chapman (aka Dog the Bounty Hunter), who is threatening to come after the former UFC and Bellator fighter. Chapman gave War Machine 24 hours to hand himself in ... more than 24 hours ago.

War Machine has not responded to the bounty hunter, though he did break his silence on Twitter yesterday to protest his innocence. The fugitive claims he went to Mack’s house in the early hours of Friday morning to propose.

Mack’s account of the incident is completely different, and absolutely horrifying.

“He made me undress and shower in front of him, then dragged me out and beat my face,” she said.

“He pushed the knife into me in some areas such as my hand, ear and head.

“He told me he was going to rape me, but was disappointed in himself when he could not get hard.

“After another hit or two, he left me on the floor bleeding and shaking, holding my side from the pain of my rib.”

War Machine has been imprisoned twice before for committing assault. This time, police have issued seven separate warrants for his arrest, on counts including battery with substantial bodily harm, battery by strangulation, open and gross lewdness, assault with a deadly weapon and coercion.

Meanwhile, one of Mack’s colleagues in the adult film industry, Kendall Karson, has started a fundraising page in an effort to help her friend recover.
