"Dog the Bounty Hunter" tweeted on Monday that he plans to track down MMA fighter "War Machine" and bring him to justice for allegedly beating his porn star ex-girlfriend, according to Fox News on Wednesday. Professional mixed martial arts fighter Jon Koppenhaver, better known as "War Machine," has not surfaced since the brutal attack on Christy Mack last week. Duane "Dog" Chapman vowed on his Twitter account to hunt down "War Machine" if he doesn't turn himself in to police.

Koppenhaver reportedly entered Mack's Las Vegas home early Friday morning and severely beat a man that was with her, before sending him away. He then forced Mack to shower in front of him, beat her and threatened to rape her while holding a knife against her skin. Mack apparently was able to escape through a back door while Koppenhaver was distracted in another room. "War Machine" has since been on the run.

Mack was left with 18 broken bones, several missing teeth, a ruptured liver and a fractured rib as a result of the attack. Said 23-year-old Mack, "He has beaten me many times before, but never this badly." She went on to say that she believed she was going to die. Las Vegas police have unsuccessfully been searching for "War Machine," and there is a $10,000 reward for his capture.

American bounty hunter and reality TV star Duane "Dog" Chapman is reportedly outraged over Mack's vicious beating. On Monday, 61-year-old Chapman tweeted that "War Machine" had 24 hours to turn himself in before him and the rest of his bounty hunting crew track him down. Chapman publicly warned 32-year-old Koppenhaver that "You got 24 hrs to turn yourself in or I am Coming After YOU!"

A follow-up tweet on Wednesday from Chapman to "War Machine" said that time is up and beware of the dog, along with a hashtag to promote his new CMT reality television series "Dog and Beth: On the Hunt." Chapman told mmamania.com that he is serious about bringing the elusive "War Machine" to justice. According to the website, Dog has been on the case for several days, way before warrants were issued.

Seven arrest warrants have been issued for "War Machine." Mack says she broke up with Koppenhaver in May, and she gave an account of the attack on her Twitter account, along with photos of her injuries. Reportedly, one of Mack's family members reached out to "Dog" to help law enforcement locate Koppenhaver. Said "Dog," who has friends in the MMA, "We heard about it right away. And there was a couple of people who requested that we get involved so, that's what I do for a living." Chapman claims he's close to an arrest and confident that he will be the one to bring "War Machine" to justice.
