Jon Koppenhaver (aka War Machine) is really in trouble now. Dog the Bounty Hunter is offering to help Las Vegas police track down the MMA fighter, who allegedly viciously attacked his ex-girlfriend, porn star Christy Mack, on Aug. 8.

Duane Chapman (aka Dog the Bounty Hunter) took to Twitter on Aug. 12 to warn MMA fighter Jon Koppenhaver that he has “24 hrs to turn” himself in, before Dog comes after him personally. Dog seems livid that Jon has apparently been evading police after he allegedly assaulted ex Christy Mack on Aug. 8, leaving her with 18 broken bones in her face, a fractured rib, and a ruptured liver, among other serious injuries. See all of Dog’s angry tweets after the jump.

Jon is reportedly the Las Vegas Police Department’s “primary suspect” in the shocking assault against Christy and her male friend. Though Jon has defended himself on Twitter, claiming that he’s “not a bad guy,” Dog is clearly not buying it. The bounty hunter and reality TV star took to Twitter to urge Jon to turn himself in — or else.

Christy, 23, had been broken up with Jon, 32, for about three months when he showed up at her home unannounced on Aug. 8 and allegedly assaulted her and a male friend who was there at the time. While Christy’s friend didn’t sustain any serious injuries, she says she suffered 18 broken bones in her face, a fractured rib, and a ruptured liver.

She took to Twitter on Aug. 11 to share an emotional statement, in which she said that she’s “healing fast and well” and that she appreciates “all of the prayers and visits I have received over the past few days.” Christy also revealed shocking and graphic images of her body after the attack (viewer discretion strongly advised).

Police are offering a $5,000 reward for “any information that leads to his apprehension and arrest.”

War Machine also joked about killing Christy during an interview from July 2013.

So what do YOU think of all this, HollywoodLifers? Are you glad that Dog is going after Jon? Let us know.
