It’s been almost a week since mixed martial arts fighter Jonathan Koppenhaver, known as War Machine, allegedly put ex-girlfriend Christy Mack in the hospital, and the 32-year-old, whose Twitter bio reads “I do Alpha Male s---,” is still nowhere to be found.

Koppenhaver has a history of violent behavior outside of his profession. He has already served two prison sentences prior to his alleged altercation in Las Vegas with Mack, a petite adult film star who is currently suffering from 18 broken bones, missing teeth, a fractured rib and a ruptured liver.

In 2007, Koppenhaver was found guilty of choking a Las Vegas man unconscious during a parking lot scuffle. One year later, he pled guilty to a misdemeanor charge of assault and battery and was fined and sentenced to probation.

Three years later, Koppenhaver was sentenced to one year in jail for a felony assault conviction following fights at two different bars in the San Diego area. During his jail time, he regularly updated a blog laden with expletives and violent declarations.

As I write this, there is one guy in here for slapping his wife, one here for yelling at his wife, and one here for beating some guy's a__ that disrespected his wife. WTF!? If your wife is being a b____ you can't slap her, if your wife is yelling at you, God forbid you yell back, and if some a__hole hurts your wife, you can not protect her! LMFAO! What in the F__K! is REALLY going on!? Next thing you know it will be illegal to f__k your wife! This country forces you to be a b___h!

The pro fighter continued to post on Twitter nearly 24 hours after the latest incident, claiming his innocence.




This resulted in a flurry of angry Twitter users siding with Mack, who released graphic photos of the incident on Monday. The 23-year-old Illinois native said she genuinely believed she was going to die.







Some users sided with Koppenhaver, claiming Mack deserved the beating due to her profession.










Duane Chapman, aka Dog the Bounty Hunter, 61, says he is on the hunt for the MMA fighter.

“This guy did a terrible, horrendous thing to a woman. And there is so many people who I can't believe on social media who thought she deserves this. And I was thinking, wait a minute, these kids -- these younger guys -- need to realize and be taught that you don't hit a woman,” Chapman told MMA Mania earlier this week. “I am a husband and a father. Anytime any kind of girl is beaten like this by any kind of man -- and he's been on the run -- he enters into not an MMA ring, but ‘Dog’s Ring.’”
