Adult performer Christy Mack on Monday night released a statement and disturbing photographs detailing a vicious assault by her former boyfriend, cage fighter Jon "War Machine" Koppenhaver.


Mack, 23, and another unnamed individual suffered "severe but non-life threatening injuries" on Friday after a domestic dispute with Koppenhaver at Mack's home in Las Vegas, police told the Las Vegas Review-Journal.

Sunday on his Twitter account, Koppenhaver wrote that he "will always love" Mack and claimed he was planning on asking her to marry him. Koppenhaver suggested he attacked his ex-girlfriend in self-defense, writing that he "ended up fighting for my life."

In her statement, Mack said the vicious attack occurred after Koppenhaver broke into her home. She said Koppenhaver forced her to strip, beat her, stabbed her, and cut off her hair.

"At around 2 am Friday morning, Jon Koppenhaver arrived unannounced to my home in Las Vegas, NV, after he broke up with me in May, he moved out of my house and back to San Diego. When he arrived, he found myself and one other fully clothed and unarmed in the house. Without a single word spoken, he began beating my friend; once he was finished, he sent my friend away and turned his attention to me. He made me undress and shower in front of him, then dragged me out and beat my face. I have no recollection of how many times I was hit, I just know my injuries that resulted from my beating."

Mack described her injuries, and the assault that caused them, in gruesome detail.

"My injuries include 18 broken bones around my eyes, my nose is broken in 2 places, I am missing teeth and several more are broken. I am unable to chew, or see out of my left eye. My speech is slurred from my swelling and lack of teeth. I have a fractured rib and severely ruptured liver from a kick to my side. My leg is so badly injured I have not been able to walk on my own. I also attained several lesions from a knife he got from my kitchen. He pushed the knife into me in some areas such as my hand, ear, and head. He also sawed much of my hair off with this dull knife. After some time, the knife broke off of the handle and continued to threaten me with the blade. I believed I was going to die. He has beaten me many times before, but never this badly."

Mack said that Koppenhaver had threatened to rape her. She was able to flee to a neighbor's house when he left the room.

"He took my phone and cancelled all of my plans for the following week to make sure no one would worry about my whereabouts. 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. He left the room and went to the kitchen where I could hear him ruffling through my drawers. Assuming he was finding a sharper, more stable knife to end my life, I ran out my back door, shutting it behind me so the dogs didn't run inside to tip him off. I hopped the fence to the golf course behind my house and ran to a neighboring house. Naked and afraid he would catch me, I kept running through the neighborhood knocking on doors. Finally, one answered and I was brought to the hospital and treated for my injuries."

During an interview last year, Koppenhaver joked that he would murder Mack if the couple ever broke up, TMZ reported. He also joked about raping his girlfriend on Twitter.

Police are still searching for Koppenhaver, who has fought in the Ultimate Fighting Championship and Bellator. He is wanted for two counts of battery with substantial bodily harm, one count battery resulting in substantial bodily harm, one count of battery by strangulation, one count of open and gross lewdness, one count of assault with deadly weapon, and one count of coercion/threat with force.

Mack said in her statement there was a $10,000 reward for the capture of Koppenhaver.

Koppenhaver previously served prison time for an assault in San Diego. Bellator terminated his contract on Sunday. The UFC terminated his contract in 2008.
