Jonathan Paul Koppenhaver's leg shackles rattled softly as he sat, bouncing his left leg steadily beneath the defendant's table, while his ex-girlfriend, Christy Mack, testified she feared he was fetching a knife to finish her off when she ran bruised, bleeding and naked from her house and knocked on neighbours' doors for help early Aug. 8.
Mack testified she remembered tasting blood when she came to on the floor of the running shower, and a kick in the abdomen sending her back to the bathroom floor when she tried to get to her feet.
"I couldn't breathe," she said. "I don't remember getting out of the shower. I just remember being on the floor. Naked on the floor. Cold."
Mack sobbed as she viewed photos of her injuries including a broken nose, missing teeth, fractured eye socket, leg injuries and a lacerated liver. She said she had cut marks on her head, and remembered Koppenhaver inserting a knife in her ear while threatening to kill her.
That knife broke as Koppenhaver cut her hair and wigs, she said. She decided to flee when she heard Koppenhaver in the kitchen rummaging through drawers for another knife.
"I shudder to think what would have happened had she not escaped," Las Vegas Justice of the Peace Melanie Andress-Tobiasson said minutes later.
Koppenhaver laughed audibly and shook his head at one point as prosecutor Jacqueline Bluth asked Mack details of alleged sexual attacks.
Defence attorney Brandon Sua tried to deny his client laughed, but Andress-Tobiasson stopped him short.
"I watched him," she said.
The judge added two felony charges to 32 previously lodged against Koppenhaver and bound him over for trial on charges also including coercion, burglary, attempted sexual assault, preventing or dissuading a witness or victim from reporting a crime, and strangulation.
Koppenhaver didn't testify Friday. Sua said he'll plead not guilty at his arraignment Thursday in Clark County District Court.
The Associated Press usually does not identify alleged victims of sex assault, but Mack agreed to the use of her name in this case.
One new charge, sexual assault, alleges Koppenhaver raped Mack one more time than previously alleged.
The other, felony battery causing substantial bodily harm, stemmed from Koppenhaver's alleged attack on Corey Thomas, a computer shop owner who was staying the night at Mack's house when Koppenhaver let himself in with a key, and found them in her bedroom after 1 a.m.
Thomas testified he suffered a broken nose and a dislocated shoulder.
Mack testified she and Thomas were friends, not in a sexual relationship. She said he was helping her set up a booth at a tattoo convention where she was registered appear the next day.
The judge also heard muffled sounds of a struggle and screams recorded after Mack dialed 911 and left the phone line open. Mack testified that Koppenhaver was attacking Thomas at the time.
"Jon. Stop! Please stop!" a woman's voice says.
Koppenhaver finally let Thomas leave the house, but Mack told Bluth she felt she couldn't leave.
"It would have been much worse if I had tried," she testified.
The 23-year-old, whose legal name is Christine Mackinday, sobbed and dabbed her eyes with a tissue during several hours of testimony.
She made a brief statement to reporters as she left the courthouse with her lawyer, Daniel Albregts.
I'm glad things are coming out, in there and in the media, about domestic violence and domestic abuse," she said.
Koppenhaver, who also has acted in porn productions, was arrested Aug. 15 at a hotel in the Los Angeles suburb of Simi Valley. He was dropped by his fight promoter, Bellator MMA, after Mack's accusations were made public.
He made his Ultimate Fighting Championship debut in 2007 and lost his only pay-per-view bout in 2008. He had a 14-5 record as a welterweight and last fought in October 2013.
