LAS VEGAS -- A man who changed his name to War Machine as a mixed martial arts fighter has pleaded not guilty in Nevada to charges that he tried to kill his porn star ex-girlfriend and her friend.
A Clark County judge heard the plea Thursday and set trial Feb. 17 for Jonathan Paul Koppenhaver on 34 felony charges including attempted murder, sexual assault, battery and coercion.
The 33-year-old remains jailed and could get life in prison if he's convicted.
Defense attorney Brian Watkins declined to comment.
Koppenhaver is accused of letting himself into ex-girlfriend Christy Mack's home with a key early Aug. 8 and attacking her and her friend Corey Thomas.
The Associated Press usually doesn't identify alleged victims of sex crimes, but Mack has agreed to let her name be made public.
