The third day of the beating and sexual assault trial of former MMA fighter War Machine is over after Christy Mack took the stand. Mack testified about the months of abuse at the hands of her former boyfriend, Jonathan Koppenhaver. Mack told jurors the abuse got worse and she feared for her life. Koppenhaver faces nearly three-dozen charges in the August 2014 attack on Mack and her friend Corey Thomas.
