MILLEDGEVILLE, Ga. — The college student who accused Pittsburgh Steelers quarterback Ben Roethlisberger of sexually assaulting her said she didn't try to fight him off because he appeared to anger easily.

"I noticed throughout the night he kind of had like a short temper, like he would get really, like, defensive," she told police in her second interview with them on March 5, about 12 hours after she said the assault took place. She didn't elaborate further on what made her think the quarterback had a short temper.

The accuser's interview is among more than 50 audio and video recordings released Wednesday by the Georgia Bureau of Investigation. The prosecutor determined there wasn't enough evidence to warrant criminal charges after the investigation concluded, and he said the woman ultimately asked him not to prosecute the quarterback.

One of the new videos shows Roethlisberger smiling, giving people high-fives and pumping his fist at the club where the woman said she was assaulted.

The quarterback was suspended for the first six games of the upcoming season, though commissioner Roger Goodell said he could reduce it to four games if Roethlisberger shows he is committed to improving his off-the-field behavior.
