Reporter: Former students at Vanderbilt university facing decades in prison for the sexual assault of another student, a 21 year old female. I remember waking up in another room.

Ands they shows glorify drinking and section. They glorify promiscuous sex, acting out, multiple partners.

They claim surveillance video shows the victim being by Vandenburg to his the four allegedly laugh during the assault. Vandenburg is alleged to have passed around condoms to encourage other people to have sex with this woman he was presumably dating at the time. So as a legal matter, even though there's not an allegation, Vandenburg engaged in a physical act of rape that night. The authorities believe his actions, his intentions, his comments, all become rape because of what he was doing and saying that night. Reporter: Vandenburg also taking images of the assault and sending them to his friends and searched online how to delete photos so police couldn't find them.

I do. It was me. Reporter: He went further, apologizing to the victim from the stand. I'm just sorry. I never intended on hurting anyone. Reporter: What was that moment like in the courtroom when Cory bait eye apologized to the alleged victim while he was on the stand? You know, it was kind of a silent moment in the courtroom. My eyes turned to the victim to see how she would react, and she didn't have any sort of visible reaction. She was somewhat still through part of his testimony until she became ill. Reporter: He also testified he was too drunk to remember the incident, after consuming between 14 and 22 drinks that night. What if any recollection today do you have of that event? None at all. Reporter: Beatty saying he didn't realize what he'd done until the next morning, finding graphic pictures on his phone, just as he was on his way to church. I was horrified.

Reporter: But like batesy, the young lady said she had no recollection of the attack. What did she tell hundred happened? He told me that I had gotten sick in his room and he had to clean it up and that it was horrible and that he had to spend all night taking care of me and that it was horrible. Reporter: Testifying last week that she'd been out drinking that night with vamdenburg who she'd been casually seeing at the time before passing out. I felt very out of it. I didn't feel like myself. I felt very confused. I felt sick. I was nauseous. I started to develop a really bad headache, and I also was in pain in certain parts of my body. I was sore all over. Like I said, I was in pain, particularly right knee. I also have a lot of bruises on my legs. And I did notice a few days later that I had bruises on my buttocks.

I have power over you are. Reporter: The national beebt rages about the rapes on campus.
