"I thought this is how I'm going to die," she said, weeping.
Wilson, a former student and basketball player at Lock Haven University, in Clinton County, Pa., is facing charges of raping and robbing the University of Pennsylvania student and of robbing her Penn roommate inside their Spruce Street apartment on Dec. 19, 2008.
Wilson, who is 6 feet 7, is also being tried for allegedly robbing and raping a woman and robbing, tying up and assaulting her boyfriend during a home invasion of the woman's Center City apartment on Oct. 22, 2008.
In that attack, the victims testified on Monday, a knife-wielding Wilson forced them into the woman's Clinton Street apartment as they were entering.
In both cases, the victims told the jury that Wilson wore a mask, threatened to kill them if they looked at him and fled with cash and valuables.
His defense attorney, Michael I. McDermott, told the jury that Wilson did not commit the crimes and that the victims' failed to positively identify his client.
Assistant District Attorneys Peter Lim and Mark Cipolletti, however, said DNA evidence links Wilson to the victims from both crime scenes. In June, Wilson was sentenced to serve 70 to 196 years in state prison after a Clinton County jury convicted him of raping two Lock Haven University women and assaulting a third.
Wilson allegedly forced his way into the Spruce Street apartment when the rape victim's roommate was leaving to run errands, that roommate testified Tuesday. He robbed and threatened that roommate with a knife and gun until the other woman came home.
Before being sexually assaulted for the first time, the rape victim said her attacker forced her to put duct tape over the roommate's mouth and tie her hands behind her back. He also ordered her to tape her own mouth and eyes.
At gunpoint, he marched the woman out of her roommate's bedroom and around the apartment to collect valuables, she said.
He was a picky thief, rejecting her PlayStation 3 system, laptop computer and her grandmother's bracelet because he believed they were too old, she told the jury.
After the man - reeking of body odor - forced her into her bedroom, the woman said, he attacked her.
"He said, 'You're too pretty to hurt,' " she recalled, fighting back tears. "It was almost malicious," she said of his voice.
"It was then that I knew that something bad was going to happen. I just prayed for the best and that he would not do it to [my roommate] and that he would just do it to me."
