That is not going to come into this trial. It would be excluded by the rules of evidence for multiple reasons.wtf. i haven't been paying attention to the trial. weren't there dozens and dozens of people who came forward?
The prosecutors probably only had the word of the victim. Remember this happened more than 10 years ago.
Keep in mind that it can be hard to get a rape conviction even when the case is brand new. On an old case like this it was always going to be really hard to get the conviction. That is why I am still happy that they brought the charges and went forward with this.
