Should I Dump girlfriend Over Gang Bang Rumor?

I really like my current girlfriend, but I recently heard disturbing news about her. A dude she went to college with says she once "pulled a train" at a frat house, with at least four guys involved. I checked with a girl who also went to school with my girlfriend, and she confirmed that there was talk that this happened. (She mentioned that she was not sure it was consensual).

My girlfriend does not seem like that type, but she has admitted in the past that she was "a little wild" back in college. Should I break up with her? They say a leopard doesn't change its spots. I don't want to be mixed up with someone with no self-respect. On the other hand, if she got roofied or something, I suppose it's not her fault.
