The absence of evidence is not proof of fabrication.
Edit to add, this could easily be a Lewis Brinson situation, where it sure seemed like a Rockies fan was yelling the N word at Brinson while he was at bat... until we realized he was shouting at Dinger, the Rockies' mascot.
Just because they didn't find evidence doesn't mean she lied. She may think that's what she heard. She may be right, she may be mistaken, and she may be lying. We have no evidence to prove any of this.
I actually think this is probably what happened. She thought she heard something that didn't happen.
But considering almost no one else around seemed to have heard it (at least outside the team, I haven't seen anything one way or the other from other team members), it would have been handy if it could have been checked out a little bit more before she's on Good Morning America talking about it and other teams are cancelling games because of something that (likely) never happened.
