Katla witnessed it as it happened. I'll pepper it liberally with "allegedlies" because of legal implications and all.

According to what she'd heard/seen, some guy and some girl were having fun play-wrestling on Saturday night and that much alcohol was involved, and that she accidentally had hit him in the eye.

Well, Sunday morning, while I was up getting my vehicle, Katla says she saw the woman walk past the guy and out of nowhere he threw a punch, knocked her down, then kicked her while she was down, then walked away. I didn't see what happened myself; I only saw the crowd (including chirurgeons) around her and him saying "She's fine, I didn't hit her that hard."

I saw the Sheriff's Deputies arrive and take statements, and Katla was among the witnesses to give one.
