That's completely different though because the parents weren't the one accusing LL of the crime. Their statement would have been made after they'd been told of the allegations. So it would colour her judgement completely.
Actually you don't know when their statements were taken. It might have been before the first arrest. In which case they wouldn't have known she was suspected.
There are
grape victims who only contact the police to report a historic
grape because the police are asking for more information about a certain person charged or because they see it on the news. Or years later when they feel ready to talk about it. Child sexual abuse can be prosecuted years later as well when children are adults and ready to report.
As standard, we don't go around doubting the victims of a crime (like the parents are) and their memories. I think you would be grateful of it if you are ever the victim of a crime and only remember details after a time has passed, or a suspect has been arrested, once you've had a chance to settle your mind,
