I believe he did it but I doubt he was in his right mind. Then again I could be wrong. All my grandparents or great grandparents who went out in their 90s were pretty mentally sound beforehand except for one so who knows.
But to anyone assuming because this is the first time he's being accused this behavior must be due to senility..... There's a chance that any women he harassed in his heyday are long dead or too senile to come forward. Or just don't care to.
The reason a lot of these older chicks aren't coming out with their stories (and we all know they have them) is because they're from a different time and they feel funny about putting all their business out there like that.
My grandmother was an actress (very small time) and nightclub singer in the 50s and 60s, and my mom was a model in the late 70s and 80s. They both have plenty of stories about harassment and abuse far worse than this (my mom had an incident with Russel Simmons in the 80s for one) but neither would ever dream of speaking on it publicly now because that's not how they were brought up.
