I think he was guilty.
I saw a movie about it some time ago and they showed that she was murdered by a Black man.
One of the girl’s relatives studied the case for some time and eventually concluded that Franks was the murderer.
The evidence seems to point to the janitor. Most historians believe it was him I believe.
Were any Jewish folks involved in the making of the movie? It’s always been a big issue for New Yorkers of that faith; Frank wasn’t your typical Southern Jewish businessman. Those folks tended to be highly assimilated, unlike the carpetbaggers.
