Since @Rush reminded me about the situation....interesting to note is that when Scalise and Rachel managed to steal the Marlborough Diamond and the rest of the jewels from England, later the whole stash was never recovered. Some reports say that Scalise has mailed the famous diamond to New York, where it was allegedly “welcomed” by Scalise’s sister. Sources say that the robbery mightve been an Outfit-sanctioned job, and that the precious loot has ended up in the hands of the Cicero-Chinatown group but I also believe that both Scalise and Rachel never saw a dime from the stolen loot. So it is possible that was the main reason for which Scalise decided to "invade" the LaPietra home, decades later, believing that the diamond and other jewels were still in some safe somewhere in the house.
