That's interesting pmac.
Furio, I actually did hear/read all the names you mentioned, just coundn't recall them or locate them.
In many retellings of the event, right before Galante is hit, one of the hitmen yell "Get em Sal!"
Could it be that one of the above mentioned hitmen was nicknamed Sal? Or maybe Salvatore was a middle name? Witnesses heard the Get him Sal statement, but that could have been to throw off the audience, since everyone had a mask on.
