Your talking about Migliore right? Amuso and Casso ordered the hit on Migliore, after his conviction was overturned. Casso cause he was afraid and also had a big ego, and Vic cause he felt Migliore had to have giving something up to beat the 24 year sentence.

On Salvatore Avellino, he most likely did retire cause there has not been a peep of him doing crimes unlike Carmine and others in the crew. That crew has some earners or they might belong to John Baudanza crew.
