just my educated guess what ever persico is calling shots today relieved sonny of the underboss position when he was sentence to 8 yrs back in 2011. probaly took a few years but id bet theres been a new underboss for awhile. wasnt benji the claw the underboss for andy russo, hes probaly is again or someone from the persico family tree. im sure sonny is highly respected but you cant have the offical underboss in a assisted living home or whatever its called. theres way to many younger guys think about it.the feds just either dont know or dont want to state it to the public yet. till the next indictment
