Yeah Serp, in Underboss Gravano speaks on how well respected Persico was on the streets.That he was a "legend" in Bensonhurst. That he always kept his word and was infact one of the few mob guys that was held in such high regard by Gravano. I may be wrong but I believe Gravano said that after the Colombo hit a contract was put on Gallo immediately.And that the next boss made good on that contract or Persico that is.So Persico had the main suspect in the hit killed
