Calautti was involved on the hit on Panepinto in retribution for Panepinto whacking 2 Ndrangheta guys who were running vending machines in his territory. These 2 guys were Calabrian and protected by the Siderno group. Odds are pretty good that Calautti is with the Ndrangheta. When the Siderno group went to Montreal for answers on the loss of their 2 guys, Vito washed his hands & the green light was on for the hit on Panepinto. So, I doubt it is payback from Vito. More likely some Siderno internal housecleaning.
