erasmo crivello has been alleged to be working w/ marco pizzi since there dual arrest in proj clemenza 3 2016.
its possible the 2 worked together going back to 2013 under tonino callochia in cocaine trafficking.
there appears to be 2 sides of crivello family in mtl one of which has no mafia links.

i agree that mirarchi runs his own cell...i am also coming around to the theory that the mafia in mtl has become a lateral structure not a classic top down admin.
mirarchi had an almost direct link in 2011 to cocaine coming from the sinaloa cartel out of LA. that was a long time ago now i know but mirarchi has strong connections and clearly commands respect in the milieu.
