and...this might be the last for a bit both lapresse and journal de mtl link barberio to marco pizzi which could make sense.
but the articles make it sound like barberio is under pizzi in the pecking order.
marco pizzi has been identified as a cell leader of his own so the confusion is easy to understand and at times very frustrating.

as far as mirarchi being the instigator of this i would say no only because as i have stated before the very fact that he is alive after his dec 2017 release would prove either he is very well connected or indeed as most media have stated he has made a truce with current leadership.
