There are wiretaps of Magaddino trying to say Russo was a rat. Maybe he was trying to justify murdering him and it really was about this Commissioon beef?

What's interesting is the timeline for the Valentis. Frank was a Pittsburgh soldier in Ripepi's crew (or even capo by some accounts) but by Apalachin, experts thought his younger brother Costenze was capo of Rochester. Did it go Costenze Valenti > Apalachin legal troubles > Russo > Russo's death > Frank 's takeover?
