But when he killed Colletti without Riina's sanction, Riina ordered the murder of everybody involved and they were all Cosa Nostra figures. I mean, in all books I read Lauria was indicated as an enforcer for Cosa Nostra, even though I don't know if he was made.
I haven't read any mafia book ever so I don't know what you read or from where. Lauria did kill Colletti but Lauria was part of Stidda when Riina went to war and killed him.
