I don't have any info pointing to that. But traditionally, a capo di decina (which is what Vic Cotroni was), doesn't reach out to a boss of another family, especially one who isn't even in his general territory, but actually in another country like Patriarca and Bruno were.

He needs to go through proper channels and contact his administration. They in turn would reach out to another boss if they even deemed Cotroni's request noteworthy enough.

Thats proper protocol.
