Early on in his underworld career, Dominick Trinchera seems to have been affiliated with members of the Colombo Family, including their 1971-1973 era consigliere Joseph (Joe Yak) Yacovelli. He took a contempt arrest with other Colombo members during their internal civil war after he was among a gaggle of soldiers and associates subpoenaed to testify before a grand jury probe.
He later became close to members of the Bonanno clan. In later years, this is where he would make his mark, becoming an inducted soldier. Within a few years, Trinny was elevated again to the post of “capo di decina” for the Westchester area.
