I think that Elizabeth Street address could be in Little Italy? I used to live near there a long time ago. Anyway, sic the mafia on him, that’s the ticket.
Undoubtedly, the mafia members have all registered their guns, so it shouldn't be too hard to find a member of the mob.
It’s pretty near Little Italy. But that part of NYC - unlike Chinatown - is pretty tiny, a tourist area consisting of a couple blocks of restaurants. Don’t think the mafia hangs there.
