im all for chasing people down, just be careful when it comes to Brooklyn NY, NYC, etc , make sure you know who you are dealing with first..
No mailbox no office no coin bet at 101 just a marketing scheme , my attorneys in that building
These scammers surely never ever lived at park avenue

Probably it is just some mailbox address.
You should find out who rents those mailboxes and give them a call.
Actually I think the vincent digiovanna guy might work in that building... someone may want to chase that one down. I think he's the US/NY connection here. Can your attorney find out?
Address belongs to 50 story office building. Might not be a fruitless adventure...
