I doubt that Adam Marek or Beacon ever used 613 Cross Street as their address since BCND's stuff started after 613 ceased operations as a commercial office provider.
However, if you're referring to 14390 Route 30, let me reiterate what it is. It is an office provider. I am informed there are hundreds of companies there that use the address on official filings.
Now, from reading the posts on BCND, someone said BCND had a REAL office there, not just a virtual office. I don't know.
But you definitely didn't do your DD in that regard. Try routethirty.com or even try the PASOS and see 14390 is an official registered office address. What you're investigating for a tie in is a virtual office, so you're going to find many people and companies tied in. They might not be a real link.
