The first thing I actually tried was Facebook, Google and LinkedIn type of search engines. With a name like Tony Smith, it makes it really tough and nothing really seemed to match. What makes it more difficult is that all the information that was provided was actually for his girlfriend (address, phone number, etc). I actually "found" her online with the provided address and phone number, but when I tried, it was disconnected. Tried calling the operator and she stated there was no new listing for her. I will try sending a letter to that address as well.
Anyway, I will keep looking. Perhaps Tony will perhaps read this thread...the serach continues.
