Well holy canoli, this might not have the best intentions backed by it. You can do people searches online, if you are willing to pay for it.
But folks, take it as someone who knows. Some psycho internet stalker pitched very much the same speel to get information on where my mother was living a few years ago... the goodhearted people helped him, JUST so we could renew the restraining order.
There are reasons some people wish not to be found. I'm not saying the OP is nuts. I'm saying..the government provides secure services for those that wish to extend the effort to look for someone for valid reasons, that way when it backfires,
you didn't aid in helping someone do something they shouldn't be and brought in as an accomplice to a crime... the insured company is.
Everone strap your thinking caps on!
...this belongs in the "PEOPLE SEARCH" forum by the way.
