I am desperately searching for an old friend of mine named Robert Stark. PLEASE HELP!!!!!!!?

I have tried all the sites that help you look people up, and i have had no luck. His name is Rob(ert) Stark and should be about 31. He used to live in missouri, but may also be living in England. He's tall and skinny with brown hair and blue eyes.... If any one knows where or how i can find him please help?!?!??!!?!?
