If you could supply more information about Ben it might be helpful for anyone that may have information. Information such as how old he was when he disappeared, his ethnicity, obvious scars or distinguishing characteristics, did he wear glasses, what color are his eyes, etc. would help in identifying him now years later. Also, what can you say about the events that lead to the disappearance. Only giving his name and the fact that he disappeared 11 years ago really doesn't help much.
Good luck in your search.....
