I have been emailing and chatting with someone for several weeks.He was working in Dubai and lives in VA.I have not heard from him in 4 days we talk several times daily.Also I get no answer from his phone. I'm worried something has happened to him. I have his email add. His name and date of birth

Just a quick question.

If you have their email, why not send them one? :confused:

You can not find out who they really are though the Yahoo address. ( well short of a police warrant, to search IP address used to sign into Yahoo, and then match up the time of online to usage if they are using a service like AOL.
Of course if they are using a public domain, coffee house, library or something similar, you can't even search that at all.

Please do not start several threads with the same question, I have merged your posts.
