i found iPhone 6,how i can find contact to this person? Can anybody help me?

Take the iPhone to the nearest police department. Let them deal with it.

Just so you are aware, this is a user to user community. You are not communicating directly with Apple here. Volunteers reply to discussions.

So no one here can help with locating the owner. Sorry !!

I think it's very admirable of you to try and locate the owner.
