If your iPhone is locked and you don’t know its passcode, you can reset your device to erase all its contents and restore your personal data if you previously created a backup. There are three ways to reset a locked iPhone: restoring using iTunes, resetting using the Find My iPhone feature, or restoring using recovery mode.

    Turn it in to the Police. That is someone's phone they could be paying for or payed a lot of money for. Try to find the original owner.
