You Cant Trace Down Who Did it Only Facebook Admin and the Police Can Do That Even if you Got There IP Address That Would Only Give you the ISP Internet Service Provider and the City and State Wont Tell you the Address or Specific Information

If it Was Registered Under your Email Address You Can Close the Accounts Tho

you Wont Have the Password But Hit Forgot Password and you Can Use your Email Address to Pull Up The Account Information and Be Able to Get Into the Account
