Defamation of Character

My sister filed a report on me for breaking and entering, stealing her Vicodin. This supposed incident took place while I was at dog school with several witness'. I have substantial alibies for my whereabouts, including stamped ATM and gas reciepts. The real issue is that when I read the Police Report, I about croaked! She stated in the filed report that I was a Vicodin addict(I have NEVER taken Vicodin)also stated that I was in and out of Rehab centers. She told the reporting Officer that I had been kicked out of the last rehab stint! I HAVE NEVER BEEN IN A REHAB CENTER OR BEEN PRESCRIBED VICODIN!!! I have never been hospitalized for an addiction problem and everything in this report can be proved as lies. Now I am informed this is Public Record! What do I do? How do I get this falsified info expunged? I'm feeling like I'm in a bad Lifetime Movie! HELP!!!
