I am a 26 y/o male that was like a older brother to a now 16 y/o female. Our families had a falling out and we havent talked for a couple months. She is being vendictive and recently made up a story saying that we use to make out and tried to have sex. She's saying it happened when she was 13. Nothing happened between her and I and really none of us have any evidence to prove anything, just her word against mine. What kinda trouble could I be looking at? And what steps should I take (get a lawyer, contact DA)?

Thanks in advance for any info

It would be in your best interest to seek advice from a private attorney who specializes in criminal law. The DA will not be looking out for your best interests in a situation like this. If a report is filed against you, speaking to the DA without first being advised by an attorney or without an attorney present may work against you, especially if they are investigating you.

If a report is filed and the allegations are proved false, she can be charged with filing a false police report which is a serious offense. False police reports are generally look upon very seriously by judges. It could also opens the door to a civil suit if damages are suffered as a result of the false police report (i.e. job loss, wages lost, jail time, etc...) Ultimately, her parents may be held responsible given that she is a minor.
