In NJ and most other jurisdictions, you are potentially subject to being charged with Filing a False Report and False Swearing charges. The problem you will now face is that by making these statements, you have become a witness for the State which will place you in the position of needing to either commit another crime (perjury) when you are called to testify at any court proceeding; or, of needing to assert your constitutional right to remain silent. Under either of these scenarios, you need to consult with an experienced criminal defense lawyer admitted to practice law in MD as soon as possible.

This answer does not constitute legal advice, create an attorney-client relationship, or constitute attorney advertising. I urge you to immediately contact an experienced criminal defense lawyer admitted to practice law in your State before you make any decisions about this case.
