I'm not entirely sure what you're asking. Malicious Mischief 2 is a class C felony, so it's significantly more serious than your previous MM3 conviction. What your penalty might be depends on a lot of factors, including whether you have any other criminal history. If the prosecutor has charged you with a crime, you should have the opportunity to screen for a public defender. If you are ineligible for a public defender, I would recommend that you hire a private criminal defense attorney. Whether you have been charged or not, I would recommend that you speak to an attorney before speaking to the police any more about it AT ALL.
