Property damage can have both civil and criminal consquences. If you are criminally charged, hire a criminal defense attorney. If you are sued in civil court, hire a litigation attorney to defend you.
Until you know what claims are being made, you cannot begin to understand the range of potential punishment(s).
To charge you with obstruction of justice the state would have to prove that you knew the name of the person, and gave the police false information. Everyone has the right to refuse to answer police questions, but if you choose to answer, you can be charged if you lie.
