I'm late to this thread, but to answer the original question: don't report him. It's none of your business. Protect yourself, your family, and your home, and leave this situation to be sorted out by the Sheriff's department.
You don't have all the facts and what you're relying on seems to be just assumptions and conjecture. It's not your place to intervene. Stay vigilant and keep your doors locked. Intervening could making your life a living hell if this person finds out you were the one who "ratted." My .02, your opinion and that of others may differ.
