My roommate repeatedly took unauthorized use of my vehicle. He has no license due to a DUI.
I am building a case against my roommate without a lawyer. What statements/affidavits should I bring to court with me to prove that my roommate repeatedly used my vehicle without my consent? So far I have signed statements from locals stating when they witnessed it parked at his work place or on the road while I was out of town. He is pleading guilty to unauthorized use but I would also like to press charges for damages resulting from bad gas he stole from my landlord and then used in my tank, as well as theft of a controlled substance medication which I am prescribed that went missing from the vehicle during his unauthorized use. When he was initially arrested I neglected to tell the officers about the gas or medication and he is denying both.
