15yo son stole my car and crashed it in the driveway. Want to report him to the police.

Location: Oregon

Yesterday I took a short day trip out of town with my GF, and my 15yo son refused to come with us. I came home in the evening to discover my car moved and with a smashed rear bumper. He admitted to trying to take it on a joyride but crashed into our fence before even making it out the driveway. He has no learners permit and has never been behind the wheel before.

Normally I would think this should be an issue dealt with personally, but my son is completely out of control. He is smoking weed everyday and taking most any other drug he can get his hands on. He is openly defiant and does whatever he wants. He steals from me any chance he gets, and this was a big oversight, leaving my spare key in an unsecured area for the day. Any resistance to his behavior is met with, “fuck you, you fucking bitch”, and even violence when he feels it will get him what he wants. Just a couple weeks ago he was taken by EMS to the ER with a 0.21BAC after passing out an vomiting at the city bus station, then tried to fight the hospital security staff, accusing them of stealing the backpack he actually lost while wasted. He even ran away all of last summer because he refused to follow basic rules like a reasonable curfew. He recently spent three months in psychiatric hospitals and group homes but is already right back to this behavior.

So anyway, I’m at my whits end. I want to call the police to report this. What can I expect as far as charges? I’m worried he will end up with a bunch of fines that I’ll be responsible for paying, which absolutely sucks since I already have to pay out to repair my car. Thanks
