What can I charge a person who keyed my brand new truck 8 times and put sugar in the gas tank?

I recently just got my truck and a crazy ex boyfriend drug addict whom I've gotten many police reports against made it pretty obvious he did it. They are checking for fingerprints to process and such, but if they don't find the finger prints, I do have leads because when no one knew he texted me asking about my truck and I played dumb while he basically said no its not then got vulgar. How can I charge him and finally make this menace stop?
