Can I throw her stuff in the fireplace?

I was dating this girl for 2 weeks and she left some of her stuff here like some DVDs, shampoo, lingerae, and a pair of heels. She lives about 30 miles from me and I broke up with her last night. She is texting me telling me to bring her all of her stuff or she will call the police. I told her she could come and get it but she can't because she doesn't have a car. Can I just throw her **** away or do I have to save it for some period of time?
