If i was robbed at gunpoint for 6,000 dollars, and i know who the person was, should i go to the police and turn him in?

I was putting a down payment on a mustang from a friend i went to high school with. When we met up he told me to bring 6 thousand for a down payment if i wanted the car, which i did. He got in my car and pointed a gun at my face and demanded the money. He got out of my car and in his friends mustang and drove off. I contacted this persons dad via email and basically he told me to F*** off. I am looking for advice on what to do. But i feel like going to the police is a good option.
