Should I talk to them if a car that I rented was used in the commission of a crime?

I rented a car twice for a friend because she told me her car was in the shop and needed a car to get back and forth to work. I learned later after the 2nd car was impounded by the police that both cars were used while committing a crime. I had absolutely nothing to do with these crimes. I have learned she has a criminal record. My insurance is being billed for the damages to the 2nd car and detectives showed up at my house to question me.
