My son (age 39) let a friend borrow my car for an hour because of an emergency. His friend did not return car so my son went to get it back, and he couldn’t find this person or my car. This person almost ran over him when he spotted my car at a gas station, but he was unable to follow him. The car has been gone since last Thursday. The police said to send a certified letter to his friend’s house for return of the car after and said to report the vehicle stolen after 72 hours. Can I file a claim with my insurance company in the meantime?
