If you actually own that vehicle and you have the title, whoever made that call is in deep sh_t. I have never heard of any law in the United States that allows a municipality to tow or remove any personal property from someone's domicile and destroy it without due legal course.
Even if the car was illegally parked, and it was towed, you still have at least 10 days to claim your property from the pound.
Sounds to me like someone there is putting one over on you.
Even if they didn't give you the opportunity to recover it, they would most likely auction it off, not destroy it, unless it were a severe health hazard or something like that.
