I have had several friends who had cars stolen, with minor variations they all followed the same pattern.
1. Except for 1 were all stolen from a private parking place. The 1 was idling outside while the owner ran into a store to pick up something already paid for and waiting for them. (Less than 1 minute in the store, came out to see the car driving away.)
2. All vehicles taken to a secluded location and stripped of EVERYTHING that could be removed.
3. All vehicles were up on blocks, apparently to make removal of rims and tires easier.
4. All thefts immediately reported to police / insurance companies.
5. All owners advised by police and insurance companies to keep checking tow lots, in particular city impound lot.
6. All communication with police, insurance, tow lots/companies, city impound totally denied any knowledge of any events.
7. With various devious means, (some likely illegal), all but 1, owners discovered the remains of their vehicles in the city impound lot. The one vehicle was found in California 1,500 miles away, 3 months after theft. The insurance company negotiated (threatened the owner), that they would force him to accept the stolen vehicle, but eventually gave up and let him keep the replacement that they had provided.
8. After reporting to insurance company that vehicle was in city impound lot and up to weeks of denials and threats of legal action, before admission that, yes the lot had the missing vehicle.
9. Evidence indicated that ALL vehicles taken to the impound lot were initially pulled off the blocks with a chain on the bumper.
10. After coming off the block and being drug a short distance, the bumper was pulled off the vehicle and placed on the rear seat. All but 1 vehicle was then towed on its wheels, by a chain around the rear axle, until it reached the impound lot. On one vehicle the rear axles and differential were pulled off the vehicle and placed in the trunk.
11. In every case the impound lot denied possession of the vehicle until pressure of threats of legal action by the owner and insurance company forced them to admit they had the vehicle and release it.
12. All vehicles were declared total damage by insurance company, although in no case was there any damage apparent by the thieves. Quite the contrary, all parts removed were done carefully to avoid damage to the vehicle and the actual damage to the vehicles was solely done by the tow services.
