This looks like a case of putting the cart before the horse.

The conventional sequence of processing would be more likely to start by
processing a police report. It looks up the car in the documents in the
folder about cars. If there is a match, then perform whatever action is
required, then go onto the next police report until they are all
finished, then stop and wait for more police reports to arrive.
I see no benefit in processing this back-to-front.
