>There was a pile of a couple doors and some wheels that had been confiscated because they were from stolen vehicles.
The assumptions baked into your comment are probably the most Massachusetts thing I've heard all week.
The yard just has to check that the vins match the paperwork and that you match the name on the title.
Doors aren't serialized (models that put vehicle info on the driver's door not withstanding). Wheels aren't serialized. Those were sitting there because some employee wanted them, either for personal use or to sell.
