...and you can bet that whoever was manning the property facility after that seizure - was just buried in paperwork... Along with a copy of the property receipt for each firearm they'd have to have a copy of the NCIC report on each weapon (showing that each was checked to find out if stolen or wanted in another investigation), and an official entry for each weapon into the facility's logbook.... and that's just for starters. None of that would include the various paperwork if an individual weapon was needed for forensic analysis (or to see if any erased serial numbers could be restored....).

The property receipts would be done by the impounding offiicer(s) - everything else would be the property guy's work.... and just to make things even more fun, every item that was needed for court purposes would have to be logged in or out (and after a certain time period - any weapons still in custody would generate a disposition request to whoever impounded it.... and that would get repeated annually as long as they still held the item(s)...). Not exactly the stuff action movies show at all...

I did that sort of work for two years a long time ago and I'll bet the procedures haven't changed much over the years although no two agencies do things the same way...
