It's easy for agencies to lose radios. I had a radio lost by a DA investigator earlier this year when courts were closed. He didn't know the radio was gone until July when courts started to "open up" and at a roll call noticed his radio missing. He reported it immediately. Ironically, it sent an EA around May 14th at 1930 hours. Our center did NOT report this to radio support so we didn't know. TLDR version, radio was picked up by a citizen who took it to a pawn shop. Pawn shop held it for 90 days and sold it on Ebay. At the time, since it wasn't in GCIC/NCIC as stolen, the pawn shop's submitting their pawn record to the AHJ got nothing back on it. Nevermind it had "COUNTY NAME" on the radio alias and the pawn time matches when we got the EAs, but it was gone and sold across the country.
We were able to recover the radio as Ebay cooperated fully with the LE agency involved. Buyer got their money back thru Paypal. What was interesting is the buyer (or whoever they took the radio to) bypassed our codeplug password with depot software and the radio had all kinds of systems in it. Needless to say, the buyer didn't answer my calls to ask them how they did what they did. The one who stole the radio got two felony cases for felony theft of lost/mislaid property and interference with governmental administration pending. Pawn shop loaned $40 on it.
Beware eBay APX radios. Always use a credit card funded PayPal if you do to protect yourself. O/P, search Ebay completed auctions...you may be surprised.
