Yes, the department holds an annual bicycle auction generally in May. This year though, I am told that the auction may be delayed until June. We have always shared the date, time, location, and other information with the local media beforehand so that it can be released to the public. This year, I hope to have the information posted on the department's website as well.
Bicycles are not the only items that are auctioned. In the past, lawn equipment, tools, and electronic or household items have been offered at the auction as well. You are correct though, the majority of the items that are seized, confiscated, or found through investigations, and that the department is unable to return to its rightful owner, are auctioned off at the following two sites:
I am glad to hear that you and your father enjoyed yourselves. The clerks in the property room invest many hours and much effort in organizing that event, and officer Michael Joyner is an excellent auctioneer.
See for yourself:
As for the decommissioned squad cars or vehicles, they are auctioned off via the Indiana Auto Auction.
Thank you for the post.
