Hi your first step might be to check the Aurora archives for last night.

Jim he is obviously a first time poster with no premium membership. I don't think checking the archives is an option for him.
Imagbee64, Let me be the first to welcome you to radioreference.com and the Colorado Forum. Can you give us a little more information as to what you saw/heard? Maybe someone was listening or someone has a premium membership and can check for you?
For further reference, if you do live in Aurora (or pretty much any other part of the state for that matter) you can listen to PD/FD/EMS communications online. Just click on the "live audio" link above and follow the map to listen to your desired agency.
Either way welcome!
