About 3 month ago my wife left her laptop at ORD, i was on a flight about 4 hours later (long story but one of us needed to get home earlier) ... get a frantic text that she went to take out her laptop and it wasn't there. I run from my gate to head to TSA. Find someone at the TSA to help - fully expecting to have to present ID, prove that this lap top is somehow mine, eg log in or similar.
When the gentleman helping me and I get to the desk where they store this stuff (just off to the side in T1 ORD) he opens a drawer and basically lets me look through it for her 15" retina mac book pro. Found it and asked if he wanted me to log in to prove it was her machine. Nope .... just let me walk off with it. So if they don't have your machine perhaps you can find a nice replacement.....
