Paul Mason, Chief of Police at Lambert, said police were called to the concourse around 6:20 p.m. after airport screeners found a prohibited item in a bag.
When airport police and TSA security officers arrived a few minutes later, the individual and the bag were gone. Mason said the item appeared to be a double-barreled derringer handgun.
I'm confused... If the TSA saw a double-barreled handgun in the x-ray machine, why exactly would they allow the person AND the bag to just continue on his/her way, without even getting a good description of the bag's owner?!!?! (On the news report, the police chief told the news anchors that the TSA was unable to get a good description of the person, so they couldn't find him/her)..
