PITTSBURGH — (WPXI) – A West Virginia woman is facing charges after police say a gun was found in her backpack at a Pittsburgh International Airport security checkpoint. The Allegheny County Police Department says TSA officers spotted a revolver inside a backpack around 10:44 a.m. on Sunday and alerted police. Police determined the passenger’s identity as Amber Brooks, 33, and said she didn’t possess a valid concealed carry permit, so she’s charged with a misdemeanor for carrying a firearm without a license. Passengers who bring guns into airport security checkpoints can also face fines of up to $10,000 from TSA.
