By By Paul Bright Mar 26, 2012 in Crime Sacramento - TSA officials in Sacramento found a loaded handgun in a man's carry-on as he tried to board a flight towards Phoenix. That handgun was just the tip of the iceberg. "Waller was booked on charges including unlawful possession of a loaded firearm, unlawful possession of a concealed firearm, possession of an unauthorized weapon in a public building and possession of a firearm within a sterile area of an airport," Sacramento Sheriff's Department Deputy Jason Ramos said. Waller is being held without bail. Sheriff’s officials also inspected his vehicle, which parked at an off-site location. They found eight more loaded guns, almost 200 rounds of ammunition and three knives. Harold’s mother, Helen Waller, told KPAX news in Missoula,Montana that he was suffering from mental illness and had been exhibiting abnormal behavior after his divorce. "Then it just kind of got to the point where he was not thinking logically anymore and his thought process was all messed up," said Helen Waller. The Transportation Security Authority at the Sacramento International Airport may have prevented a shooting incident when they spotted firearms on a passenger during a security scan. According to KCRA news in Sacramento, officials took Montana resident Harold Waller, 45, into custody after discovering a handgun in his carry-on luggage. A further search on Waller discovered a loaded gun with a round in the chamber on his person and three more guns in his luggage.
