TSA agents discovered two handguns this week at the Sacramento International Airport, an issue it said is a growing problem, which has quadrupled over the past 10 years.
The first incident happened last Friday, when a Texas man was taking a Southwest flight to Nashville. When his bag entered the x-ray machine in Terminal B, TSA officers found a loaded .4 caliber firearm with five rounds of ammunition inside. The man told officers he simply forgot to check it in, according to TSA.
Then Sunday, officers discovered a 9 millimeter loaded with seven rounds. The TSA said the female passenger was heading on a Southwest flight to Washington, D.C., and told officers she forgot to put the gun in her check in bag.
"In these cases, the passengers were able to go on to their flights once they got their checked bags returned to them. Put their firearms in their checked bags," Nico Melendez, TSA spokesperson, told FOX40.
When someone forgets their gun in their carry-on bag, officers are tied up dealing with that person, which makes security lines much slower for everyone else, according to Melendez.
"It's something that happens rather frequently at airports across the country," Melendez said.
Melendez said TSA officers find about seven guns a day, around 2,200 last year alone.
At the Sacramento airport, agents found 12 of those guns over the course of 2014, and have already found six in 2015.
Guns are allowed in checked luggage, typically in locked hard cases, according to Melendez.
Criminal charges for bringing a gun to an airport depend on the District Attorney's offices in each airport's jurisdiction.
However, Melendez said the TSA can file a civil action which can come with a $10,000 fine.
