A Missoula woman has been arrested after authorities said she brandished a gun at her downstairs neighbors, who were celebrating their twins' birthday by playing video games.
The Missoulian reports Debra Kay Knox appeared in court Monday on three counts of assault with a weapon.
Deputy County Attorney Jessica Finley said in an affidavit that police responded to a report of a woman in a nightgown knocking on a neighbor's door with a gun.
The family inside, including three children, was playing a video game that involves jumping around.
A woman at the residence said the 55-year-old Knox said she worked for the FBI.
The affidavit says Knox told officers she went to quiet her neighbors and used the gun to get their attention.
She is being held on $10,000 bail.
