Two people with concealed handguns stopped a woman who had drawn a knife inside a Dollar General in Polk County, Florida, and held her until deputies arrived, Sheriff Grady Judd said Wednesday. Natalia Gaviria, 36, allegedly produced the knife and threatened shoppers, prompting a manager to send customers out a rear exit. The pair, one of whom held a permit, pointed their guns at her; Florida law does not require a permit to carry concealed. FOX 13 reported Gaviria is a Colombian national present in the United States without legal status. Judd said she would be returned to Colombia after serving a prison sentence.
