In one of the more unusual investigations of the year, the Warren County Sheriff’s Department set up a sting on a group of people selling vacuums.Sheriff Kevin Harrison said he had received word of a female and two males in a van traveling door to door through different towns selling Kirby vacuums. The group always asked if they could come inside to provide a free carpet cleaning demonstration.While the company that makes Kirby vacuums does conduct door-to-door sales, residents said something about this group’s behavior made them nervous.Harrison explained that many people described a similar scenario: After being let inside, one person would ask to use the restroom, or would reportedly leave for a time. Harrison said homeowners were nervous the individuals were searching for valuables while they were out of sight. However, no crimes have been reported in connection with the group, and they always left legitimate contact information.Harrison used that contact information to set up an appointment under the pretext that he was interested in buying a vacuum. Meanwhile, he had a patrol officer hidden nearby. When the group arrived, they were questioned and their credentials were checked.In a public statement, Harrison said the department had also contacted a second van selling Kirby vacuums, and that both were legitimate.“We have advised them their sales practices are causing alarm. I plan to follow up with a call to their supervisor ... to share our concerns,” Harrison said.The sheriff advised exercising caution before letting unknown persons into a home. He said it is important for residents to call authorities if something seems suspicious. Most of the suspicions about the vacuum sellers had been shared on social media but not reported to the sheriff’s department, Harrison said.“Just because we don’t have a report of a specific incident yet, please remember that numerous residents felt uncomfortable, and suspected these persons were looking and snooping while inside their homes,” Harrison said.Kirby
