A prom dress sale at a Georgia gas station erupted into chaos when the seller was ambushed by her former friend and two others. Surveillance footage shows one suspect putting the 18-year-old victim in a chokehold—only to be flipped and slammed onto the pavement. Gwinnett County police arrested Morgan Flinchum, Lelia DeJager, and Kaylee George after reviewing the footage. Flinchum and DeJager have been charged with battery and theft by taking, while George faces theft by taking charges. Police urge buyers and sellers to meet in safe, monitored locations to avoid similar incidents.
