Harrowing footage caught the moment an off-duty Arizona cop working as a Walmart security guard shot a 61-year-old man in a wheelchair nine times in the back, killing him — after the disabled man allegedly shoplifted. The officer, Ryan Remington, was on assignment at the Walmart in Tucson on Monday when an employee alerted him about 6 p.m. that a customer in a motorized wheelchair had swiped a toolbox, KGUN reported. The employee caught up with the suspect, identified later as Richard Lee Richards, and asked him to show a receipt in the parking lot. “Instead of providing the receipt, Mr. Richards brandished a knife and said, ‘Here’s your receipt,’” Police Chief Chris Magnus said in a statement, according to CNN. The chief said Remington, a four-year member of the Tucson police force, also followed Richards while “attempting to gain his cooperation” and surrender the blade. #Police #Shooting #Murder The New York Post is your source for breaking news, news about New York, sports, business, entertainment, opinion, real estate, culture, fashion, and more.
