The video, released by the Tucson Police Department, shows the fatal confrontation between Officer Ryan Remington and a man in a wheelchair. The man, identified by police as 61-year-old Richard Lee Richards, was in a motorized wheelchair at the time and had brandished a knife, but had his back to the officer at the time of the shooting. The incident occurred when the Walmart employee noticed Richards leave the store without paying for a toolbox. The employee followed Richards into the parking lot and asked if he had a receipt. Richards then waved a knife at the worker and said: “Here’s your receipt.” Donate to PoliceActivity: https://www.patreon.com/PoliceActivity Like us on Facebook: https://www.facebook.com/PoliceActivity Follow us on Twitter: https://twitter.com/Police_Activity
