A former Arizona police officer has been charged with fatally shooting a man in a wheelchair

Pima County District Attorney Laura Conover said Thursday that former police officer Ryan Remington, who was fired from the Tucson Police Department earlier this year, is due in court next week for a charge. hearing.

He allegedly killed Richard Lee Richards, 61, accused of shoplifting from a Walmart on November 29, 2021.

Conover told a news conference that the investigation into the shooting was led by a “team of former veteran prosecutors” outside of Pima County to help county prosecutors move the process forward.

“Our criminal prosecutors have conducted an initial review to identify other aspects of the incident that require further investigation to bring justice to this case,” Conover said. Early in the summer, it became clear that we were going to start inviting a grand jury to pursue criminal charges.

Remington’s attorney, Mike Storey, told Arizona Public Media that his client will plead not guilty. He also described the case as preposterous and said Remington would appeal the termination of his sentence to the police department.

The victim was shot in the back and in the side

In a statement at the time, Tucson Police Chief Chris Magnus said at the time that an employee called Remington at the Walmart location in November to report a suspected theft from a store.

Magnus said Remington joined a Walmart employee in the parking lot and followed Richards as he “tried to get his cooperation.”

“According to the employee, he met Mr Richards outside as he ran out of the store and asked to see the toolbox receipt. Instead of presenting the receipt, Mr. Richards waved a knife and said, “This is your receipt. “

It is alleged that Richards refused to comply with Remington’s orders to hand over the knife and continued to drive through the shopping district parking lots.

“According to the Walmart employee, Mr Richards said, ‘If you want me to pull the knife out, you’re going to have to shoot me. “”

Later, after Remington relayed the situation over radio communications, a second officer arrived on the scene.

Magnus said at the time that the two officers were a short distance behind Richards when they warned him not to enter another store.

Video released by the Tucson Police Department shows Richards beginning to walk into Lowe when Remington tells him, “Don’t go to the store, sir.”

Seconds later, the officer shot Richards nine times in the back and in the side.
