Video has been released that shows a gun fight in a shopping centre, which left a man dead and two officers injured.
Police were attending a routine call to remove trespasser Mitchell Oakley from an Arizona Walmart in April, when he opened fire.
CCTV released by Chandler Police Department shows officer Daniel Colwell being shot twice in the chest - knocking him to the ground - as Oakley tries to head for the exit.
The other officer on the scene, Joshua Pueblo, can then be seen sliding across the floor as he attempts to stop the 24-year-old.
As Oakley sprints for the Walmart exit doors, Pueblo shoots and kills him.
Officer Colwell was honoured in September with the ASIS Award for Valor for his bravery during the incident.
“It’s tough you know,” Cowlell told ABC15 after the ceremony, “those moments when you walk out the door, you never know when it could be your last.”
