A Colorado teen who was fatally shot by a police officer earlier this month was carrying a pellet gun, not a handgun, police announced Friday as they released body camera footage of the struggle.

Police shot and killed 14-year-old Jor’Dell Richardson, who was Black, on June 1 after chasing him from a suburban Denver store, where he was believed to be involved in an armed robbery with a group of other teens. Aurora police had initially said the teen was armed with a semi-automatic gun, but Chief Art Acevedo corrected that on Friday.

Acevedo said the pellet gun Richardson carried looked like a HK USP 9 mm handgun.

“It is a tragedy because a young man has lost his life,” Acevedo said at a press conference during which body camera footage was released.

Two other 14-year-olds were arrested and charged for the robbery, Acevedo said.

Acevedo said police released the body camera footage Friday because Colorado law requires them to wait 72 hours after the family has viewed it.

What happened that day?

Acevedo said an officer who covers gang-related crime saw a group of teens wearing hoodies and medical face masks headed toward a convenience store. The teens robbed the store of vaping cartridges, police said. Acevedo said at a press conference that Richardson had lifted his short in the convenience store to show the employee the weapon in his waistband.
