An Aurora police officer fatally shot a teenager Thursday night who told 911 dispatchers he planned to “shoot up” a gas station and ignored repeated commands to turn himself in.

The incident is the fifth officer-involved shooting by Aurora Police Department officers this year, and potentially the third involving an individual who was not armed, officials confirmed Friday. The department is also currently facing three different lawsuits for allegations of excessive use of force.

The suspect, a white male who officials believe to be 17 years old, initially called Aurora 911 at 7:30 p.m. Thursday, telling a dispatcher that he had a gun in the waistband of his pants and planned to shoot into the area of a gas station in the 200 block of South Havana Street, the APD officials said Thursday night.

About 10 minutes later, police received another call from the owner of the gas station, who told them he locked himself inside the business due to suspicious activity outside, said Aurora Police Chief Todd Chamberlin in a video of his media briefing on the shooting Thursday night. Police arrived on scene about two minutes after.

Around the same time, Aurora mental health officers said they were responding to this incident as well, Chamberlin said. They did not make it to the scene before the shooting took place.

“There wasn’t a huge opportunity to do any kind of crisis intervention in this particular incident based on the need to make sure one, this business did not become an active shooter situation and two, there weren’t any innocent community members who were victimized or about to be victimized by this incident,” Chamberlin said during his briefing.

Officers originally set up on the far side of the station from the suspect, handling weapons including a pistol, a rifle, and a 40mm gun that shoots rubber bullets, Chamberlin said. The teen then began walking toward them with his hands in his jacket, ignoring repeated commands to stop and put his hands in the air.

One police officer fired two-to-four rubber bullets at the teen, but they didn’t do anything to stop him, Chamberlin said. He then began running in their direction, resulting in an officer firing his pistol at the approaching suspect.

The teen was pronounced dead either during transport to or upon arrival at the hospital, Chamberlin said. Authorities could not initially find a firearm on the scene and have yet to say they did as of Friday morning.

The officer who fired his gun has been with the department for “a number of years,” Chamberlin said, and has been placed on administrative leave during the investigation into the shooting in accordance with department policy. The owner of the gas station was taken to police headquarters for further questioning.

The department declined to provide the audio of the 911 call, citing the ongoing investigation into the shooting. The Denver Gazette submitted a Colorado Open Records Act request for the tape of the initial call to dispatch but has not received a response.

“Having done this for four decades, being an officer that gets a radio call that was actually dispatched and called in by the suspect himself, who stated that he plans on basically shooting up a business, that he has a gun and he wants to shoot police officers, that’s a challenging call,” Chamberlin said.

Anyone with information related to the investigation is asked to contact Metro Denver Crime Stoppers at 720-913-7867. Tipsters can remain anonymous and could be eligible for a reward of up to $2,000.
