Police released new details and video related to an Oct. 3 shooting by police of a man who appeared to be armed with an assault-style rifle in northwest Aurora.

The man, identified as Kory Dillard, 37, was fatally shot by an Aurora Police officer after an apparent attempted robbery in an Aurora apartment parking lot prompted numerous 911 calls about a man “waving around” a gun.

The video comes two days at Channel 7 News reported the Dillard’s family said they will file a wrongful death lawsuit against the city.

Police said the shooting began at about 1:30 p.m. when a resident at Brent’s Place, on the 1600 block of Oswego Street, called police to say two men outside in a parking lot were fighting, and one appeared to be armed with an assault-style rifle.

Police Chief Todd Chamberlain said at a press conference in October that Dillard was reportedly trying to steal another man’s car keys by brandishing what turned out to be a “tactical replica” of an assault-style gun. It was also described as a “tactical air rifle.”

Dillard and the victim struggled for a while before the Dillard struck the victim in the head with a rock, witnesses told police.

He then walked down the street and pulled the air rifle from his nearby van while trying to intimidate community members with it, including threatening a woman on the street, Chamberlain said.

“That replica of a tactical air rifle looks exactly the same as an authentic AR-15,” Chamberlain said last month.

When police arrived, Dillard was told by police to drop the weapon. He pointed it at the officers, and one officer fired two rounds, officer body cam video shows.

The gunfire struck Dillard and he was rushed to a nearby hospital, where he died from his injuries, police said.

“I don’t know why he felt the need to continue on and escalate that once the officers arrived,” Chamberlain said, “but what I do know is that those officers responded to a very, very fluid, a very, very dangerous situation, and they took the action that at that time, and their perception in their mind was the only due course that they could take.”

The investigation is ongoing, and Chamberlain said in October police are searching for questions about the suspect’s actions. He plans to contact family and friends to pinpoint the cause.

Dillard was reported by police to be visiting his girlfriend at apartments where the shooting took place shortly before the incident happened.

“We think that in this apartment complex is a possible girlfriend of our suspect, and from what we know from initial conversations with her is that she was intimidated, she was afraid of his actions and his behavior, and she didn’t let him into that apartment,” Chamberlain said.

Police did not release new details linking the Dillard to the apartment.

Investigators said it appears the man was living in the van outside Brent’s Place where he retrieved the air rifle.

Brent’s Place provides housing for families with children or adults receiving long-term health care at one of several healthcare institutions nearby at the Anschutz Medical Campus.

Speaking to questions about whether a mental-health crisis unit should have handled the 911 call, Chamberlain said that with the appearance of an assault rifle and the extent of the violence Dillard was showing at the time, police were the required approach.

Chamberlain said it was “alarming” that a fight involving someone armed with an “AR-style” weapon occurred where dozens of families stay for healthcare and nearby a middle school.

Parallel to an Aurora investigation into the shooting, a Critical Incidence Response Team is providing a separate investigation. Under state law, CIRT units, comprising the district attorney and other metro police departments, make determinations on whether shootings are justified, or whether criminal charges are warranted.
