The woman shot Tuesday at her office in downtown Denver has died, Denver police said Wednesday morning.

Cara Russell, who was identified Wednesday afternoon by the medical examiner’s office, had filed for divorce in April from Mickey Russell, who police said shot Cara several times at her office near 15th and Wynkoop streets, Denver police Cmdr. Ron Saunier said at a news conference Wednesday.

Cara Russell was 52 years old, according to the Denver Medical Examiner’s Office. She was an executive director for the Colorado Association for Recycling on the second floor of The Alliance Center at 1536 Wynkoop St. The building is known in political circles as a hub for environmental and social-justice organizations.

Mickey Russell, 58, died from a self-inflicted gunshot wound, the medical examiner’s office said.

Mickey Russell, from Buena Vista, had been increasingly unstable, said Saunier, who oversees the major crimes division for the police department. He had been banned from the airport, and police were investigating whether a mental health hold had been placed on him in another mountain town, Saunier said. He had no criminal history.

“He came there with the intent of getting the victim,” Saunier said. “We’re hearing there had been some rumblings and talks of him doing this.”

Mickey Russell first tried to enter the building through a doorway in an alley, but it was locked to non-employees, Saunier said. He then went in the front door with a handgun and there was a short chase inside the office. Police said there were about 120 witnesses, and some tried to intervene.

The office layout made it hard to hide from the shooter, Saunier said.

The initial police dispatch, at 2:42 p.m. Tuesday, said there was “an active shooter in the stairwell.” And, soon, the police radio filled with reports coming from people calling 911 while hiding underneath their desks or barricaded inside their office suites.

The city’s SWAT team entered the building within five minutes of receiving the call, according to police dispatch recordings archived on the website Broadcastify. But, by then, many workers had already fled.

The incident disrupted the afternoon work day as dozens of offices went on lockdown in LoDo. Streets were closed to traffic as police cleared the building.

The police department’s SWAT team responded quickly and the police department’s plan for responding to active shooter calls went well, Saunier said.

“In this day and age, when you receive a call of an active shooter you don’t know what you may have,” he said.

Saunier also offered condolences to the families of those who died and to the co-workers who knew the victim and witnessed the shooting. The police department will offer its victims’ services to them, he said.
