DENVER — Denver Assistant Deputy District Attorney Ryan Brackley announced his resignation Monday after a recent personnel investigation.

Denver District Attorney Beth McCann said in a statement that she and Brackley agreed that it was in the best interest of the office that he resign.

The personnel investigation was connected to reports of bullying in the office.

A redacted copy of the final report by the Employers Council accuses Brankley of swinging a wooden baseball bat in the direction of a fellow prosecutor while also accusing Brankley of calling a co-worker a “(expletive) fat (expletive).”

In trying to restructure Brackley’s job responsibilities, McCann said it became clear that a separation was the best solution.

Brackley’s last day is Friday.

“This decision was very difficult,” McCann said in a statement. “Ryan brought great value to the office in many ways, and he accomplished important and significant work for us and the city of Denver.

“I admire his passion, hard work, commitment to the office and considerable trial skills. I thank Ryan for his heartfelt and outstanding contributions to me, my administration, this office and to the city as a whole.”

“It is with regret that I have decided to leave the Denver DA’s Office,” Brackley said in a statement. “Although we accomplished a great deal over the past two years, there is more work to be done in order to achieve the goals laid out by District Attorney McCann.

“I appreciate her speaking so highly of my work ethic, energy, and the positive impact i had on the office in serving as her second-in-command.

“In order for the office to achieve DA McCann’s goals of enhancing public safety and achieving meaningful criminal justice reform, I think it is best for me to move on.”

Helen Morgan, the chief deputy of the Behavioral Health Unit, will assume Brackley’s responsibilities on an interim basis beginning this week.
