The embattled Denver Sheriff Department has 114 open internal affairs investigations, with nearly a third of those involving allegations of excessive force by deputies, city records show.

Denver Sheriff Gary Wilson said Thursday that he is addressing the issue of deputy misconduct by introducing new training and other resources to help deputies deal with stress. The plan includes mentoring for recruits, a new chaplaincy program and an evaluation of shift and work hours.

“These officers work in an environment where they’re charged to maintain order. They’re charged to maintain discipline,” Wilson said. “And that’s with people who aren’t always compliant and the ever-present potential for violence.

“You couple that with real-life stressors that are off the job. When that stress goes unmanaged too long, it can lead to bad decisions.”

Officer stress also has been a problem at the Denver Police Department.

Chief Robert White ordered a review of the department’s handling of alcohol abuse within the ranks. The chief said he was concerned after a rash of officer arrests, most of which were alcohol-related.

Of the 114 sheriff’s cases under investigation, 70 have been filed this year. Forty-two were filed last year, and two are holdovers from 2012, said Mary Dulacki, records coordinator for the Denver Department of Safety.

Thirty-five cases involve allegations of excessive force, Dulacki said.
