Chief Brian Kozak

Kozak was appointed to lead the Cheyenne Police Department in 2010 and is the longest-serving chief in the history of the CPD.

Collins wrote that ''Chief Kozak was able to modify the numbers in one day. I can’t understand why he chose to not fix them over the past five years.''

Outgoing Mayor Marian Orr said, "It’s abundantly clear Mr Collins didn’t bother to fact-check the data he cited."

Cheyenne Police Chief Brian Kozak says Mayor-elect Patrick Collins' decision not to retain him due to crime numbers was based on inaccurate data.

The Cheyenne Police Department is looking to add six more officers to its ranks.

Cheyenne Police Chief Brian Kozak says this year has been the "hardest and most stressful" of his 35-year policing career.

Police Chief Brian Kozak on Tuesday took a moment to reflect on Police Week and remember those Cheyenne officers who paid the ultimate sacrifice.
