Former Parker police sergeant arrested after January incident, outside probe follows

A decorated Parker police sergeant whose career included nearly 10 years on the job and a 2025 Officer of the Year honor was arrested after a January allegation that pushed his case out of the department and into the hands of prosecutors.

Troy Brienzo, 31, was taken into custody April 3 after a grand jury indictment, according to local reporting. The charges reported in the case include two felony counts of unlawful sexual conduct by a peace officer, one misdemeanor count of unlawful sexual contact and four misdemeanor counts of official misconduct. The allegations involve two adult victims, and reporting said the incidents occurred during ride-alongs.

The Parker Police Department said it first learned of an alleged incident involving Brienzo on Jan. 7 and immediately placed him on administrative leave. The department also said it referred the matter to an outside law-enforcement agency to avoid even the appearance of a conflict, then fully cooperated with that independent probe. Brienzo resigned Feb. 13.

That sequence matters in Parker because it shows how the department handled a serious accusation involving one of its own: first remove the officer from duty, then send the case outside the chain of command, and let another agency develop the evidence. The case was later filed with the 23rd Judicial District Attorney’s Office, which prosecutes cases in Douglas, Elbert and Lincoln counties.

Brienzo’s fall carries added weight because of the image he had built in local law enforcement. Reporting described him as an Army veteran with multiple commendations and awards, and the Cherry Creek Valley Rotary Club of Parker recognized him as its 2025 Officer of the Year in May 2025. That public record now sits alongside a criminal case that will test not only Brienzo’s conduct but also the town’s confidence in how police misconduct is handled when the accused is an insider.

The broader question for Parker residents is whether the system that handled this case can sustain trust when allegations involve a longtime officer with deep ties inside the department. With the indictment now public and the case moving through the 23rd Judicial District, the focus shifts to the evidence, the prosecution and whether the department’s response was enough to preserve confidence in its standards.
