Commerce City police present annual crime report; Flock gunshot detection shows 528 alerts, 36 stolen vehicles recovered
Summary
Police Chief presented the department’s yearlong crime data, detailed gunshot-detection totals and technology-driven improvements — including NIBIN links, drone-first-responder deployment and pursuit of CALEA accreditation.
Police Chief Guaylenola told the City Council that Commerce City police responded to a wide range of calls between July 1, 2024 and June 30, 2025 and outlined a set of new tools the department says are changing its approach to violent crime and vehicle theft.
The department’s gunshot-detection system — Flock — recorded 528 alerts in the area where sensors are deployed, Chief Guaylenola said. “The total alerts for the year in question that Flock let us know of gunfire was 528 in this area,” he said, adding that 123 alerts represented single gunshots and 405 were multiple-shot events. The chief said Flock-enabled responses helped officers recover 36 stolen vehicles “that would not have been recovered without that system alerting us to their presence. We made 33 arrests, and we recovered 11 firearms.”
Guaylenola outlined other technology and procedural developments: the department is expanding NIBIN (the National Integrated Ballistics Information Network) evidence collection aided by canine units trained to detect gunpowder residue; it rolled out PowerEngage citizen surveys tied to calls for service; and it began operating drones as a first-responder capability after receiving an FAA waiver to fly beyond visual line of sight.
The chief said a “real-time crime center” is planned to provide continuous monitoring of Flock and other camera systems and to coordinate drone responses; he said six civilian technician positions are budgeted for the center. Guaylenola said the department expects to achieve CALEA (Commission on Accreditation for Law Enforcement Agencies) national accreditation after a recent onsite assessment.
Council members pressed for specifics and context. Mayor Pro Tem Tim Noble asked why the public got only two public notifications connected to Suncor air exceedances earlier in the summer; Melody Mascarinas, the city sustainability manager, said the city and county were discussing the incident with state regulators. Council member Kim asked why CALEA accreditation matters; the chief said CALEA’s standards and external review “reassures our folks” and argued accreditation would place the department among the top agencies nationally.
Guaylenola also described how Flock alerts, NIBIN comparisons and drone deployments have already produced investigative leads and arrests: “We recovered 36 stolen vehicles… We made 33 arrests, and we recovered 11 firearms,” he said.
Ending: The chief invited council feedback on future reports and emphasized that some new tools — the Flock system, drones and NIBIN linkages — require continued investment and staffing to realize their full investigative benefit.
