News Release: Eighteen suspects responsible for organized and violent criminal activity throughout the state were recently arrested as part of a two-phase, multi-jurisdictional operation led by the Regional Anti-Violence Enforcement Network.
The 13-month investigation targeted 20 members of a local criminal organization responsible for more than 20 criminal episodes affecting 13 jurisdictions, including the cities of Aurora, Bennett, Commerce City, Denver, Frederick, Firestone, Greeley and Parker, as well as Adams, Arapahoe, Denver, Douglas and Weld counties.
Investigators obtained 67 search warrants and seized 31 fi***rms during the investigation. Arrest warrants were obtained for 18 suspects, including 14 adults and four minors, on a total of 185 criminal charges, including 166 felonies and 19 misdemeanors. All 18 suspects are in custody and charged in Denver District Court.
“This investigation demonstrates what can be accomplished when law enforcement agencies work together to hold violent offenders accountable and disrupt criminal networks operating across our communities,” said Deputy Chief Mark Hildebrand, who oversees the Aurora Police Department’s Investigations Division, which includes the RAVEN Task Force. “Over 13 months, this regional effort resulted in 18 arrests, 166 felony charges and the seizure of 31 fi***rms, addressing serious crimes that affected 13 jurisdictions across the Denver metro area and northern Colorado.
“These results reflect the commitment of our partner agencies to protecting our communities and ensuring those responsible for violent crime are held accountable for their actions and widespread victimization.”
The investigation was led by two task force officers from the Aurora Police Department and the Arapahoe County Sheriff’s Office. The suspects were arrested during two multi-jurisdictional operations on Sept. 15 and Oct. 7. The first take down operation targeted 12 suspects and all were taken into custody. The second take down operation targeted the remaining six suspects, five of whom were arrested that day. The final suspect was taken into custody days later.
The suspects were arrested in Aurora, Bennett, Commerce City, Denver, Greeley and Wichita, Kan. RAVEN agencies and other law enforcement partners that contributed resources or assisted with the operations include SWAT Teams from the Aurora, Commerce City, Brighton, Denver, Englewood, Greeley and the Littleton police departments, SWAT Teams from the Arapahoe County and Douglas County sheriff’s offices, the Arapahoe County Sheriff’s Office Special Operations Response Team, the Denver District Attorney’s Office, Kansas Highway Patrol, ATF and the U.S. Marshals Service.
“RAVEN’s success demonstrates the strength of collaboration among law enforcement agencies and our shared commitment to keeping communities safe,” said Arapahoe County Sheriff Tyler S. Brown. “By combining investigative expertise, resources and coordinated efforts across jurisdictions, our partner agencies helped disrupt this alleged criminal network.
“This regional partnership sends a clear message that those charged with violent and organized criminal activity will be pursued across jurisdictional boundaries, while reinforcing our commitment to protecting residents and holding individuals accountable through the justice system.”
