Denver police put Green Valley Ranch on alert Tuesday, telling neighbors that Andrew Michael Tenorio, a court-designated sexually violent predator, is living at 5437 Danube Street in northeast Denver. The department said the alert is part of routine community notification required under state law and reminded residents to use official phone lines, not social media, if they have concerns.
What the department posted
In a recent social media alert, the Denver Police Department identified Tenorio by name, listed the Green Valley Ranch address, and linked to a short explainer video the department uses to walk residents through sexually violent predator notifications. The post also stressed that "this social media platform is not monitored 24/7" and gave out phone contacts for any follow-up.
According to the Denver Police Department, residents with registration questions should contact the Sex Offender Registration/Compliance Unit at 720-913-6511.
Why the notice is required
Under Colorado law, police must notify the community when someone has been adjudicated a sexually violent predator. The state sex-offender site notes that SVPs are considered "the highest risk sex offenders" and are listed when they are living in the community, not just passing through.
The Colorado registry is updated hourly, and local law enforcement agencies are the ones tasked with actually getting the word out so neighbors know both the basic risk information and where to report concerns. Per the Colorado Bureau of Investigation, the listings are meant to raise awareness and are not a stand-in for calling 911 if there is an emergency.
Where to verify records and who handles registrations
Denver's Sex Offender Registration Unit oversees address verification for registrants, handles updates, and operates out of the Police Administration Building at 1331 Cherokee Street, according to the department's operations manual. That unit conducts house checks, coordinates with state systems to report any address changes, and serves as the main contact point for administrative questions about a registrant's status.
The manual also spells out procedures for follow-up checks and clarifies that in-person registration happens at the Cherokee Street office, as outlined in the Denver Police Department document.
How residents should respond
Police say neighbors should treat this as an awareness notice, not a cue to handle anything themselves. Residents are advised to call 911 if they believe a crime is in progress. For non-urgent questions or tips, Denver's non-emergency line is 720-913-2000, and the Sex Offender Registration/Compliance Unit can be reached at 720-913-6511.
The department also reminded people not to try to request police services through social media and to stick to official phone lines instead. As posted on Nextdoor, the department links to a short video that breaks down the SVP designation and how residents can report concerns.
Neighborhood context
Denver has pushed out a series of similar neighborhood alerts in recent months as court-designated sexually violent predators relocate to different parts of the city, a pattern local outlets have been tracking while consistently urging residents to rely on verified, official information. Recent coverage highlights the way the department uses short videos and targeted neighborhood notices to boost awareness of the registry and steer people toward the correct contacts for questions or tips.
