Cheezo Check-in: Parent App Alert

Have you heard of the NGL app? (Not Gonna Lie)

NGL allows users to receive anonymous questions and messages through their social media accounts. While it may seem like harmless fun, anonymity can create serious concerns for parents and caregivers.

Potential risks include:
• Cyberbullying and harassment
• Inappropriate anonymous messages
• Negative effects on self-esteem and mental health
• Difficulty identifying who sent a message
• Pressure to share personal information

Safety tips for parents:
• Talk with your child about anonymous messaging apps
• Discuss what to do if they receive a hurtful or concerning message
• Review privacy settings together
• Encourage them to tell a trusted adult about online bullying
• Remind them that not everyone online has good intentions

Is NGL safe for children?
As with many social media apps, safety depends on a child’s age, maturity, and how the app is used. Because NGL centers on anonymous messaging, parents should use caution and closely supervise its use.

The best protection is an ongoing conversation with your child about online safety, responsible digital citizenship, and knowing when to ask for help.

Celebrating Dennis Huner’s Dedicated Service and Retirement

After nearly 39 years of dedicated service, Dennis Huner has retired from the Jefferson County Sheriff’s Office.

Since beginning his career on February 22, 1988, Dennis has served with professionalism and distinction in nearly every division of our agency. His extraordinary career included lifesaving actions, leadership in the Fugitive Unit, the creation of JCSO’s Bicycle Patrol Program and more than 100 composite drawings completed for law enforcement agencies across the region. Most recently, his exceptional work in the Evidence Vault Unit earned him the 2024 Investigations Professional Employee of the Year award.

Sheriff Reggie Marinelli and Undersheriff Mike Prange thanked Dennis for his decades of service, perseverance and outstanding work ethic.

Dennis, you have made a lasting impact on JCSO and the community we serve. Congratulations on your well-earned retirement. We wish you all the best in this next chapter!

Meet Our Newest K9s: Vision and Reba! 🐾

We are proud to introduce K9 Vision and K9 Reba, who officially earned their narcotics detection certifications from the Colorado Police Canine Association on August 12, 2026.

K9 Vision is partnered with Deputy Flusser, and K9 Reba is partnered with Deputy Diehl. Both teams are assigned to the Detentions Facility and are trained to detect dangerous narcotics, including co***ne, methamphetamine, he**in and fentanyl, in buildings and vehicles.

The presence of illegal drugs is a serious challenge faced by detention facilities across the country, including ours. Despite ongoing screening and prevention efforts, drugs can still be smuggled inside, putting lives at risk. Vision and Reba will provide an important additional layer of protection by helping deputies locate hidden contraband before it can cause harm. Their work will strengthen our efforts to protect everyone who lives and works inside the facility.

Please join us in welcoming the teams: Deputy Flusser and K9 Vision, along with Deputy Diehl and K9 Reba. We are grateful to have these dedicated teams serving and protecting our jail and community!

Today, we welcomed U.S. Senator John Hickenlooper to our newly renovated Emergency Operations Center for a roundtable led by Sheriff Reggie Marinelli with fire service partners from across Jeffco!

We shared how our new Wildland Fire Management Program is strengthening year-round wildfire response, reducing risk through strategic mitigation projects, and helping residents prepare through education, home assessments, and financial assistance.

We also discussed the work ahead - and the need for continued federal support, sustainable funding, and consistent policies and building codes.

We appreciate Senator Hickenlooper taking the time to visit, listen closely to our partners, and demonstrate a thoughtful understanding of our community, its landscape, and its unique needs. Thanks also to the fire agencies who participated in today's event.

Protecting Jefferson County from wildfire takes all of us working together to prepare, respond and recover.
Senator John Hickenlooper

Fire Restrictions Update

Effective today, August 18, 2026, Jefferson County Sheriff Reggie Marinelli has rescinded the temporary Stage 2 Fire Ban and reinstated Stage 1 Fire Restrictions for all unincorporated areas of Jefferson County.

Despite recent monsoonal moisture we still have persistent drought conditions, along with dry vegetation and soils, which continue to create a risk of wildfire growth. Elevated national preparedness levels may also limit resources available for new wildfire incidents.

Please remember:
• Denver Mountain Parks and Jefferson County Parks and Open Space remain under a year-round Stage 2 Fire Ban.
• Restrictions on nearby municipal, county and federal lands may differ or change in the coming days and weeks.

For complete Stage 1 Fire Restriction details, visit the link in the first comment.
