Today we remember Jake Allmendinger who was killed in the line of duty on October 19,2019.

He was a husband, father, son, brother and co-worker who is missed everyday. His sacrifice for this community can never be forgotten.

Every first responder dedicates their career to the community they serve and they are acutely aware of the possible dangers that may lie ahead of them. Jake paid the ultimate sacrifice for Gallatin County and it is important this community continues to honor that sacrifice.

Until we see you again, rest easy Deputy Jake Allmendinger #677. God Bless.

Sheriff/Coroner Dan Springer releases the name of Blackmore Mountain fall fatality, and would like to express our deepest condolences to Mr. Callum Cook’s family and friends during this time.

In the late hours of Friday, October 2, 2026, Gallatin County 911 Dispatch received a call from a hiker on Blackmore Mountain reporting that his friend had fallen from the peak. Three teams of search and rescue volunteers were deployed to the area while Billings Med Flight and USAF 40th Helicopter Squadron in Malmstrom were engaged for support.

Search and Rescue volunteers staged at Hyalite Reservoir and climbed through the night, reaching the reporting party by 2:00am. They began efforts to locate the fall victim, identified as 20-year-old Callum Cook. The team completed rappel descents in the dark to locate Mr. Cook, who had fallen over 200' and was determined to be deceased on scene. Volunteers remained on the summit of Blackmore to support the reporting party, packing up the camp and safely hiking out. Due to the steep and technical terrain, the Search and Rescue Heli-Alpine Team then short-hauled to the scene via Central Helicopters and transported Mr. Cook to the coroner.

Sheriff Springer thanks the dedicated search and rescue team members for their work on this difficult overnight mission, along with the USAF 40th, Med Flight and Central Copters for their support.

It is with great sadness that we share the passing of retired Gallatin County Sheriff’s Office Captain Shane Frantz. Shane passed away on September 24, 2026, after a long-term illness.

Shane retired from the Sheriff’s Office in June 2022 after 32 years of dedicated service to the residents of Gallatin County. Throughout his career in law enforcement, Shane took on many important roles and accomplishments, including graduating from the FBI National Academy in 2005, serving as a detective, hiring and promotion officer, Special Response Team member, Search and Rescue coordinator, and lead fi****ms instructor.

But titles and accomplishments only tell a small part of Shane’s story. Shane was truly one of a kind, and his personality and sincerity made him a well-loved co-worker and respected leader. His impact on the Sheriff’s Office and the people he served will not be forgotten.

We are incredibly grateful to our friends at the Gallatin County Sheriff’s Foundation, who, in partnership with Shane’s family and friends, have established the Captain Shane Frantz Wellness Fund. The fund will provide support for our deputies as they navigate mental health and addiction challenges, helping carry forward Shane’s commitment to the well-being of those around him.

Our thoughts and condolences are with Shane’s family, friends, former colleagues, and all those who had the privilege of knowing him.

Thank you for 32 years of service, Captain Frantz. You will be deeply missed and never forgotten.

Captain Shane Frantz was laid to rest today after battling long-term illness. In conjunction with the Gallatin County Sheriff's Foundation, friends and Family have started the 'Captain Shane Frantz Wellness Fund'

Money attributed to this fund will help support our Deputies coping with mental health and addiction.

UPDATE: Suspects have been identified. Thank you for your help!

📢 Hey, Gallatin County, we need your help!

During the early morning hours of October 6 (approximately 2:00–4:00 a.m.), two individuals were seen walking through the Gallatin Heights Subdivision pulling on vehicle door handles. Vehicles that were left unlocked were entered and searched.

We are asking for the community’s assistance in identifying these individuals. If you recognize them or have security camera footage that may have captured them, please contact the Gallatin County Sheriff’s Office at 406-582-2100 (Option 1).

We also want to remind everyone to take a moment each night to lock your vehicle doors and remove any valuables. A quick nightly routine can help prevent crimes of opportunity.

Thank you for helping us keep our community safe!
