Lincoln County residents and the law enforcement community are mourning the death of Undersheriff John Hyslop.

In the early morning hours of Jan. 8, Hyslop, 57, died at his home in Libby. 

Across social media platforms, those who knew or knew of Hyslop, offered their condolences, prayers and words of support to his family.

Hyslop began his law enforcement career on May 22, 2013, when he was accepted as a reserve deputy sheriff with the Lincoln County Sheriff’s Office under Sheriff Roby Bowe. In September 2013, he was appointed as a full time deputy sheriff. 

Throughout his career, Hyslop served the Lincoln County Sheriff’s Office in many capacities. He was frequently relied upon for his technical expertise, providing critical support with information technology and electronic equipment. 

His official assignments included evidence technician and field training officer, where he mentored and trained new deputies. He served with distinction and dedication in his role as undersheriff following his appointment in November 2024 by Sheriff Darren Short. 

While Hyslop excelled in every role he undertook, his greatest professional passion was serving as a K9 handler alongside his narcotics K9 partner, Bear. Together, Hyslop and Bear became widely recognized throughout Northwest Montana for their exceptional proficiency in the detection of illegal narcotics. 

Hyslop was also active in working with the area's youth. He participated in many assemblies at area schools, educating children about drugs and he was also involved with the county's Shop with a Cop program that ensured children would have Christmas presents.

The Lincoln County Sheriff’s Office asked that community members keep Hyslop’s wife, Karen, his mother, Judy, and his family, friends, and law enforcement colleagues in their thoughts and prayers. 

The official obituary and funeral service dates and additional details will be announced when information is available.
