Libby, MT – The Lincoln County Sheriff’s Office is mourning the loss of Undersheriff John Hyslop, who passed away early January 8, 2026, at his home in Libby. He was 57.
According to a release from the Sheriff’s Office, Undersheriff Hyslop began his law enforcement career on May 22, 2013, when he joined the department as a Reserve Deputy Sheriff. He was promoted to full-time Deputy Sheriff that September and later appointed as Undersheriff in November 2024.
