KALISPELL — A Whitefish man has reached a plea agreement in the July 2018 stabbing death of his father.
Attorney Will Managhan filed court records saying 27-year-old Tanner Hosek planned to plead guilty to mitigated deliberate homicide by reason of mental disorder. An autopsy found 65-year-old Eric Hosek had been stabbed 10 times.
Tanner Hosek's change-of-plea hearing is set for Nov. 7. He is expected to appear via video from the Montana State Hospital, where he has been committed since last year.
