KALISPELL, Mont. (AP) — 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.

Court records say Tanner Hosek has long struggled with mental health issues and has been diagnosed with bipolar disorder and schizophrenia. He was a ward of his parents as the time of his father’s death.

Linda Hosek told investigators her son had been in a psychotic state for two weeks prior to the stabbing.
