Tanner Franks, 37 of Bozeman, was sentenced on Monday to 50 years in prison after pleading guilty in October to the 2017 stabbing death of his father, William "Bill" Franks.
In court Monday, District Court Judge Holly Brown sentenced Franks to 40 years on the mitigated deliberate homicide charge, with another ten years added for the use of a weapon. Judge Brown ordered that none of the time be suspended, though Franks will get credit for 756 days already served.
Franks changed his plea in October after initially denying that he killed his father in November 2017.
