MISSOULA, Mont. — A Montana man and woman have been sentenced to life in prison after pleading guilty to stabbing two people to death and trying to dissolve their bodies in chemical-filled tubs.
Tiffanie Pierce was sentenced to two concurrent life sentences with eligibility for parole.
Pierce reached a plea agreement with prosecutors in Missoula County District Court in early March on charges of attempted deliberate homicide and accountability to deliberate homicide.
Pierce's attempted deliberate homicide charge was related to a separate home invasion and stabbing that left one woman injured.
Augustus Standingrock, 26, who pleaded guilty in December, was sentenced to life with eligibility of parole.
Police found the bodies of 24-year-old Jackson Wiles and 15-year-old Marilyn Pickett dismembered and partially dissolved in the basement of Pierce's Missoula home in August 2017.
