HAMILTON — A Stevensville-area woman is facing vehicular homicide charges after a deadly ATV crash that killed her passenger last year.
Mackenzie Dawn Burt, 33, has been charged with vehicular homicide while under the influence in connection with a March 2025 crash at the intersection of Christianson Lane and Upper Burnt Fork School Road east of Stevensville.
Burt is accused of drinking alcohol before driving an ATV with 22-year-old Lillian Lois Tharp as a passenger.
Court documents state Burt was driving at a high rate of speed before hitting a vertical steel post head-on. Burt and Tharp were thrown more than 45 feet into a pasture, according to court documents.
Both were taken to a hospital in Missoula, where Tharp later died.
Burt's court date is scheduled for early April.
