Preston Rossbach will spend 60 years in the Montana State Prison for his involvement in a double homicide back in October of 2018.
In October 2018 Rossbach and Jonathan Whitworth entered a Missoula Hotel and shot Jason Flink, Megan McLaughlin and Kaleb Williams.
According to prosecutors, Rossbach also stabbed the three victims to leave no witnesses.
Flink and McLaughlin both died while Williams survived the incident.
Rossbach was found guilty by a Missoula jury in March on two counts of deliberate homicide, assault with a weapon, tampering with evidence and two counts of intimidation.
At sentencing on Friday Rossbach received 60 years for the two homicide counts, 10 years for assault with a weapon and 5 years for the other accounts, all will run concurrently.
