A 27-year-old Japanese bus driver was sentenced to up to 15 years in prison by a U.S. district court Friday following an accident that killed three Japanese tourists and injured 12 others in Utah last August.
Yasushi Mikuni will be held for one year, and after that, he will be put on three years' probation on the condition that he does not leave the state of Utah, according to a judge.
Mikuni was found to have caused the accident on Aug. 9, 2010, and lack of sleep was a probable cause. Mikuni had also smoked pot the previous day.
