A teenager will serve 80 days of incarceration for driving nearly 100 miles per hour in a swerving thrill ride that pitched two of his four teen passengers to their deaths along an interstate frontage road in Burnsville.

Joshua L. Decoteau, 18, of Burnsville, was sentenced Monday in Dakota County Juvenile Court after pleading guilty earlier this month to two felony counts of criminal vehicular homicide involving gross negligence, one felony count of criminal vehicular operation resulting in substantial bodily harm and one gross-misdemeanor count of criminal vehicular operation.

Decoteau was 17 at the time of the Aug. 21, 2012, crash that killed Frederick J. Alexander, 16, of Burnsville, and Alesha K. Roehl, 17, of rural Northfield. The case was prosecuted under the state's extended juvenile jurisdiction statute, which gives the juvenile court jurisdiction over Decoteau until he turns 21.

Judge Tim Wermager ordered Decoteau to serve 60 days in the Juvenile Service Center as well as another 10 days in jail on the anniversary of the deaths in 2014 and 2015. He also must perform 100 hours of community service.

If he does not comply, Decoteau could receive the full adult sentence, which for criminal vehicular homicide is typically four years.

Passengers Jonathan L. Thomas, of Lakeville, and Rey Chacon, of Burnsville, survived their injuries. Decoteau was slightly hurt. Decoteau and Thomas wore seat belts. Chacon, Alexander and Roehl did not.
