A Suffern High School student will serve up to six months in prison and five years probation after pleading guilty to charges stemming from a fatal drunk driving crash earlier this year in Montebello that killed a Suffern High School freshman. News 12 says 17-year-old Joseph Debellis admitted he drove drunk and smoked pot the morning he crashed into a pole on Route 202. 16 year-old Jacqueline Zangrilli died at the scene. Debellis will be sentenced in March next year.
