The teenage driver in a single-vehicle wreck that killed a rising North Forsyth High School senior last June faces five years in prison after pleading guilty to first-degree vehicular homicide. According to Forsyth County Superior Court records, 18-year-old Adam Robert Joseph DiMillo was sentenced to 15 years and will serve the first five in confinement, with the remainder spent on probation, pending good behavior. Superior Court Judge David Dickinson allowed DiMillo to complete a residential substance abuse treatment program before reporting to the Forsyth County Detention Center on July 20, when he will then be transported into the state penal system, according to court records.
