A driver who was high on marijuana when he caused a head-on collision that killed a woman and her daughter and injured two others has been sentenced to serve two decades in prison.
Franklin County prosecutors say a blood test found Aaron Fields had quadruple the amount of marijuana legally allowed to be in his system during the January 2015 Columbus crash. Thirty-two-year-old Tanya Knipp and her 16-year-old daughter Tessa Knipp died from injuries sustained in the crash. Fields had been on parole at the time after being imprisoned for burglary. Fields pleaded guilty last month to charges including aggravated vehicular homicide and aggravated vehicular assault.
