A 60-year-old Minnesota man with 18 drunken-driving convictions will serve 20 months in prison for causing a crash that seriously injured two people in 2017.
Marshall A. Knoll pleaded guilty to first-degree driving while impaired in exchange for the dismissal of two more-serious charges. Prosecutors say Knoll was driving with a suspended license and was high on illicit drugs.
The Star Tribune reported Sunday that Knoll received a three-year prison sentence. With credit for time served, what remains of his sentence is 20 months.
Prosecutors say Knoll was speeding in his struck when he rear-ended another vehicle. One of that vehicle's occupants suffered a broken sternum, fractured ribs, a broken arm and bleeding in his brain. Another of the vehicle's passengers required spine surgery.
