MINNEAPOLIS (AP) – A Minnesota man accused of shooting at a school bus on a snowy highway, wounding the driver, has pleaded guilty to first-degree assault. Thirty-two-year-old Kenneth Lilly of St. Paul waived his self-defense claims Monday. The bus driver was trying to merge onto an interstate near downtown Minneapolis during a snowstorm in February when the bus scraped Lilly’s car. Lilly fired five shots into the bus windshield, wounding the driver’s arm. A girl on the bus was not hurt.
