MINNEAPOLIS — A Minnesota man who shot and wounded a school bus driver on a Minneapolis freeway during a snowstorm has been sentenced to more than seven years in prison.

Thirty-two-year-old Kenneth Lilly of St. Paul pleaded guilty in August to first-degree assault for the February attack that left Thomas Benson deaf in one ear and unable to continue working as a bus driver due to nerve damage in his hand. Lilly was sentenced Friday to 86 months.

Authorities said Benson was trying to merge onto the highway when his bus scraped Lilly’s car, although Lilly was unaware. During a traffic jam, Lilly walked in front of the bus and fired five shots into the windshield, wounding Benson’s arm and grazing his head. A girl on the bus was not hurt.

Defense attorneys asked for three years, citing Lilly’s “documented history of cognitive limitations.”
