(Minneapolis, MN)  --  The St. Paul man who shot a school bus driver on Interstate 35-W in Minneapolis could spend more than seven years in prison.  Thirty-two-year-old Kenneth Lilly received an 86-month sentence Friday for first-degree assault.  Lilly admitted to shooting five times at the bus last February during a snow storm.  One bullet grazed the head of driver Thomas and wounded his arm.  A young girl that was on the bus wasn't hurt.  Lilly was upset after the bus scraping his car while merging onto the interstate.  The complaint says got out of his car, walked over to the bus and fired at the windshield when the driver wouldn't open the door.
