Police in Fairmont, MN, have charged five teenage boys in connection with the case of a trucker who was seriously injured when someone dropped a bowling ball off an overpass on Interstate 90.

The trucker – 54-year-old Theodore Maki of Missoula, MT – was hit by the ball after it smashed through his windshield on Aug. 27.

According to The Associated Press, 18-year-old Andrew Fellersen told police the group was only intending to hit the trailer, but that the 17-year-old with the ball dropped it too soon.
