Apparently, in this one county in Ohio, its a yearly prank for young Amish people to get dressed up and throw tomatoes at passing cars. Except this time, somebody got out of their car and shot one of them to death. It sounds pretty loco:

According to the sheriff’s department, the driver of a Lincoln or Cadillac stopped, got out and threatened to shoot whoever threw the tomatoes Monday night.

The vehicle turned around and drove past the cornfield again. The car was struck with tomatoes a second time.

About 25 minutes later the vehicle passed the cornfield two more times. On a third pass, the driver stopped and challenged the group to throw more tomatoes — then fired his shotgun into the cornfield.
