Two bystanders were hit by shotgun pellets and taken to a hospital. A retired deputy sheriff suffered a slight hand injury.
Meanwhile, authorities in Ohio said a gun dealer in Medina was checking out a semi-automatic handgun he had bought when he accidentally pulled the trigger, injuring his friend. The gun's magazine had been removed from the firearm but one round remained in the chamber, police said.
Police Chief Pat Berarducci said it appears the bullet struck the floor and the man was wounded in the arm and leg. Berarducci said the man was taken by helicopter to a Cleveland hospital. His condition was not immediately known.
