ELBURN, Ill. (STMW) — Two men and a 14-year-old boy were hospitalized and several other people injured when a shotgun accidentally fired and the round struck the floor, bounced up and struck them at a west suburban gun club Tuesday night.

Emergency personnel were called to the St. Charles Sportsmen’s Club at 44W471 Keslinger Rd. in unincorporated Blackberry Township near Elburn about 7:30 p.m., according to the Kane County Sheriff’s office.

A 69-year-old St. Charles man who belongs to the members-only club had just completed target shooting and entered the clubhouse. He was to putting his 12-gauge shotgun away and thought he had inserted a snap cap, a plug used to save the firing pin while a gun is stored, according to a statement from the sheriff’s office.

But instead of the snap cap, he put a live shotgun shell into the gun, police said. With the man pointed at the floor, he pulled the trigger, and the gun discharged, sending buckshot to the floor, where it bounced up and out and struck several people in the clubhouse, police said.

Three people—a 31-year-old West Chicago man, a 60-year-old Somonauk man, and a 14-year-old Geneva boy—- were taken to Delnor Community Hospital with non-life-threatening injuries, according to police.

Several others—police said at least seven but did not have a final list as of Wednesday morning—were treated at the scene, including the man who discharged the gun.

The sheriff’s office said the incident appears to be accidental in nature and it is unlikely that charges will be filed.

The club’s website boasts that it is “Dedicated to Sportsmanship Conservation Safety (and) Community.” The club, founded in 1933, “strive(s) to be good neighbors and community members, and do our best to promote the shooting sports in a safe, friendly environment.”
