As many as 10 people were injured when a St. Charles man accidentally fired his gun at an Elburn-area gun club, police said.

About 7:30 p.m. Tuesday, the man had just completed shooting at the St. Charles Sportsman’s Club, 44W471 Keslinger Road, just outside Elburn, where he is a member, said Kane County Sheriff’s police.

In the clubhouse, the man was about to put away his 12-gauge shotgun, police said. Thinking he had placed a snap cap – a device that preserves the firing pin during storage – into the gun the man actually loaded a live round, police said.

He then pulled the trigger while the shotgun was aimed at the floor, discharging the gun. The fired ammunition ricocheted up and hit 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 Hospital in Geneva with non-life-threatening injuries, according to police. About seven others, including the shooter, were treated at the scene, police said.

Because the incident was an accident, police said there will be no criminal charges.
