Investigators on Monday identified a 14-year-old boy who died after his father shot him at a gun range that a local newspaper had described as "possibly being one of the safest indoor shooting ranges ever designed."

Initial reports indicated the son, Stephen Brumby, had shot himself on Sunday, but on Monday, the Sarasota County Sherriff's Office revealed that his father, William, fired the shot by accident.

It happened at High Noon Guns in Sarasota. A spent shell casing had hit a wall and fell into the back of the dad's shirt, investigators said. They added that the man accidentially pointed his gun behind him when it fired, and the round hit his son.

Paramedics rushed him to Sarasota Memorial Hospital where he died later that day.

Describing the safety measures in place at the gun range, the Sarasota Herald-Tribune reported that owner John Buchan had examined other ranges before helping to design his own. The walls reportedly included panels that reduce noise and absorb stray rounds, the newspaper reported in 2013. "It's as safe as we could make it," Buchan said.

The range reportedly doesn't allow children under 18 to fire guns there unless an adult is with them. However, kids under 14 -- accompanied by an adult -- can shoot for free.

The gun range did not immediately respond. The Bradenton Herald reported that a man who had a key to the business said, "All thoughts go to the family."
