Officials in Georgia have decided not to file charges in the death of a 3-year-old boy who pulled a gun from his father’s backpack and fatally shot himself in the chest in April.

The boy, Holston Cole, was one of four young children who died from accidental, self-inflicted gunshot wounds during a one-week span in April. According to a statement released by the Paulding County Sheriff’s Office on Thursday, sheriff’s detectives and the county district attorney’s office decided not to move forward with charges, saying the evidence suggested that the shooting was not intentional.

“Detectives confirmed that this was an accidental shooting and that charges will not be pursued,” the statement said.

The deaths of the four children in one week encapsulated how cases like these can be handled differently from state to state, and depending on the details of each case:

• After Sha’Quille Kornegay, a 2-year-old in Kansas City, Mo., shot and killed herself with a gun her father often kept under his pillow, the authorities charged her father, Courtenay Block, with second-degree murder and child endangerment.
