From the article:
According to a police report, a 12-year-old boy was watching television in the living room about 9:30 p.m. Feb. 9 at 5506 LaChapelle Bend when he saw his 15-year-old brother enter and raise a gun. The boy heard a loud bang but didn't know he was shot until his brother started screaming, the report said.
The 15-year-old called his father, 47-year-old Carey Wade Jones. The father rushed his son to Trident Hospital as he called 911. Police said the bullet went through the 12-year-old's cheek and chin, then lodged in his chest.
Officers later recovered a black revolver.
"Investigators were able to determine that the incident was an accidental shooting and no charge has been brought against the 15-year-old," police spokesman Spencer Pryor said. "The 15-year-old told investigators that he thought the gun was empty when he pointed it at his brother and pulled the trigger."(a related article)
