From an article:
The 12-year-old boy was shooting the .22 caliber gun outside of his Penrose home on County Road 123, according to a Fremont County Sheriff’s news release. After shooting the gun, the boy walked back home, dropped the gun and it discharged. He was hit by a single bullet in the abdomen.
His stepfather was home and took him to St. Thomas More Hospital, where he had surgery on the non-life threatening wound.
Every gun in the hands of a child must first pass through the hands of an adult.
