According to a news report:
The 11-year-old brought the .45-caliber semi-automatic handgun to show it to his friends.
While handling the gun, it went off and the bullet struck Arredondo in the shoulder.
He was taken to Salem Hospital to be treated.
Deputies said the gun was owned by the 11-year-old's father. He told deputies that the gun is normally stored in a gun safe at their home, and he was not aware his son had gained access to the weapon.
The district attorney's office will now determine if any charges should be filed against the 11-year-old boy or his father.
