Johnston county deputies arrested an 11-year-old student and his mother, who faces charges for not properly storing the gun.
Some parents more upset about how the school alerted them to the potential danger. Parents were told by phone and letter that something inappropriate was brought to school but not that it was a gun, or a weapon.
"Parents have a right to know," said father Tony Williams. "I pay for people to go in there. I deserve the right to know what goes on."
The point of the letter was to reassure parents that administration was aware and acted promptly and students were safe," said Tracey Peedin-Jones, with Johnston County Schools.
Investigators aren't releasing the student's name because of his age.
