A 14-year-old Phoenix, Arizona boy was having a sleepover at a friend's house with two other boys. While his friend was in the kitchen helping his mother with dinner, the two other boys went into one of the bedrooms and closed the door. The room had a gun rack on the wall and one of the boys took a shotgun down. Thinking it was not loaded, he racked the slide and pulled the trigger.
The gun fired, striking the other boy in the leg, hitting a major artery. The boy was rushed to the hospital where he is in critical condition.
Police continue to investigate the incident.
