A 4-year-old Alaska boy was shot in the leg when his mother's handgun fell out of its holster and fired. Alaska State Troopers say they took a call on the incident near Wasilla just before 11:30am on Saturday, and medics were treating the boy when they arrived. Troopers say the family was getting out of a pickup when the woman's .357-caliber handgun fell out of its holster, struck the pavement on its hammer, and fired. The shot hit the 4-year-old just above the knee. The bullet went through the boy's leg and lodged in a building. The boy was transported by helicopter to Anchorage for treatment. No one has been charged. (More Alaska stories.)
