Five teenagers were target practicing with .22-caliber rifles near a subdivision in O'Fallon, Missouri. One of the bullets missed the target and traveled nearly three quarters of a mile before hitting a 16-year-old lifeguard at a crowded public pool.
Police seized four rifles but no charges have been filed because it's legal to shoot off guns in unincorporated St. Charles County.
"They need to find a better way to set up this target practice. If that bullet can come this far into the limits here, then they need to find a safer way to set that up," said a woman who was at the pool with her granddaughter.
