@abc7chicago: Wisconsin 2nd Grader recalls her experience from Monday's deadly shooting. "I was in the hallway, and I was changing from my shoes to my boots to go to lunch, because I have recess after, but then I heard the shooting and screams." - Details are still emerging about the course of the Madison, Wisconsin, school shooting that left three people -- among them the 15-year-old female shooter -- dead and several others injured on Monday. Police said that Natalie Rupnow, who went by Samantha, used a handgun to kill one teacher and one fellow student in the shooting.
