A tragic school shooting occurred at a K-2 school in Madison, Wisconsin, where a 15-year-old student, identified as Natalie Samantha Rupnow, opened fire, killing a teacher and a fellow student, and injuring six others before taking her own life. The incident adds to the alarming number of mass shootings in the U.S., which has reached 488 this year. The community is in shock, as parents waited hours to reunite with their children. Investigators are examining the shooter's social media for signs of extremist influences and are working with her parents to understand how she obtained a handgun. The school lacked a resource officer and metal detectors but had cameras and trained staff to monitor potential threats.
