 No students were hurt, police said. Officers confronted the teen outside the school and the gunman then "reportedly shot out the glass of a locked entry door" and ran inside the building, police said. Police trapped him there and that’s when he shot himself, officials said. "If that person hadn't made that call we'd be having a much different conversation right now," an Indiana State Police Supt. "It is important to emphasize that due to the result of advance notification of the potential for a violent act at the school, the school was able to initiate their lockdown procedure yesterday and police were able to have a rapid response, which undoubtedly prevented injury to students and faculty.

– An Indiana mom made a heart-wrenching choice, and now her community is rallying around her. Dozens showed up for a candlelight vigil Sunday in Richmond to support Mary York, who called 911 Thursday to warn that her son was going to Dennis Intermediate School with a gun, per ABC News and WTHR. Police confronted 14-year-old Brandon Clegg at the school and engaged him in a shootout before he took his own life. Clegg's family says he had been bullied at school, which they say is no justification—just an explanation of what happened. "It destroys me to think that a kid would have to go and show his anger at a school and that he would go as far as shooting at people..." says his cousin, Thomas York. "It sucks." But most of the attention is going to Brandon's mom, 42, who made a difficult phone call that almost certainly saved lives. "She's a human. She's a mother," says vigil organizer Shawn Wright. "She lost her child." As an Indiana state police superintendent tells WCPO: "If [York] hadn't made that call, we'd be having a much different conversation right now." (On the sixth anniversary of Sandy Hook, there was a nerve-wracking morning.)
