US-SHOOTING-SCHOOL

Dr. Igor Nichiporenko (L), Medical Director of Trauma Surgeons, and Dr. Evan Boyar (R), Medical Director of Emergency Surgeons, both of the Broward Health Emergency facility where victims of a shooting at Marjory Stoneman Douglas High School were treated, speak to the media in Parkland, Florida on Febreuary 14, 2018. A former student armed with an AR-15 rifle opened fire at a Florida high school, killing at least 17 people, officials said, in a harrowing shooting spree that saw terrified students hiding in closets and under desks as they texted for help. Broward County Sheriff Scott Israel identified the gunman as Nikolas Cruz, 19, a former student at Marjory Stoneman Douglas High School in Parkland who had been expelled for "disciplinary reasons."
