.Jim Gard's math class at Marjory Stoneman Douglas High School in Parkland, Florida, was just finishing up a review for a test Wednesday when"the fire alarm went off. He said "I thought it was unusual because we'd just had a fire drill." It wasn't another fire drill, or even a fire. It was far, far worse. Authorities said Nikolas Cruz, a 19-year-old man who'd recently been expelled from the school, had returned to campus and opened fire with an AR-15 semiautomatic rifle.
