Students and neighbors describe the suspect in the Florida high school shooting as a troubled teenager. They said he threatened and harassed other students. He talked about killing animals. And he shared photos of himself on social media posing with guns. On Wednesday, Nikolas Cruz killed 17 people and injured another 16. He used a semi-automatic rifle, an AR-15, at Marjory Stoneman Douglas High School in Parkland, Florida. Cruz had been expelled from the school for “disciplinary reasons,” the county sheriff said. Math teacher Jim Gard told the Miami Herald that before Wednesday’s fatal shooting, Cruz may have been identified as a potential threat. “There were problems with him last year threatening students, and I guess he was asked to leave campus,” Gard told the paper.
