A 16-year-old girl shot at a Maryland high school died late Thursday night after being taken off life support, officials said. In an emotional and extraordinary press conference Thursday, Melissa Willey said her daughter Jaelynn Willey had “no life left in her” after Tuesday’s shooting at Great Mills High School and would be removed from the machines that were keeping her alive. The shooter, 17-year-old Austin Rollins, is thought to have targeted Willey after a relationship with her recently ended. He was shot by a school resource officer and died at the scene, but officials did not say if he died by his own hand. “On Tuesday... our lives changed completely and totally forever. My daughter was hurt by a boy who shot her in the head and took everything from our lives,” Willey said.
