GREAT MILLS, Md. (WMAR) - A gunman is dead and two other students are injured following a Maryland high school shooting Tuesday morning.
Deputies identified the shooter as 17-year-old Austin Wyatt Rollins, a student at Great Mills High School in St. Mary's County.
During a press conference, the St. Mary's County Sheriff's Office said that Rollins walked into Great Mills High School with a gun. Around 7:55 a.m., 16-year-old Jaelynn Willey, and a 14-year-old boy were shot in Hallway F.
Deputies say the School Resource Officer, Deputy Blaine Gaskill, was alerted, pursued Rollins, and fired a shot in his direction. Almost immediately the student shot back, but Deputy Gaskill was not hit. It is still under investigation whether the officer's shot was what killed the gunman.
The SRO, who Governor Hogan says was a former SWAT member, is being hailed a hero.
