The latest school shooting has left two students wounded and the gunman dead at Great Mills High School in Maryland's St. Mary's County, reports the Baltimore Sun. The shooting happened about 8am, and details are beginning to emerge: Sheriff Tim Cameron says a male student fired at a female student in a hallway, and he apparently struck her and a male student nearby, reports USA Today. A school resource officer arrived on the scene and fired at the shooter, says the sheriff, and "that stopped any further attack or assault."
The unidentified gunman is dead, says Cameron, but it was not immediately clear whether it was the shots fired by the school resource officer that killed him, per the AP. The Sun lists the 14-year-old boy as being in good condition; the 16-year-old girl was said to be hospitalized in critical condition but has been stabilized. FBI agents were on the scene to assist deputies. No word yet on a possible motive. (Read more school shooting stories.)
