A shooting has occurred at Great Mills High School in Great Mills, Maryland. Multiple injuries have been reported and several people have been taken to a local hospital. The Sheriff's Department is telling parents to steer clear of the school and drive another 15 minutes to Leonardtown High School instead for more information and to be reunited with their children.

A single shooter fired at a female victim, according to St. Mary's County Sheriff Tim Cameron. He was quickly engaged by the school resource officer. The female victim is in critical condition, as is the shooter. Another victim was hit by gunfire and is in stable condition.

Cpl. Julie Yingling of the St. Mary's County Sheriff's Office told NBC Washington that the scene is "contained" and "no longer active." The school is still on lockdown, however, as police conduct an investigation. The Bureau of Alcohol, Tobacco, Firearms and Explosives has also responded.

Both Maryland Gov. Larry Hogan and Rep. Steny Hoyer (D-MD) said they are keeping their eyes on the situation.

This shooting occurs just a few days before the March for Our Lives event in Washington, D.C., organized after the mass shooting at Marjory Stoneman Douglas High School in Parkland, Florida. One of the Parkland student survivors, Emma Gonzalez, tweeted that she and her classmates were thinking of the Great Mills community.
