Two injured in US school shooting, shooter killed

Great Mills, March 20 

A student who shot and critically wounded two fellow students at a Maryland high school on Tuesday morning, has died after exchanging gunfire with a campus security officer, the county sheriff said.

The school day had barely begun when the student, who has not been identified, shot a male student and a girl student at Great Mills High School in St. Mary’s County before the campus security officer intervened, county Sheriff Timothy Cameron told NBC’s Washington affiliate.

The two victims were in critical condition at hospitals.

The officer was not harmed, and the public school’s roughly 1,600 students were later escorted off campus by police, classroom by classroom, to reunite with their parents.

It is “more than possible” that the explosion is linked to the prior ones in taking place in Austin, as the package was believed to be headed toward that city, which has witnessed  four bombings this month. — Agencies
