Seven students have had "life-threatening injuries" and at least a total of 20 people were injured in a mass stabbing attack at a Pittsburgh area school. CNN reported on the morning of April 9, 2014, that the incident happened at Franklin Regional Senior High School, and it appears to have been done by a person that is a student at the school.
The suspect is currently in custody and no motive has yet been revealed for the attack.
The seven teenagers with "life-threatening" stab wounds are said to have been injured in the torso, chest, and back areas, according to a doctor. Four people have been flown from the location of the Pittsburgh school stabbing and out to hospitals by helicopter.
The injured students range in age from 14 to 17-years-old.
Dr. Chris Kaufmann of Forbes Regional Hospital in Monroeville, Pennsylvania, has said the injuries to seven teens are "quite serious" and "some are clearly life-threatening." An adult is also being treated for stab wounds.
Some of the other teens were said to have not such deep wounds and received minor lacerations.
Statements from the Franklin Regional School District's website said that all elementary schools were closed after the situation took place. The middle school and high school students were said to be secure.
Police are not said to be looking for another suspect in the matter.
