Maryland School Shooting Leaves 2 Students Critically Injured, Shooter DeadQuote"When the shooting took place, our school resource officer, who was stationed inside the school, was alerted to the event and the shots being fired. He pursued the shooter and engaged the shooter, during which that engagement he fired a round at the shooter," Cameron said.
Cameron said the shooter fired a round simultaneously.
"In the days to come, through a detailed investigation, we will be able to determine if our SRO's round struck the shooter," Cameron said.

Looks like an armed guard ended it.
Also mention of the kid having some past romantic involvement with the girl. :-\
My hat's off to Gaskill, the school resource officer, who put an end to the threat before the shooter could kill or injure any more students.
^Ditto.
Totally agree.
The girl that was shot was taken off life support and has died.
