Updated to state that the shooter was a former student.
That was my first guess on opening this thread .. there be monsters
If they know the person is a former student, then they know the name of this perp. They have a duty to report the name, which they aren’t doing. It’s been long enough to notify the next of kin. I think they are waiting to scrub the social media from this perp.
