Don't expect the Enemedia to note this information gap.
Also, there needs to be a simple test developed to identify people with a serious lack of impulse control... besides stabbing someone to death for no reason at all, or all of the road rage videos seen on YouTube.
Heard some gossip around water cooler from parents with kids from those schools. Take all this with large grain of salt but this is a synopsis:
Stabber was constant discipline problem (fighting) at his own school. Both stabber and stabbed were football players at schools with nasty rivalry. At track meet stabber posted up next to rival school’s shade tent (not near his own teammates). Stabbed took exception to this and told stabber to scram. This led to verbal altercation which escalated into a physical altercation. Hearing that stabbed was beating stabber pretty badly when knife was pulled out and used.
