How about simply never mentioning their name? Assign a number to them..... if folks really want to know their name, they can go to some publically accessible website to get it so it will in fact be available. However, never give notoriety to the killer by having his/her name repeated anywhere else.
Another thing....I truly don’t give a hoot ‘why’ they chose to kill students. In every case they planned and executed their plan to snuff them out.......that’s ‘cold blooded’ murder period.
