HS student shooters. 

Up until a certain point in recent decades, this did not happen. Nobody does that. Not what they did, the way they did it.  

 I don't have a reference on hand but I found something when researching an Rx drug or related topic.. You might know the connection between these kids was briefly reported / broadcast: anti depressant drug treatment before suddenly - you couldn't find reference to it. Not easily anyway. 

Showed up at school looking same as yesterday but  mentally turned inside out. 

 I guess with enough power, money and motive, you can silence anyone, change anything.
