* Nov 21st a teacher sees the kid searching ammunition during class, tells administration who in turn contacts the parents, leading to voice-mail. They also send an email which again gets no response. * That same day, the mom text the son,"LOL. I'm not mad at you. You have to learn not to get caught." * Nov 26th, the father, in the presence of his son, purchases a gun. There is an instagram post floating around of Ethan bragging about "my new beauty" [photo of the gun], I can't find the exact date being reported on, but the screencap says "4 days ago" which if taken from the day of the shooting would be this same day the gun is purchased. * Nov 30th (day of the shooting) a teacher notices a drawing on the kid's desk of a gun, a bullet, a bleeding victim, and ominous text. Parents are immediately called to the school to discuss along with the kid pulled from class. * Parents resist the idea of taking their child out of class for the day, not yet realizing he at this point has their gun with him. They're told he's required counselling in the next 48 hours, parents go home, kid returns to class. * After news gets out later that day that a shooting is taking place at the high school, at 1:22pm the mom texts her son "Ethan, don't do it." * 1:37pm the father contacts authorities about the gun missing from the house, alerting them that their son may be the shooter. The gun was stored in an unlocked drawer in the parents bedroom.
