No, but he was suspended after an incident on a school bus that led to a parent complaint.
My guess is that the other kid came home and told the parent "so-and-so drew a picture of him shooting me with a gun".............fast forward to the AP being involved!
I know it's not the norm, but it HAS happened:
Feb. 29, 2000
Mount Morris Township, Mich. Six-year-old Kayla Rolland shot dead at Buell Elementary School near Flint, Mich. The assailant was identified as a six-year-old boy with a .32-caliber handgun.
The above was obviously an extreme case, but still happened. Most school shooters are 14 or 15 or older.
