"many details of what exactly happened last Oct. 1 have not been disclosed, and the official county investigation report has not been concluded and released."
 
 It doesn't surprise me one bit. There are so many unanswered questions - 

 How did the Shooter get to the school with a bag of guns if his car was found in his apartment's parking space after the shooting?
 
How did the shooter get the bag of guns Into the School?
 
Where was the bag while he sat in the classroom?

Why was he Not identified as an African American? 

...and much more.
