I know the crime is still being investigated or at least that's what's been reported but I have these questions:

How was the boy student able to get the slain teacher's body from a school restroom into nearby woods without being noticed by anyone?If he was noticed by anyone why wasn't this reported to authorities?  It has been reported that the accused boy did not become a suspect until he was later reported missing.

At what time did this henious crime occur.  If the transporting of the body wasn't noticed by anyone because it occurred at a time when the school was deserted or nearly deserted why were the teacher and the boy student still in the school?

Just wondering.
