My school news paper sponsor taught journalism. I can remember that class very well. We had to write poetry, short stories and do this thing called brainstorming where we just wrote on paper whatever was going through our heads...even if our thoughts changed in the middle of it, we had to change what we were writing.
I was talking to my boyfriend about his journalism class and he had to do the same thing and I was surprised about the story he wrote. He had written a murder story that in the end turned out to be a dream (in the story).
THIS IS PURELY SPECULATION as all of our theories we come up with are nothing more than speculation.
Not that this teacher's death is anyway connected to Elizabeth's death, but it could be. It is possible that the suspect was in this guys class and did write a murder story. It is possible that the hand written evidence received by investigators was this story written by the suspect. (PURELY SPECULATION HERE)
If I were a teacher that already had some issues going on and then to have something like that thrown into the mix, I would be totally at a loss.
