As one may know already, the children of Sandy Hook elementary are returning to their school, the new school. The old school is now a crime scene and possible may be abandon. Who would use that school when a vicious crime was committed their?
When a crime or killing in a school happens, things may go paranormal scary. What I meant by this, children were killed in the school, and the gun man who killed them, left presence there.
It may eerie to investigate a crime scene where children were involved. What would happened if an investigator was looking for clues and he suddenly hears a child foot steps in the hall way or hear crying voices in the building. He is not alone in the building. It may not be scary, but there are spirits of children and a madman who died in the building.
What about the killer itself, he left an immense impression in the school. He killed many people and their spirits will remain there or be residual spirits trying to conduct a class and the killer will be their killing again.
It would be scary to go back to the school to investigate for more clues, the crime was already done. They have found the gun and dead bodies. What else can they possible find?
