An Ohio boy who took his own life in a middle school bathroom had planned a school shooting before changing his mind at the last minute.

The 13-year-old boy, Keith Simons, had made several notes in his phone, detailing his plan.

“I’ve been planning this for a few weeks and thought about it a few months, I will never be forgotten. I’ll be a stain in American history ... it’s going to be so (much) fun. They won’t expect a thing,” one statement read.

In the video below, Jackson Police Chief Mark Brink outlined the timeline that led to the student's death, saying that another student who was in the bathroom before the incident knew of Simon's plan and immediately sought help.
