State police commissioner Richard Sanders told WKYT that police reached Jarrell’s home just as he was backing out of his driveway “with the tools he needed to commit this heinous act.”

During a search, investigators discovered that Jarrell had a firearm, more than 200 rounds of ammunition, a Kevlar vest, a 100-round high capacity magazine and a detailed plan of attack on two Kentucky school districts.

“There’s no doubt in my mind that as a result of this investigation, we saved lives,” Sanders told WKYT. “He had the tools necessary, the intent necessary, and the only thing that stood between him and evil is law enforcement.”

Schools in Kentucky’s Anderson County canceled classes on Friday, Oct. 19, citing “a credible threat of violence” in their Facebook post.

As for Bull, she said she hopes that someone in the same situation would do the same thing “because, obviously, you never know.”
