A gut feeling from a New Jersey mom and her tip to dispatch helped Kentucky State Police stop a school shooting before the suspected gunman even left his driveway.

Koeberle Bull woke up to a notification.

"Well, I woke up Wednesday morning to a message," Bull described. It was the most hateful message she'd ever received in her life and it left her fearing for her kids.

"[He was] basically repeating himself about hoping my children would die and be hung because they're black. It was definitely racially motivated, 'you and your monkey children' and using the 'n' word a lot," she said.

Thinking he was local, she called 911; Local for her is New Jersey.

"Other people were able to look him up and go on his page, easily."

The man had blocked her account, but friends found he lived hours southwest in Lawrenceburg, Kentucky. How he got to her Facebook, she didn't know.

Bull said, "Something in the back of my head was like this isn't right, like something's not sitting well."

Trusting her gut she called police in Kentucky. That call put police on his street just in the nick of time. Kentucky State Police, not using his name, told reporters the 20 year old was pulling out of his driveway with hundreds of rounds of ammunition and a detailed plan of attack on two school districts - Anderson County Schools and Shelby County Public Schools.

Bull had no way of knowing when she reported Dylan Jarrell she wasn't just protecting her kids.

"I would hope that someone would, in the same situation, just do the same thing. Because, obviously, you never know. It could be an idle threat or it could be the next mass shooter," Bull said. "It's our future. These kids are our future, my kids, the kids of Lawrenceburg and Anderson County, and we have to give them a fighting shot."

Students in Anderson County will return to school Monday. Additional officers will be at schools in the county as a precaution.
