Lawrenceburg, KY – A Kentucky state trooper was credited with preventing a school shooting on Thursday just as the would-be gunman was allegedly heading out to conduct his murderous mission.

“I can tell you he was caught backing out of his driveway with the tools he needed to commit this heinous act,” State Police Commissioner Richard Sanders told reporters at a press conference, according to WKYT.

When police arrested 21-year-old Dylan Jarrell in his driveway on Oct. 18, he was carrying a gun, 200 rounds of ammunition, a Kevlar vest and a plan of attack for a school shooting with him in his vehicle.

Authorities said that the investigation began when Kentucky State Trooper Josh Satterly received a call from a New Jersey woman who said she was being harassed by Jarrell on Facebook, WKYT reported.

“The call came in from a victim to Trooper Satterly. He looked into this thing thoroughly,” Commissioner Sanders said.

Koeberle Bull told police she didn’t know the man who called her a “wanna-be” black woman and said he hoped her children would be hung, The Washington Post reported.

Bull told The Washington Post her profile picture featured her with her three children, ages eight, 11, and 16, but that she had no connection whatsoever to Jarrell. She is white, and her husband, who died in 2012, was black.

Jarrell blocked Bull after sending the racially-charged messages, so she had other friends creep his page to gather as much info as possible to give to the authorities.

Afraid for the safety of her biracial family, Bull contacted the police department in Lumberton Township, New Jersey for help.

Then she got in touch with the Kentucky State Police and told them her story.

“There’s no such thing as white privileged… I hope your black children gets hung for you being so stupid. They have all the same rights we have now a days so please you and your monkey children go die,” the message read, according to The Washington Post.

State and federal law enforcement interviewed Jarrell at his home, and he admitted he had sent “racially-motivated” messages to the woman, according to the citation for his arrest.

Police searched his phone and found messages that included “threats of bodily harm against multiple persons at a school,” the Louisville Courier-Journal reported.

Investigators also discovered a Facebook profile that featured Jarrell holding an “assault-style weapon.”

“He had the tools necessary, the intent necessary, and the only thing that stood between him and evil is law enforcement,” Commissioner Sanders told reporters.

There was also a Twitter account called “Suicidal_idol_” under Jarrell’s name that had a cover photo with the statement, “society has failed to acknowledge the monster it has created,” the Louisville Courier-Journal reported.

He was arrested at the scene and charged with terroristic threatening and harassing communications, WKYT reported.

“There’s no doubt in my mind that as a result of this investigation, we saved lives,” Commissioner Sanders said, crediting Trooper Satterly’s aggressive investigation.

Anderson County Schools were closed on Friday as a result of the threat, although police have not said exactly which schools had been targeted.

Superintendent Sheila Mitchell said that Jarrell had received his GED through Anderson County Schools in 2017.

But he attended Shelby County schools until his freshman year of high school, the Louisville Courier-Journal reported.

Kentucky State Police said Jarrell had been questioned by the Federal Bureau of Investigation in May regarding social media threats he made to a school in Tennessee.

Jarrell was being held at the Shelby County Detention Center on a $50,000 bond, according to the Louisville Courier-Journal.
