Police have credited a New Jersey mother with helping to thwart a man's plans to carry out a mass killing hundreds of miles away in Kentucky.
What are the details?
According to a report Monday by WTXF-TV, Koeberle Bull of Lumberton, New Jersey, recently received a Facebook message from a man she didn't know.
Bull took a look at the message's contents and was shocked to discover crude, harassing language toward her and her children.
The message read, "There's no such thing as white privileged you f***ing autistic f***. I hope your black children gets hung for you being so stupid. ... Act your race."
"I was angry that someone could even think that way about three beautiful children," Bull told WTXF.
She said that she checked out the man's profile and discovered his name was Dylan Jarrell. Jarrell claimed to hail from Lawrenceburg, Kentucky, some 650 miles away from Bull's New Jersey home, and featured a photo of Jarrell posing with a weapon.
Unnerved, Bull contacted the Kentucky state police over the Facebook message.
What happened then?
The Kentucky State Police took Bull's complaint seriously and approached Jarrell, 21, for questioning as he was pulling out of his driveway.
According to the station, an investigation rendered a concerning amount of ammunition and more.
In a statement, the Kentucky State Police said that they discovered "a firearm, over 200 rounds of ammunition, a Kevlar vest, a 100-round high capacity magazine, and a detailed plan of attack" after executing a search on Jarrell's home.
Law enforcement said they believed that Jarrell was on his way to carry out a mass killing and noted that an internet history discovery showed that Jarrell was reportedly researching online how to execute a mass killing at a school.
Commissioner Rick Sanders said that the investigation saved lives.
"There is no doubt in my mind that as a result of his investigation we saved lives," Sanders said. "This young man had it in his mind to go to schools and create havoc. He had the tools necessary, the intent necessary, and the only thing between him and evil and doing evil is law enforcement."
Sanders added, "I can tell you he was caught backing out of [his] driveway."
Authorities charged Jarrell on Monday with making terroristic threats and harassing communications. Jarrell pleaded "not guilty" to making terroristic threats, according to the station.
By the looks of Jarrell's Facebook page, he may have been considering carrying out such a heinous act for quite some time.
In addition to "liking" pages such as "Blue Lives Murder," Jarrell shared photos of quotes like "I'd rather die on my feet than live on my knees" and "Society has failed to acknowledge the monster it has created," the latter being superimposed over an image of the Columbine High School mass murderers.
Also, in May, Jarrell shared a photo of Timothy McVeigh, the Oklahoma City bomber.
Jarrell's apparent Instagram page, "suicidal_idol_," which is private, boasts more than 13,000 followers.
