Bull, a white man, told the Washington Post that his Facebook profile picture showed him with his three children aged 8, 11 and 16; but she does not know how or why Jarrell viewed her page or sent her a private message. She said that she had no connection with Kentucky – no family members or friends in this country. It is not known if Jarrell knows anyone in his state.

She told CBS WKYT's affiliate that after Jarrell had sent him the Facebook message, he had blocked his account and therefore could not view his personal information. But she asked friends to tell her where the man lived so that she could contact the authorities there.

"Something in the back of my head made me think that it was not right – for example, something badly seated," she told the channel.

According to an image of the message that Bull has provided to The Post, it is written: "There is no white privilege. . . I hope your black children will be hanged for your stupidity. They all have the same rights as we have now, so please, your monkey children will die. "

Bull said her husband, who died in 2012, was black.

She reported the message to the police, she said, because she was worried about her family. "I was protecting my own children and defending what was right," she said on Tuesday.

She was "shocked" to hear what police learned.

After receiving the complaint last week, Kentucky police investigators discovered that Jarrell, a white man, had already been questioned by the FBI about threats to a Tennessee school.

When Kentucky soldiers went to interrogate him on Thursday, he left his home in Anderson County, Kentucky, with a gun and ammo, a Kevlar vest, and a "detailed attack plan." ", according to the state police.

The authorities contacted the school districts of Anderson and Shelby counties "and collaborated with the administrators to define a plan of action." The Anderson County Schools were closed Friday; The Shelby County School District, which is on a fall leave, has suspended all of its activities at Shelby County High School.

The police did not explain why Jarrell could have targeted the districts.

Michael Clark, director of student services for Shelby County Public Schools, said that Jarrell was last enrolled at Shelby County High School in 2013, but that he could not not share more details because of the ongoing investigation.

The superintendent of the Anderson County Schools, Sheila Mitchell, stated that Jarrell had not been enrolled in the school district, with the exception of a course of examination of the General Education Development Program (GED) in 2016. Jarrell completed his general education program last year, said Mitchell, adding that no behavior had been reported concern. when he was in the program.

So far this year, there have been at least 17 shootings in schools.

Officials from both Kentucky school districts said that they were "grateful" to the state police – as well as to the New Jersey mother who brought to their attention a potentially horrible situation .

"It was a horrible situation, but the situation could have been much worse," Mitchell told The Post. "We are very grateful to him. I believe his efforts to protect his children have protected many other Kentucky children. "

Bull, the mother, said that the experience had been "humiliating".

"I just hope more people will express themselves," Bull said. "We must give our children a fight, otherwise our children will die, and our future will die with them."
