Students and teachers return to Plainfield Schools Monday, a little more than two weeks after violent online threats forced the district to shut down early heading into winter break.

Students went back to school in Plainfield and Danville Monday, after more than two weeks of winter break and despite online threats of violence.

The threats, posted on Facebook, indicated today was the day that an attack would happen at Plainfield High School. In fact, nothing violent happened, but there were extra police officers on hand and students had to follow new rules.

Monday morning, students walked the halls at Plainfield High School, books in hand because backpacks weren't allowed. All students also had to be checked for weapons as they entered the building. An online threat posted hours earlier indicated a massacre at the school that "no amount of extra security will be enough."

"Information I've received is that these threats are not credible," said Plainfield Police Captain Jill Lees.

Just before winter break, violent threats made on Facebook led to the closure of both Plainfield and Danville Schools for one day. Another threat days later prompted the evacuation of Perry Crossing Mall in Plainfield. But despite overt threats of detailed violence, nothing happened. Then another taunt: "Police succeeded in buying me more time to take out more people on January 4th". The day came and went peacefully.



Community stunned by Plainfield threats

"This is probably not going to be anything but I can't let go of that 'what if'...'what if',” said Lora Duncan-Terrell, the mother of two Danville High School freshmen. She was upset the school didn't take the kind of precautions in place at Plainfield, although officials say some safety measures in Danville weren't visible.

"Nervous, anxious, we all picked a small town to live in to have that small town security and safety and it's gone. We don't have it anymore," said Duncan-Terrell.

Authorities, including a special FBI Cyber Crimes task force, have been working the case since mid-December but no one has been arrested.

"I guarantee you that the police are doing everything they possibly can in this case, along with the FBI, to investigate these matters and to make sure our students are safe," said Captain Lees.

The extra precautions put into place today at Plainfield High School - specifically not allowing students to carry back packs and having all students checked for weapons, will remain in effect until further notice, according to police. Students' pockets also must be empty when they enter the building - that includes cell phones, change and keys.

"Plainfield students are amazing," said Cpt. Jill Lees with the Plainfield Police Department. "They came in and said good morning to me, told me to have a good day, were ready to learn, also really focused and paid attention and followed all the rules without having backpacks and following all of the rules set in place."



Threat details

The bulk of the threats targeted Plainfield High School and one specific student there. But those threats then mushroomed. The suspect threatened the girl's friends, other students at the school and even threatened to kill police officers who tried to help. The suspect created a Facebook page under the name Brian Kil, detailing his violent and deadly plan. saying. "I spent the entire night making more explosives. I'll be prepared."

That was more than two weeks ago.

Since then, local police have called in the feds, and specifically a team that specializes in internet crimes, to help track down the suspect before any threats are carried out. No arrests have been made in the case.

We talked to a Purdue University cyber forensics expert who trains police to solve computer crimes similar to this case.

"Rarely do they escape, because part of the motivation is they need to keep the attention going," said Dr. Marcus Rogers. "They need that fix."

It appears the suspect has renewed their threats. Police say they are ready, with additional officers on patrol.
