Officers took the youth into custody Friday. The arrest came after an investigation at THS.

During the course of the investigation, it was determined the suspect told the victim she would be the first he was going to kill. The threat happened during the sixth hour of class Friday, reports said.

The officers were responding to the high school because of contents of his Facebook page. Facebook is a social networking Web site.

THS principal Jamie Carlisle declined to comment on the student, citing student privacy issues.

However, he did say that the incident did not occur on school grounds. Rather, the situation was brought to his attention, and he then contacted the authorities.

“I had an active role because I care about kids,” Carlisle said.

The student had posted comments on his Facebook page that read he hated school and he was going to shoot it up and kill more than 13 people. The suspect told deputies the posting was a joke and he would delete the comments.

The investigation came one day after students in grades 7-12 attended a Rachel’s Challenge assembly. Rachel’s Challenge is an organization that was created after the 1999 Columbine High School shootings in Colorado. The organization was named after Rachel Scott, who was the first person killed during the tragedy. The organization challenges others to show compassion and kindness toward others, something that Scott was known for.

The day of the tragedy, 12 students and a teacher were killed – the same total number the THS student vowed to eclipse with his threat.

Attempts by The Mirror to find the student’s Web page online were unsuccessful.

In most cases, full Facebook pages may only be viewed by fellow members who are approved by the page’s “owner” as a “friend,” thus allowing them access to the information.

Sheriff’s officers found the suspect at his home in Tonganoxie and he was taken into custody. The suspect was booked into the Juvenile Detention Facility in Leavenworth without incident Friday, reports said.

Bob Doyle at the detention facility said Tuesday that the 15-year-old was released, by order of the county attorney’s office, to a family member about 10:10 p.m. Saturday.
