An Idaho school was placed on lockdown after a student threatened to "kill all the girls" because none of them would send him nude photos.
A 15-year-old boy was charged with one count each of threatening violence at a school and telephone harassment in connection with the threats -- which spread quickly across social media Wednesday morning and were then reported to officials at the Pocatello/Chubbuck School District.
Police immediately initiated a controlled access code at Highland High School as officers investigated the threat.
“Some kid who was having attention problems with specifically the cheerleaders, didn't get nudes," said student Isaac Gomez. "He was asking for some inappropriate things."
The teen allegedly posted the threats on both Facebook and Twitter, saying he intended to bring a gun to school and kill all the girl students, and shared detailed plans for how he would enter the school and eventually kill himself in the weight room.
A screenshot posted online by KIDK-TV appears to show a text message conversation between the teen and a friend who tries to talk the boy out of his violent plot, which he intended to carry out about 9:30 a.m. Friday.
"(I'm) serious I have a 12 gauge shotgun and a 9 mm pistol I will bring and start killing everyone," one message said. "I also have hunting knives I can bring."
Local media reports did not indicate whether the teen actually had any weapons or how he might have gained access to them, and no adults have been charged at this point.
The boy also used his Twitter account to repeatedly harass other Highland students, mostly girls, and other posts threatened to harm President Barack Obama and made racist remarks about black people.
Additional messages between the teen and his friend suggested his motivation for wanting to kill girls at his school.
"This," the friend texted, "Over freaking nudes? Dude."
"Because no one will give any to me," the teen complained. "Every one hates me. And I hate (one particular girl). And I will kill myself after."
The boy's friend appears to take the threat seriously, particularly after he says he hopes classmates have wills in place.
"We're kids," the friend says. "Nothing valuable. Except our lives so leave us alone."
