As if the U.S. and the world isn't shattered enough about the devastating losses of those children and adults, then this article comes on the evening news:

BARTLESVILLE, Okla. - A few hours after a shooter entered a Connecticut elementary school and killed more than 27 people, including 20 children, a Bartlesville high school student was in court – arrested Friday morning for planning his own school shooting, according to police.

Police arrested Sammie Chavez, 18, shortly before 5 a.m. at a residence in west Bartlesville on an arrest warrant for threats to kill.

According to the affidavit, the arrest stems from an investigation that began Thursday with a report made to police by the Bartlesville High School assistant-principal Layne Jones of possible threats toward the school's student body.

Police said a student confirmed that on Wednesday Chavez tried to recruit other students to help him “lure students into the school auditorium where he planned to begin shooting them after chaining the doors shut,” read the report.

The student reportedly told police Chavez threatened that if the student's assisting him did not do as he instructed, he would “not hesitate to kill them and/or himself."

Chavez reportedly told students he would place bombs by the doors in such a manner so when police arrived, he would detonate the bombs as they entered the building, killing them.
