Cops: Teen Held After Vowing School 'Killing Spree' On YouTube

Sawed-off shotgun later recovered during search of Arizona boy's home

PHOENIX — A 14-year-old boy was arrested Tuesday for threats made over the Internet to "go on a killing spree" and then commit suicide at his former middle school, authorities said.

The teenager was taken into custody without incident at his home after posting the threats in the comments section of a YouTube music video for the hit song "Pumped Up Kicks," according to Sergeant Jessie Spurgin, a Maricopa County Sheriff's Office spokesman.

"He gave out a specific place and time for when it would happen," Spurgin said. "That made it a little more credible in our eyes."
