One year before he killed 26 people at Sandy Hook Elementary, Adam Lanza reportedly called an Oregon radio station and compared a chimpanzee that ripped a woman's face off to a "teenage mall shooter."

"His attack can be seen entirely parallel to the attacks and random acts of violence that you bring up on your show every week, committed by humans, which the mainstream also has no explanation," Lanza said of Travis the chimpanzee, who attacked Charla Nash in 2009.

"I just... don't think it would be such a stretch to say that he very well could have been a teenage mall shooter or something like that."

John Zerzan, the show's host, told the New York Daily News he remembers the call. "The only thing that seemed odd was his voice seemed kind of robotic ... but what he was saying made sense," he said.

Two of Lanza's former high school classmates confirmed to the Daily News that the voice is his. And a user named "Smiggles," which, according to the Connecticut State Police, was Lanza's online alias, posted about calling into the show on the blog Shocked Beyond Belief. The same user mentioned Travis the chimpanzee in several other posts, according to Sandy Hook Lighthouse.
