Eerie audio footage of Sandy Hook Elementary School shooter Adam Lanza reveals that the 20-year-old called a college radio station a year before the Newtown massacre to claim that a chimpanzee that ripped off a woman’s face wasn’t a monster.

Lanza tried to draw parallels between the story of Travis the Chimp and Norwegian mass shooter Anders Behring Breivik, whom Lanza idolized and emulated when committing the Connecticut school shooting that killed 26 people, including 20 children.

Charla Nash, a friend of Travis’ owner, was severely disfigured when the chimp attacked her in February 2009. Lanza called Anarchy Radio host John Zerzan in December 2011 -- nearly a year to the day before the Sandy Hook shooting -- because he felt Travis’ story was similar to that of Breivik, the Norwegian mass murderer who killed 78 people in July 2011.

Travis’ “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 told Zerzan, according to audio obtained by the New York Daily News. “Travis wasn’t an untamed monster at all. He wasn’t just feigning domestication, he was civilized. He was able to integrate into society. I just ... don’t think it would be such a stretch to say that [Travis] very well could have been a teenage mall shooter or something like that.”

Lanza masked his voice in the call and went by the name “Greg,” but those familiar with the mass shooter said the voice on the call was Lanza’s. “Yes, I think it’s him,” an unidentified friend told the Daily News. “It does sound like something he would say. But he is talking funny.”

“It’s him,” added Kyle Kromberg, one of Lanza’s high school classmates. “I talked to him every day an hour each day from freshman to junior year. He’s a very soft-spoken kid, but very articulate. "As soon as he opened his mouth [in the audio clip], I knew it was him. There’s no voice distinction.”

Zerzan said he didn’t find anything about Lanza’s call alarming. He noted that the call took place a year before Sandy Hook.

“There's nothing there indicating he was considering something so heinous and inconceivable," Zerzan said. "It was a year before Sandy Hook, so no one has any idea what he was thinking a year before…I don't see how anyone could have guessed that with what was said.”
