LISTEN: Sandy Hook shooter Adam Lanza called a radio station to compare a chimp to mall shooters

This undated identification file photo shows former student Adam Lanza, who authorities said opened fire inside the Sandy Hook Elementary School in Newtown, Conn., on Friday, Dec. 14, 2012, killing 26 students and educators.

A new report from The New York Daily News suggests that Sandy Hook shooter Adam Lanza called an Oregon radio station in 2011 and discussed mass killings, comparing a mall shooting to the infamous case of Travis the Chimp mauling a Connecticut woman.

The New York Daily News obtained audio of the 7-minute call and verified the authenticity of Lanza's identity with two former classmates of Lanza's, who say that it sounds like Lanza is trying to disguise his voice during the call.

Using the name Greg and apparently taking pains to disguise his voice, Lanza weighed-in on mass murder by comparing “a teenage mall shooter” to Travis, a chimpanzee who became infamous after ripping the face off a Connecticut woman in 2009.

In doing so, Lanza provided a frightening look not seen thus far into the twisted logic and troubled mind of the 20-year-old killer.

“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 says of Travis at one point.

Additionally, police say that Lanza used the online alias "Smiggles" when venturing into forums to discuss mass killings. "Smiggles" discussed his appearance on the Oregon radio show in a post authored on December 11, 2011.

I’m really surprised that I haven’t been able to find anything he’s written or said about the incident, considering how often he brings up random acts of violence,” Smiggles wrote before calling into the show. “It seems like Travis would be a poster-chimp of his philosophy.”

A day after Greg called into the radio show, Smiggles posted this appraisal:

“It didn’t go as horribly as I anticipated. I wish that I hadn’t spoken nonstop about Travis for so long, but I didn’t want to seem crazy by randomly bringing up a chimpanzee for unknown reasons.
