One year before he killed 27 people, including 20 children at an elementary school in Newtown, Conn., Adam Lanza placed an ominous phone call to an Oregon radio station.

In the call, which took place Dec. 11, 2011, Lanza tells “Anarchy Radio” host John Zerzan that a comparison can be made between Travis the chimp, a domesticated primate who tore a woman's face off in 2009, and a "teenage mall shooter."

The call can be heard in the clip above.

"[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 said in the clip obtained by the New York Daily News. “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.”

During the call, the Daily News reports, Lanza made efforts to disguise his voice, but two of Lanza's friends from high school recognized Lanza in the audio recording. The Newtown shooter told the station his name was "Greg."

"We remember the call,” radio host Zerzan, said. “The only thing that seemed odd was his voice seemed kind of robotic ... but what he was saying made sense.”

The News' story comes days after CBS reported that Lanza's father will help provide his son's medical records to the state commission investigating the shooting.

In November, Connecticut's Division of Criminal Justice released a report documenting every step Lanza took as he killed indiscriminately before taking his own life.
