Calling himself "Greg" and disguising his voice, at one point in the discussion Lanza compared Travis, the chimpanzee who tore the face off a Connecticut woman in 2009, to "a teenage mall shooter," the Daily News reported Thursday.
The Daily News obtained audiotape of the interview and said two of Lanza's friends vouched that the voice on the tape was Lanza.
"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 during the interview on KWVA, the campus station at the University of Oregon, Eugene. "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."
Danbury State Attorney Stephen Sedensky, who led the investigation into the Dec. 14, 2012, massacre of 20 first graders and six employees at the Sandy Hook Elementary School, said investigators knew Lanza reached out to a radio show, the Daily News reported. Lanza killed his mother, Nancy Lanza, at the home they shared before he went to the school, where he took his life after his killing spree.
Lanza's comments on Dec. 11, 2011, did not throw up any red flags with "Anarchy Radio" host John Zerzan, who told the Daily News he and others remembered the call.
"We remember the call," Zerzan, 70, of Eugene, Ore., said . "The only thing that seemed odd was his voice seemed kind of robotic ... but what he was saying made sense."
Lanza, who police said used the alias "Smiggles" when he posted on online forums concerning mass murder, talked about Zerzan's show in a Dec. 10, 2011, post.
"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.
