An 18-year-old Tucson terror suspect has entered a plea of not guilty. Mahin Kahn was charged with crimes involving a pipe bomb and a plot to blow up a motor-vehicle office in Phoenix. Other court documents linked the 18-year-old to plans for an attack on an Air Force Recruitment Center in Tucson.
We're now hearing from a fourth former classmate of Khan's who is speaking exclusively to Nine On Your Side.
He says he saw signs of Anti-American behavior as early as the second grade. The pattern shows Khan threatening his peers in school for about a decade. The names of the students have been redacted for their safety.
Four different students have four very similar memories.
"He would torment me a lot, he would bully me," said a former elementary school classmate. "He would threaten to blow up the school, he would threaten to kill people, he would threaten to kill me a lot."
"He just went on to say how the military was evil," said a former high school classmate. "How he wanted to grow up to kill all the military and the marines."
"At one point he went as far as to stay that what Hitler did was good," said a third classmate. "He told me he did not like the Jewish people."
"He would mention stuff about the army and how he wanted to pay them back," said a fourth classmate. "He'd talk about the military and how they were cowards."
Three of Mahin Khan's former classmates from Catalina Foothills High School and now one from his elementary school spoke exclusively to Nine On Your Side.
The most recent student we spoke to attended Khalsa Montessori school when the now terror suspect was second grade.
"On 9/11 it's pretty traditional for schools to discuss how terrible the attacks were and what happened. I remember very vividly that this kid drew on a piece of red construction paper with a black crayon a picture of himself flying a plane into the Empire State Building saying, "this is what I want to do. I want to destroy the empire state building."'
The student says he was victimized by Khan so badly that his parents pulled him out of the school just a few months after meeting him.
"He picked on me he would physically touch me, he would assault me so it did make me feel unsafe."
He says the school did nothing to stop it.
"My parents and a lot of other parents whose kids were being harassed by Mahin would complain to school administration about it. It seemed pretty obvious that the school was refusing to do anything."
In documents from the Arizona Attorney General, Khan admitted to being a support of ISIS and the Pakistani Taliban.
Khans former peers say they saw it coming.
"Eight-year-olds don't tend to talk about becoming terrorists and killing people and blowing stuff up. Eight-years-olds don't even seem to have that kind of knowledge of that stuff. I did have a sinking feeling deep down that he was going to attempt something in his lifetime."
