A high school classmate of Mangione’s told Fox News Digital that he “seemed like a smart kid” who “always did the right thing.” He “always had a smile on his face. He never really felt like he was socially awkward. That’s why I’m really surprised,” the classmate said.

“I graduated in 2015, he graduated in 2016,” this classmate added. “It’s crazy how people can change 10, 9 years later.”
