The school said Loughner had as many as five run-ins with campus police for “classroom and library disruptions,” and was suspended after college police discovered a YouTube video apparently created by Loughner in which he claimed the college is “illegal.” Rather than return to school, Loughner dropped out, the statement said.

One Pima Community College student, who had a poetry class with Loughner, said he would often act “wildly inappropriate.”

“One day [Loughner] started making comments about terrorism and laughing about killing the baby,” classmate Don Coorough told ABC News, referring to a discussion about abortions. “The rest of us were looking at him in shock … I thought this young man was troubled.”

Another classmate, Lydian Ali, recalled the incident as well.

“A girl had written a poem about an abortion. It was very emotional and she was teary eyed and he said something about strapping a bomb to the fetus and making a baby bomber,” Ali said.
