Mohamud's friends and classmates describe him as "a chill kid" who played good pickup basketball and wasn't super religious—he even drank beer, though Islam prohibits drinking alcohol. There were some weird incidents, though. For a high school physics project, he taught the class how to use a rocket-propelled grenade launcher.
After high school, Mohamud moved to Corvallis, living off campus and taking pre-engineering classes at Oregon State. KATU news tracked down the article Mohamud wrote for magazine Jihad Recollections.
Numerous articles note that Mohamud withdrew from his normal life over the past couple months. He stopped attending services at his Corvallis mosque, he was registered for fall classes at Oregon State but quit in early October. Friends told the New York Times that Mohamud seemed confused in recent months. The Democrat Herald quotes a classmate, Mo Kim, who said Mohamud was shopping with friends the night before the planned attack.
