"Once, in English class at Westfield High School in Chantilly, Va., when the teacher had the students read aloud, Cho looked down when it was his turn, said Chris Davids, a Virginia Tech senior and high school classmate. After the teacher threatened him with an F for participation, Cho began reading in a strange, deep voice that sounded "like he had something in his mouth," Davids said.
"The whole class started laughing and pointing and saying, `Go back to China,'" Davids said."
