Boston suspect's ex-teachers in Kazakhstan say he was normal teen, not a star student

Former teachers of one of the students from Kazakhstan arrested in connection with the Boston Marathon bombings describe him as an easygoing teenager not the least interested in Islam who distinguished himself mainly by his failing grades in math and science.

Dias Kadyrbayev was a university friend of bombing suspect Dzhokhar Tsarnaev. He and another 19-year-old student from oil-rich Kazakhstan, Azamat Tazhayakov, have been charged with trying to destroy evidence by disposing of a backpack and laptop computer taken from Tsarnaev's dorm room after learning he was a suspect in the attack.

At the Kazakh school Kadyrbayev attended when he was 14 and 15, deputy principal Yuri Dovgal said Friday: "He wasn't a star student, but he wasn't a hooligan. He was a normal teenager."
