The father of the suspects in the Boston Marathon bombing claims that his son who is still on the loose is a smart and accomplished young man.

Anzor Tsarnaev spoke with The Associated Press by telephone from the Russian city of Makhachkala on Friday after police said one of his sons, 26-year-old Tamerlan, had been killed in a shootout and the other, Dzhokhar, was being intensely pursued.

"My son is a true angel," the elder Tsarnaev said. "Dzhokhar is a second-year medical student in the U.S. He is such an intelligent boy. We expected him to come on holidays here."
