Update On Recent Boston Bombing Arrests

A new arrest in the Boston Marathon bombings case is casting a light on communication problems at the Homeland Security Department. One of the three people arrested yesterday was allowed to return to the United States from Kazakhstan despite not having a valid student visa. Azamat Tazhayakov was a classmate of suspect Dzhokhar Tsarnaev at the University of Massachusetts Dartmouth. Tazhayakov left the United States in December. The university dismissed him for academic reasons. His student-visa status was terminated. A Homeland Security spokesman said when Tazhayakov arrived in January, Customs and Border Protection did not know Tazhayakov's status had changed. DHS is reforming the student visa system to give Customs access to all relevant student visa information.
