Bombing suspect's parents: Trip had 'nothing to do with militants'

The parents of Tamerlan Tsarnaev have insisted that he went to Dagestan and Chechnya last year to visit relatives and had nothing to do with militants operating in the volatile part of Russia.

His father said he slept a lot of the time but the Boston Marathon bombing suspect could not have been immune to the attacks which savaged the region during his six-month stay.
