PROVIDENCE, R.I. (AP) -- Relatives of the dead suspect in the Boston Marathon bombing will claim his body now that his wife has agreed to release it, an uncle said as officials in both Washington and Russia deepened their investigations into him and his ties.

The body of Tamerlan Tsarnaev, 26, has been at the medical examiner's office in Massachusetts since he died after a gunfight with authorities more than a week ago.

Amato DeLuca, the Rhode Island attorney for his widow, Katherine Russell, said Tuesday that his client had just learned that the medical examiner was ready to release Tsarnaev's body and that she wants it released to his side of the family.
