Boston Marathon Bombing

Tamerlan Tsarnaev's Cause of Death Won't Be Released Until Body is Claimed

But we can venture a guess ...

Authorities say the medical examiner has determined the cause of death for Boston Marathon bombing suspect Tamerlan Tsarnaev, but the information will remain private until his remains are released and a death certificate is filed.

His cause of death was determined Monday.

But Tsarnaev's body remains unclaimed. His father has postponed a trip from Russia because of health issues; and it's likely that his mother would be detained for questioning if she decided to return to the U.S.
