Boston Bombers Identified; One Dead, Killed by Police; Second at Large

Multiple news sources now report Dzhokar Tsarnaev, age 19, is the man identified by the FBI yesterday as Suspect No. 2. He is the man seen in photos and video as the man who set down a backpack that contained one of the two bombs. 

Suspect No. 1 was killed by police, according to reports. He has been identified as Tamerlan Tsarnaev, the other suspect’s brother, age 26. 
My own search of public records lists both men living at an apartment in Cambridge. Several other individuals ranging in age from their early 20s to mid 40s are listed at the same address.  
US intelligence agencies now will scour their databases for any information about the men and how they got into the country, I’m told by an intelligence source. Multiple news reports have identified the men as legal residents of the US who have been in the country for a year.
