With Boston Marathon bombing suspect Dzhokhar Tsarnaev in police custody at Beth Israel Deaconess Medical Center and his brother and fellow suspect Tamerlan Tsarnaev dead after a shootout, many questions now focus on how these two young men arrived at this point.
Back now to our coverage of the tense night and police activity that brought an end to the manhunt for the second Boston Marathon bombing suspect. Franklin Street in Watertown was the epicenter of that massive search. Police and SWAT teams took over the suburban neighborhood looking for 19-year-old Dzhokhar Tsarnaev. Keith Glavish lives nearby. He was in his house while the search unfolded. Thanks for being with us.
People who knew Dzhokhar Tsarnaev just have a hard time squaring the man they knew, with the violence in Boston. Sierra Schwartz went to Cambridge Rindge and Latin high school with the suspect, who's now in custody.
SIERRA SCHWARTZ: The Dzhokhar that I knew at the time was friendly, quiet but not in a - alarming way. He was just - you know, soft-spoken but very - you know, funny, very sweet, wouldn't harm a fly; someone that you would want to talk to.
The Boston Marathon bombing suspects are ethnic Chechens with links to the volatile North Caucasus region of Russia. Moscow's reaction to that fact appears to be as complex as the region's turbulent history.
