The death of radical Muslim Tamerlan Tsarnaev and capture of his brother Dzhokhar ended four days of terror after the two set off a pair of deadly bombs during the annual Boston Marathon.

When the billowing smoke finally cleared, three people were left dead and 264 others were wounded, many of whom lost their limbs.
"I saw at least six to seven people down next to me," said doctor Allan Panter, who was standing near the finish line. "One lady expired. One gentleman lost both his (lower) limbs."
Using images from video cameras near the race, the FBI identified their suspects as the Tsarnaev brothers who'd come to America seeking political asylum from the turmoil in their native Chechnya.
Despite finding a good life in the U.S., the ingrates betrayed their new homeland. The FBI asked the public's help in finding them.
