Prosecution rests in penalty phase of Boston bomber trial

BOSTON (AP) - A video played Thursday at the trial of Boston Marathon bomber Dzhokhar Tsarnaev showed a mother crouched over her 8-year-old son as he lay dying on the sidewalk, a scene prosecutors hoped would linger in jurors' minds while they determine whether Tsarnaev lives or dies.

Prosecutors rested their case after playing the video during the testimony of a man who lost his leg in the bombings, and jurors watched as the mother pleaded with her little boy.

"I heard 'please' and 'Martin' being uttered by Denise Richard," said Steve Woolfenden, who was lying on the pavement next to Martin and his mother after the second bomb exploded. "Just pleading with her son."

The boy bled to death.

Prosecutors presented the testimony and searing images to give the jury one last reminder of the brutality and heartbreaking consequences of the bombings before the defense presents its case next week. Prosecutors argue Tsarnaev, now 21, should be executed for his crimes, while his lawyers say his life should be spared because his late older brother, Tamerlan, was the mastermind of the attack.
