1,000 Words: Tsarnaev’s letter

Hiding from police in a boat hours after he and his brother planted the Boston Marathon finish line bombs, Dzkhokhar A. Tsarnaev wrote in pencil that he believed his Islamic faith permitted the killing of innocents in defense of other Muslims, a police officer testified Tuesday.

This undated forensics photograph provided by the U.S. Attorney's office and presented as evidence during the federal death penalty trial of Boston Marathon bombing suspect Dzhokhar Tsarnaev Tuesday, March 10, 2015, in Boston, shows handwriting on the bullet-riddled, blood-stained wall of a boat. The prosecution presented the photo as evidence of the handwritten note found inside the boat where Tsarnaev was captured April 19, 2013 in Watertown, Mass., four days after the bombings.
