BOSTON, Mass. — Boston Marathon bombing victims were collateral damage in a strike meant as payback for U.S. wars in Muslim lands, the surviving suspect wrote in a message scribbled on the boat where he was found hiding, a law enforcement source told CNN Thursday.
In the message, Dzhokhar Tsarnaev also proclaimed that an attack on one Muslim is an attack on all and said he would not miss older brother Tamerlan Tsarnaev — who died after a firefight with police three days after the bombing — because he would soon be joining him, according to the source.
The writing on the inside of the boat dovetails with what Dzhokhar, 19, told investigators questioning him in a Boston hospital room shortly after his capture, the source said.
CNN has previously cited U.S. officials in reporting that Dzhokhar said U.S. involvement in Afghanistan and Iraq were motivating factors behind the April 15 attack, which killed three people and wounded 275.
