Law enforcement sources say the surviving Boston Marathon bombing suspect scrawled a note on the boat where he was captured that said the explosions were retribution for U.S. attacks on Muslims in Iraq and Afghanistan.
The suspect, Dzhokhar Tsarnaev, wrote the note on an interior wall of the boat where he hid as police pursued him April 19, four days after twin blasts killed three people and wounded more than 250 others near the finish line of the annual race. U.S. news media reported Thursday that Tsarnaev called the Boston victims "collateral damage" in the same way that Muslims have been during the two American-led wars.
Part of his note said, "When you attack one Muslim, you attack all Muslims."
Police found Tsarnaev in the boat, which was in temporary storage near a home in a Boston suburb , and began firing when he tried to climb out of the craft. The 19-year-old suspect was seriously wounded as police fired on the boat more than 100 times, but he has survived and is now in a prison hospital awaiting a criminal trial.
Dzhokhar Tsarnaev's older brother, Tamerlan Tsarnaev, died during a shootout with police hours earlier. Another cause of death were injuries suffered when the younger brother drove a hijacked car over Tamerlan as he attempted to escape.
Dzhokhar Tsarnaev faces charges of using a weapon of mass destruction for the bombings.
