CBS’ John Miller broke the story this morning of a note written in pen on the inside of the boat where Tsarnaev lay wounded before he was captured by police:

“Basically the note says that he does not mourn his brother Tamerlan, that Tamerlan was a martyr now and that he was in paradise, that Dzhokhar expected to join him there soon,” Miller said. “That the bombings were in retribution for the US crimes against Muslims in places like Iraq and Afghanistan; that the victims of the Boston bombing were ‘collateral damage,’ the same way innocent victims have been collateral damage in US wars around the world, summing up that when you attack one Muslim, you attack all Muslims.”

The New York Times confirmed the story of the note, buried deep in another story about another Chechen refugee being questioned in the case:

After the death of Tamerlan in a police shootout, Dzhokhar hid inside a neighbor’s boat and wrote with a pen on the inside of the hull that the attack was retribution for the wars the United States waged in Iraq and Afghanistan, according to two law enforcement officials. The note stated generally that an attack on one Muslim is an attack on all Muslims, one official said.

The gist on the aforementioned refugee now on the FBI’s radar:

F.B.I. agents investigating the Boston Marathon bombing have repeatedly questioned Musa Khadzhimuratov, a Chechen refugee and former separatist fighter who says he had a passing social relationship with one of the two bombing suspects. They searched his family’s small apartment here on Tuesday, scouring his computers, subjecting him to a polygraph, and taking a DNA sample.

The hours of F.B.I. questioning in more than a dozen meetings — described by Mr. Khadzhimuratov and his wife, Madina, in an interview — illustrate the bureau’s intensive effort to identify possible accomplices and test its theory that the suspects, Tamerlan and Dzhokhar Tsarnaev, were radicalized and trained on the Web and acted on their own.

But some members and supporters of the small Chechen community in the United States fear that the bureau’s approach may be unduly influenced by Russian authorities who have an interest in using the Boston attack to smear their Chechen adversaries.
