As investigators struggle to nail down Dzhokhar Tsarnaev’s psychological state when he allegedly carried out the Boston bombings, a new report from CBS suggests that the 19-year-old confessed to the crime in a note before he was captured in the boat where he was hiding. The full text of the item, which was reportedly scribbled onto the side of the boat, has not been released. But one line, published by CBS, alludes to getting revenge for attacks on Muslims. “When you attack one Muslim, you attack all Muslims,” it reads. Dzhokhar made mention of his deceased brother Tamerlan in the note as well, calling him a "martyr in heaven." Despite the relevance of the message, authorities say it cannot be used in the case against Dzhokhar.
