Investigators told ABC news that a note was found on the boat where Boston bombing suspect Dzhokhar Tsarnaev was hiding.
A source said that the note left by Tsarnaev takes credit for the bombings saying, "when you attack on Muslim, you attack all Muslims."
Dzhokhar also writes that he is not mourning the death of his brother Tamerlan, the other bombing suspect, because he is now a martyr in paradise. It goes on to say Dzhokhar plans to join his brother there.
The boat Tsarnaev was hiding in was in the back of a Watertown yard.
