There are new details about the chilling note allegedly written by Boston Marathon bombing suspect Dzhokhar Tsarnaev.
According to prosecutors, this is the note Tsarnaev wrote while he hid from authorities in a boat in Watertown, Massachusetts.
In it, he writes: "God has a plan for each person. Mine was to hide in this boat and shed some light on our actions."
We're also learning the Tsarnaevs used Christmas lights and model car parts to make the explosives.
