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.
David Mattingly has this Outfront investigation on just how dangerous these devices can be.
(CNN) - The accused Boston Marathon bombers used Christmas lights and model-car parts to make the explosives, prosecutors said in court documents obtained by CNN Wednesday.
"The Marathon bombs were constructed using improvised fuses made from Christmas lights and improvised, remote-control detonators fashioned from model car parts," federal prosecutors said in a motion filed Wednesday. "These relatively sophisticated devices would have been difficult for the Tsarnaevs to fabricate successfully without training or assistance from others."
To obtain explosive fuel for the pressure cooker bombs, the filing says, brothers Dzhokhar and Tamerlan Tsarnaev "appeared to have crushed and emptied hundreds of individual fireworks containing black powder."
Authorities say Tamerlan and Dzhokhar Tsarnaev, 20, planted bombs at the finish line of the 2013 race. Tamerlan Tsarnaev was killed during the manhunt that paralyzed Boston. Dzhokhar Tsarnaev has pleaded not guilty to killing four people and wounding more than 200.
(CNN) – "We just watched the marathon and then boom."
On April 15, Jarrod Clowery, a 35-year-old carpenter and his three friends were at the Boston Marathon when they heard an explosion. Clowery and his friends were only a few feet away from the second explosion when it went off. While they all survived, each of his friends lost a leg in the blast.
It's been six months since three people were killed and more than 260 were injured.
CNN's Erin Burnett spoke to Clowery about his life after the bombings.
"I had a bit of a tough time when I got out of the hospital readjusting to normal life," Clowery says. "But recently in the past few months, I've been getting healthier."
Clowery was severely injured by the bomb that went off outside The Forum restaurant. All of his limbs were hit by shrapnel, hearing in his left ear has diminished by 20% and he's lost hearing altogether in his right ear.
Burnett asked Clowery how his friends are dealing with their injuries:
"One of my friends said we're going to be normal; it's just going to be a different kind of normal."
"You know those guys, they can't just get up and go like they did. And they still got a lot of healing to do."
Clowery's three friends each lost their leg.
"I'm walking and I'm talking and I get to do some great things to help people," Clowery says. "My friends they got a lot worse injuries then I did but they're in good spirits also."
Since leaving the rehabilitation facility in May, Clowery's days have been filled with working out at the gym, coaching his son's football team and starting a foundation called Hero's Hearts foundation.
Clowery says the foundation will recognize what he call 'real heroes' - first responders who don't get the recognition they deserve.
The One Fund Boston, a nonprofit created to benefit the victims of the Boston Marathon bombings, gave Clowery $735,000.
Clowery has used the money to help a few friends, his son and his foundation.
"I want to be very careful with that money to make sure that it goes out the same way that it came in - that's positive."
Clowery tells Burnett he doesn't think about Tamerlan and Dzhokhar Tsarnaev, the suspects behind the Boston marathon bombings.
"Their story is their story," Clowery says. "It happened, it's got to be reported and I just choose not to get involved. I think, me and the other survivors have a chance to change things a bit by not giving them any recognition."
Clowery tells Burnett he is not planning to follow the trial.
Clowery says he can't run away from what happened. Every time he tells his story of the bombing, he replays that moment in his mind - the moment he was on top of a railing and was hit by the blast.
"We can't change what happened, but we can expose the good things that have happened whether it's my foundation, or the progress that some of the other survivors are making."
Newly released court documents show that suspected Boston bomber Dzhokhar Tsarnaev suffered multiple gunshot wounds during a shootout with police on April 19th.
The most severe injury was a gunshot wound on the left side of his face.
There are also questions surrounding the death of an acquaintance of Dzhokhar 's older brother Tamerlan.
Ibrahim Todashev was killed by the FBI in May while agents and police questioned him about his connection to the elder Tsarnaev.
Todashev's father is convinced the FBI is hiding something and is demanding answers.
Susan Candiotti is OutFront with the story.

New details are emerging about Katherine Russell, the widow of Boston marathon bombing suspect Tamerlan Tsarnaev, who was killed in a police shootout on April 19th.
The American-born 24-year-old has not been arrested, but the FBI hasn't ruled out the possibility that she was a co-conspirator in the Boston marathon bombing or, as one law enforcement source put it, "an abused enabler."
