Brothers Dzhokhar and Tamerlan Tsarnaev are alleged to be behind the bomb attack.
Tamerlan was killed in a shootout with police officers.
His brother Dzhokhar was found by police officers hiding in a boat on Friday morning following a huge manhunt across the city.
His condition has been upgraded from 'serious' to 'fair,' as he recovers from wounds he sustained during a firefight with authorities.
Dzhokhar has reportedly confessed that he and his brother Tamerlan planted the pressure cooker bombs, and were driven to commit the attack by the wars in Iraq and Afghanistan.

The English-language magazine is dedicated to spreading al Qaeda's message, and even includes instructions on how to construct explosive devices.
