CNN has obtained a new video showing security camera footage of the Tsarnaev brothers working out at a martial arts gym 72 hours before they are alleged to have perpetrated the Boston Marathon bombings.
The bombings drew new attention to the murder of Tamerlan's only American friend. But now evidence suggests his little brother also may have been involved.
The bombs used in the Boston Bombing were built inside older brother Tamerlan Tsarnaev's apartment that he shared with his wife and child.
Panasenko was charged with carrying home made explosives on a NJ Transit train, but insists that they were just fireworks.
The remotes didn't have a long range and had to be used in close proximity to the bombs.
#FreeJahar is a Twitter hashtag that was started to help free Dzhokhar Tsarnaev, the suspect in custody over the Boston Marathon bombings.
