New video shows teams of FBI, federal and police investigators scouring the boat in the backyard of a Watertown, Mass. residence where the manhunt for Boston bombing suspect Dzhokhar A Tsarnaev ended on Friday night. 

The homeowner alerted law enforcement after he spotted what he believed to be a bloody body in the boat. Infrared and thermal technologies helped law enforcement confirm Tsarnaev was, in fact, hiding inside. A standoff with police finally resulted in Tsarnaev being taken into custody and rushed to a hospital where he remains in serious condition.
