A law enforcement official says the suspect being hunted in the Boston Marathon bombing is in a boat stored in a Watertown, Mass., neighborhood.
The official said he was briefed on the situation and spoke on condition of anonymity because he's not authorized to discuss it publicly.
The official does not know if Dzhokhar Tsarnaev is dead or alive.
Authorities are telling residents of the area to stay indoors.
The burst of activity came at the end of a tense day in and around Boston, and less than an hour after police announced that they were scaling back the hunt because they had come up empty-handed following an all-day search that sent thousands of SWAT team officers into the streets and paralyzed the metropolitan area.
