Authorities including bomb experts searched an apartment in Revere, Massachusetts, and removed items, after two deadly bombs struck the Boston Marathon. But investigators remained mum about just how the search may be linked to the bombing investigation.
A law enforcement official said the search was not a suggestion that police may have a suspect. At this point there is no suspect and no leading theory on motive, the official said.
