Authorities investigating the bombings at the Boston Marathon warned on Tuesday not to expect immediate answers about who was behind the explosions that ripped apart the race's finish line Monday afternoon. Even as the public poured in tips -- more than 2,000 by noon on Tuesday -- and the FBI vowed to "go to the ends of the Earth," in its search, authorities speaking at an evening press conference in Boston did not announce any major break in the case. "The investigation is in its infancy," said Richard DesLauriers, the FBI's special agent in charge. "We are doing this methodically ... yet with a sense of urgency."
