BOSTON (Reuters) - No organization has claimed responsibility for the bombings at the Boston Marathon and the FBI currently has no "definitive information" on suspects, Richard DesLauriers, the agent running the investigation, said on Tuesday.
"At this time there are no claims of responsibility. The range of suspects and motives remains wide open," said DesLauriers, the FBI special agent in charge in Boston. "We don't have any definitive information regarding a suspect or suspects. It could be a person, it could be persons."
