(NBC NEWS) — The FBI’s lead investigator into the Boston Marathon bombings on Tuesday made a passionate plea for information from the public, saying the “range of suspects and motives remains wide open” as the probe into who might be responsible for the attacks begins.
“Someone knows who did this,” said Richard DesLauriers, the special agent in charge of the FBI’s Boston office. “Importantly, the person who did this is someone’s friend, neighbor, coworker or relative. We are asking anyone who may have heard someone speak about the marathon or the date of April 15 of any way that he or she may have targeted this event to call us.”

DesLauriers told reporters in an afternoon briefing that the FBI has received more than 2,000 tips as of midday Tuesday, and investigators have already vetted some of those. In addition, many people and businesses have submitted photographs and video of the scene near the marathon’s finish line where the blasts occurred.
