Boston Marathon Bombing Suspect Photos & Video Released By FBI

The FBI released video and photos Thursday afternoon of the two suspects it is focusing on in connection with the Boston Marathon bombing.

Richard DesLauriers, FBI special agent in charge for Boston, only identified the men as “Suspect 1” and “Suspect 2.” Suspect 1 was wearing a dark hat while Suspect 2 was shown wearing a white hat and set down a backpack at the site of the second explosion in front of the Forum restaurant. The suspects are considered “armed and dangerous.”

DesLauriers encouraged anyone who was near the restaurant at the time of the explosion to contact the FBI.

He said both suspects “appear to be walking together to the marathon crowd on Boylston Street near Gloucester Street.”

DesLauriers said the public’s help will be crucial to the investigation and apprehension of the suspects. He said the two men are the only persons of interest in the case for now.

“For more than 100 years, the FBI has relied upon the public for its eyes and ears,” he said. “We know the public will play a critical role in locating these individuals.

“No bit of information, no matter how small or unseemingly inconsequential, is too small for us to see,” he added.

Should anyone encounter the suspects, they should call authorities, DesLauriers said.

“We consider [the suspects] to be armed and extremely dangerous; no one should approach them, no one should attempt to apprehend them except for law enforcement,” he said.

Anyone with information on the suspects were told to call 1-800-CALL-FBI or submit tips to bostonmarathontips.fbi.gov.

The revelations of the suspects came after a frantic day Wednesday, when CNN and the Associated Press had to retract reports that a suspect was in custody. The FBI put out a statement later in the day reiterating that no arrests had been made in the case.

The explosions killed three people: Martin Richard, 8, of Boston; Krystle Campbell, 29, of Arlington, Mass.; and Boston University graduate student Lingzi Lu of China. More than 180 people were injured in the blasts; many of them lost limbs in the attacks.

A pair of bombs detonated 18 seconds apart near the finish line of the Boston Marathon in Copley Square. Investigators determined that the bombs were housed in pressure cookers and contained nails and BBs.
