FBI: Have You Seen These Men? Bomber Photos, Video Released

The FBI has released photos and videos of two men suspected in the Boston Marathon bombing on Monday. Lead special agent Richard DesLauriers said the FBI had initially developed one suspect, and has since developed two suspects in the case.

Suspect One is seen in the photos wearing a dark hat. Suspect Two is seen in a white hat, and setting down a bag just in front of the Forum restaurant. The suspects were seen walking together at one point, DesLauriers said. There are also photos and videos of the men apart.

"We know the public will play a critical role in identifying and locating these individuals,"  said DesLauriers. "Somebody out there knows these individuals as friends, neighbors, coworkers or family members of the suspects."

DesLauriers said the FBI is especially interested in photos and videos and accounts from those who were at the Forum resturant prior to the bombing, as one of the suspects dropped a bag there just prior to the explosions.

Finding these two men is the FBI's "sole focus" right now, officials said. The suspects are considered armed and extremely dangerous, DesLauriers said. 

"Do not take any action on your own. If you see these men, contact law enforcement," he said.

You can see all of the photos at the FBI website. Anyone with information about these men can contact officials at boston@ic.fbi.gov or 1-800-CALL-FBI (1-800-225-5324), and select prompt #3.
