BOSTON, MA (RNN) - The FBI released images of two men they believe are responsible for the Boston Marathon bombings and asked for the public's help in positively identifying the suspects.
"At this time, these are the people of interest to the FBI," said Richard DesLauriers, special agent in charge of the FBI Boston field office.
DesLauriers said video helped investigators pinpoint when and where the suspects planted bags they believed contained explosive devices.
The only one observed planting a device is the man the FBI identified as Suspect 2, who was wearing a white baseball cap turned backward and dark clothing.
Suspect 1 was wearing a dark cap, dark jacket and khaki pants.
President Barack Obama said the people of Boston had taught everyone to persevere and "push on" in the wake of the fatal marathon bombings.
