The FBI asking the public for its help as it released surveillance video and photos of two men. Investigators say they want to question the pair about their roles in Monday's bombings at the Boston Marathon. YNN's Michael Herzenberg has more.
BOSTON -- Take a good look. The FBI believes these two individuals planted Monday's bombs that killed three people and wounded more than 170 others.
"We consider them to be armed and extremely dangerous. No one should, except law enforcement," said Richard DesLauriers, FBI Boston Special Agent in Charge.
The feds say images show suspect one and suspect two walking together on Boylston Street through the marathon crowd towards the finish line.
DesLauriers said, "These images should be the only ones, I emphasize, the only ones, the public should use to assist us."
Suspect one wears a dark hat. Suspect two, a white hat. Investigators say suspect two placed a backpack at the site of the second explosion in front of the forum restaurant.
DesLauriers said, "It was shortly before the bomb blast went off. Within minutes."
Suspect two walks west on Boylston Street among runners, spectators and volunteers.
"It was like a war zone,” this man said. “Windows blown out of the buildings."
This man says he volunteered at the Boston Marathon for more than two decades, but after seeing the carnage, he doesn't sleep much anymore.
"What they have, I hope they catch him or her or them and soon there were too many people effected by that," he said.
