Authorities released photographs of two individuals -- identified as "Suspect 1" and "Suspect 2" -- wanted in connection to the pair of deadly blasts at the Boston Marathon finish line Monday.
The images, revealed from behind two black poster boards, show the two individuals walking through a crowd near Boylston Street moments before the terror attack, which killed three people and wounded at least 180 others.
"These images should be the only ones that the public should use to assist us," FBI Special Agent Richard DesLauriers said in a Thursday press conference, discouraging people from paying attention to unofficial photos published in the mainstream media and on the Internet.
"The only photos that should be officially relied on are the ones before you," DesLauriers said.
"Suspect 1" is wearing a dark hat, "Suspect 2" is wearing a white hat.
"They appear to be associated," DesLauriers said. "Suspect 2" dropped a backpack at the site of the second explosion in front of the Forum restaurant and proceeded west, he added.
