From the Huffington Post:
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, postponed from the previous evening.
The much anticipated announcement follows a day dominated by misreportingthat police were ready to announce an arrest in the case. By Thursday morning, however, most outlets said the photos in question were circulating through law enforcement agencies and would soon be available to the public.
