There is a lot of speculation about what the FBI will say during the press event, much of it centering on a surveillance video and photos the bureau says it has that show an individual it is interested in speaking with.

Wednesday was a day of endless speculation by media outlets, as CNN, the Boston Globe and others reported that sources informed them that a suspect had been arrested in connection with the Boston Marathon bombings, but the outlets backtracked later as the FBI and Boston Police Department vehemently denied the reports.

“Contrary to widespread reporting, no arrest has been made in connection with the Boston Marathon attack," the FBI wrote in an official statement. "Over the past day and a half, there have been a number of press reports based on information from unofficial sources that has been inaccurate. Since these stories often have unintended consequences, we ask the media, particularly at this early stage of the investigation, to exercise caution and attempt to verify information through appropriate official channels before reporting.”

Shortly after the networks retracted their reports of an arrest Wednesday afternoon, Reuters reported that a law enforcement source said that in fact investigators have identified a suspect in a security video taken near the scene of the explosions but that there has yet to be an arrest made.

As of Thursday afternoon, authorities had not released the security footage or photos of any suspects, though the New York Post did run a photo on the front page Thursday morning of two individuals that it said authorities were looking for, an assertion that came under heavy criticism as the men turned out to be highly unlikely terror suspects.
