Authorities have spotted a possible suspect in the Boston Marathon bombing, sources tell CNN. The breakthrough comes based on analysis of security camera footage from a Lord & Taylor store near the site of the second explosion. Other outlets echoed the news, and some, including AP, initially reported that a suspect was in custody. The FBI, however, released a statement insisting that "contrary to widespread reporting" no arrest has been made. It urged the media to check its information more thoroughly. CNN also reported that an arrest had been made, but the network later backtracked.
"The video showed clearly at the site of the second explosion an individual showing up and placing a black bag," John King said on CNN. One of the network's sources say authorities haven't identified the man in the video. In another development, authorities have recovered a piece of circuit board that they believe was part of one of the devices. They also found the lid of a pressure cooker that may have been part of a device, apparently blasted all the way to a nearby roof. More should become clear about the progress on the case at a federal news conference later today. (More Boston Marathon bombing stories.)
