A suspect has been identified in the Boston Marathon bombing, an unidentified law enforcement source tells CNN.
The station reported on a live feed that officials believe a video from a department store and a TV station helped identify the suspect. It's yet unclear whether a suspect has been located and apprehended or just identified.
The Boston Globe is reporting that authorities have an image of the suspect carrying and possibly dropping a black bag at the second bombing scene.
CNN's report remains unconfirmed. The FBI's national press office says "we have not officially named anyone and we don't know where they're getting that information." Boston Police also declined to comment to HuffPost Crime, saying they don't know about the possible suspect.
