BOSTON (AP) — Investigators poring over photos and video from the Boston Marathon bombing have a department-store surveillance-camera image of a man dropping off a bag at the scene of the one of the blasts, a top city politician said Wednesday.

City Council President Stephen Murphy, who said he was briefed by members of the Boston Police Department, said he does not know if investigators know the man’s name. He said officers are chasing leads that could take them to the suspect.
