Investigators probing the Boston Marathon bombings are circulating photos of two men spotted near the finish line in an attempt to ID the possible suspects.
One of the men was carrying a blue duffel bag. The other was wearing a black backpack in a photo taken at 10:53 a.m. In a second photo at 12:30 p.m., he was not.
At this time, there is no official named Boston Marathon bombing suspect, nor has there been an arrest, as erroneously reported Wednesday afternoon.
However, authorities are clearly in hot pursuit.
An inter-agency manhunt led by the FBI, Boston PD and Massachusetts State Police - and maybe even aided by Reddit and 4Chan - produced the photos.
