The New York Post has the latest:
Investigators probing the deadly Boston Marathon bombings are circulating photos of two men spotted chatting near the packed finish line, The Post has learned.
In the photos being distributed by law-enforcement officials among themselves, one of the men is carrying a blue duffel bag. The other is wearing a black backpack in the first photo, taken at 10:53 a.m., but it is not visible in the second, taken at 12:30 p.m.
These were the same two identified earlier by 4chan:
A federal law enforcement source told Fox News that investigators are looking for two men that are persons of interest in Monday's Boston Marathon terror attack and have distributed photos for “law enforcement eyes only.”
According to the reporter, one of the men has a backpack that appears to match the bag believed to have been used in the attack. The other man also appears to have a bag of some kind.
