"Authorities circulate photos of two men spotted carrying bags near site of Boston bombings," by Larry Celona, Brad Hamilton and Jamie Schram for the New York Post, April 18 (thanks to Andrew Bostom):

Cops are seeking these two men (above) who were spotted near the site of the Boston blasts. 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.
“The attached photos are being circulated in an attempt to identify the individuals highlighted therein,” said an e-mail obtained by The Post. “Feel free to pass this around to any of your fellow agents elsewhere.”
Meanwhile, officials have identified two potential suspects who were captured on surveillance videos taken shortly before the deadly blasts, law-enforcement sources told The Post yesterday.
