Boston Marathon investigation: FBI may have suspect, CNN reports

BOSTON (CNN/Yahoo) - Authorities may have identified a suspect in the Boston Marathon bombings, CNN reports.

The FBI is holding a press conference at 5:00 p.m. and may announce the news then. CNN attributed the news to an unnamed source, and reported that the breakthrough in the investigation came from analyzing department store surveillance video and video from a news station.

The Boston Globe reported that officials have found an image of "a suspect carrying, and perhaps dropping, a black bag at the second bombing scene."

An FBI spokesman in Boston declined to comment on the reports to Yahoo News.
