CNN — Investigators believe they have identified a suspect in the Boston Marathon bombings, a source who has been briefed on the investigation told CNN's John King. The possible breakthrough came from an analysis of video from a Lord and Taylor department store near the site of the second blast, and video from a Boston TV station helped as well, the official said. Authorities have a clear image of someone placing the kind of package authorities are looking for, including clear identification of the possible suspect's face, the source told King.
