BOSTON — Investigators were zeroing in Wednesday on video footage from a department store security camera, possibly showing a man wearing a large backpack and then dropping it, in the first sign of a possible breakthrough in the investigation of the Boston Marathon bombings.
A Boston city official told The Washington Post that the Lord & Taylor camera on Boylston Street, directly across from the site of the blasts, is of “special interest” to investigators. CNN reported that authorities have used the footage and other footage to identify a possible suspect
