Earlier today, CNN's John King reported that authorities had identified a suspect based on an analysis of video from a Lord & Taylor department store near the site of the second blast, and that video from a Boston TV station also helped. King cited a source who was briefed on the investigation.
A federal law enforcement source told CNN's Fran Townsend that someone was arrested. But two senior administration officials and another federal official then told Townsend that there had been a misunderstanding among officials and that no one has been arrested.
Scores of victims of the Boston bombing remained in hospitals, many with grievous injuries. Doctors who treated the wounded corroborated reports that the bombs were packed with shrapnel intended to cause mayhem. In addition to the 5-year-old child, a 9-year-old girl and 10-year-old boy were among 17 victims listed in critical condition. (ESPN Boston)"
