FEDS: No arrest yet in Boston Marathon bombing [UPDATED]Published 1:22pm Wednesday, April 17, 2013 Updated 2:42pm Wednesday, April 17, 2013
Investigators scrambling to solve the fatal bombing at the Boston Marathon have made “significant progress” in the case but no arrests, a federal law enforcement source told CNN’s John King Wednesday.
The FBI also officially confirmed in a statement that no arrests had been made.
The denials came after sources previously told CNN that a suspect was in custody.
One federal law enforcement source told CNN that “anyone who says ‘arrest’ is ahead of themselves.”
A Boston law enforcement told CNN, “We got him,” but won’t clarify whether that means a suspect has been identified or arrested.
Some federal sources said it was even too early to say investigators had identified the suspect, but several sources in Boston told CNN that they have a clear identification.
The back-and-forth developments came after a chaotic day in which investigators revealed more details about the makeup of the bombs and apparently unrelated scares over letters containing ricin gripped the nation’s capital.
The bombs exploded 12 seconds apart near the finish line of the Boston Marathon, killing three people and wounding about 180 others.
One of the bombs was housed in a pressure cooker hidden inside a backpack, the FBI said in a joint intelligence bulletin. The device also had fragments that may have included nails, BBs and ball bearings, the agency said.
The second bomb was also housed in a metal container, but it was not clear whether it too was in a pressure cooker, the FBI said.
The U.S. government has warned federal agencies in the past that terrorists could turn pressure cookers into bombs by packing them with explosives and shrapnel and detonating them with blasting caps.
