But NBC News, citing its own sources, say only that investigators are "zeroing in on some people." But the network's Pete Williams cast doubt on the claim that a suspect has been identified, saying that reports are "simply not correct."

The Boston Globe and Reuters have also reported that investigators have a suspect.
