The lead investigator in the case of Madeleine McCann, a British toddler who disappeared in 2007, says two different people came up with the same name in response to a computer-generated sketch of a man they want to question.
The man was seen by witnesses carrying a child matching Madeleine McCann's description on the night she vanished.
McCann went missing just a few days before her fourth birthday during a family vacation in Portugal.
OutFront: John Walsh. He profiled McCann's case several times on America's Most Wanted and has met with Madeleine McCann's parents.
