But it turns out that the man they paraded before the cameras wasn't Guzman's son after all; instead, it was a used-car salesman named Felix Beltran Leon, reports the BBC. Now Mexico is blaming the US for the bad information, and the US is blaming Mexico, notes AP. As for the 23-year-old car salesman, he remains in custody because authorities say they found guns and cash when they raided his house. His lawyer, though, says that cops planted the guns and that the cash can be explained by the recent sale of a house. "He's never been arrested," insists his mother. "This is a real injustice."
