NEW YORK -- A New York man admitted in a plea deal on Thursday he posed as a firefighter at ground zero the day after the Sept. 11 attack and stole expensive watches and gems from a World Trade Center store. Johnny Dunham, 26, of the Bronx, faces up to seven years in state prison when he is sentenced on March 21 by Manhattan supreme court judge Herbert Altman. Dunham, who had been arrested previously for impersonating police officers, admitted to stealing as many as 20 Tourneau and Cartier watches and $2,500 cash from Tourneau's watch store that was on the first sub-level of 5 World Trade Center. Tourneau officials had told police that the wholesale value of the missing merchandise was $1.3 million, Reuters reported.
