4 FEBRUARY 2009 Seeing William Petersen dusting a pavement for clues isn't too surprising - after all he is the Las Vegas crime lab's top forensic specialist.
No crime had been committed, however. The CSI: Crime Scene Investigation actor was, in fact, playing to the cameras as he accepted a star on the Hollywood Walk Of Fame.
Saying he was "overwhelmed" by the honour, William added: "I never expected it".
Marg Helgenberger, who plays his number two in the TV show, paid an emotional tribute to her co-star. "Millions of fans love him for his many memorable roles. Yet the sum of all the parts he's played don't come close to the complexity, the kindness, the mystery, the loyalty and the generosity that is Billy himself," she said.
