RICHMOND, Va. - Atlanta Falcons quarterback Michael Vick will plead guilty to federal dogfighting conspiracy charges after prosecutors presented new evidence uncovered by McGruff the Crime Dog. "He sniffed out clues that we missed," said Sheriff Andy Taylor, "and he worked, well, doggedly on this until Vick had no choice but to plead guilty." These developments triggered a heated exchange between Vick and McGruff outside the offices of Vick's lead defense attorney Billy Martin. Vick told McGruff, "You're a son of a bitch." McGruff replied, "Well, that's one thing you got right."
