One of Michael Vick's co-defendants pleaded guilty Monday to his role in a dogfighting conspiracy he says was financed almost entirely by the Atlanta Falcons quarterback. As part of a plea agreement, Tony Taylor pledged to fully cooperate with the government in its prosecution of Vick and two other men accused of running an interstate dogfighting enterprise known as "Bad Newz Kennels" on Vick's property in rural Surry County. "The 'Bad Newz Kennels' operation and gambling monies were almost exclusively funded by Vick," a summary of facts supporting the plea agreement and signed by Taylor states.
