Federal investigators are searching the Surry County, Virginia property of Falcons quarterback Michael Vick for second time in a month. As many as 15 vehicles with government license plates are at Vick's property and agents are digging under at least one blue tarp in an on-going dog fighting and animal cruelty investigation. Also on the scene is a U-Haul truck and state police. A U.S. Department of Agriculture agent stationed at the front gate of the property would not comment to a reporter. All questions were referred to James Rybicki, of the United States Attorney's Office. "We've seen the same reports that agents are on the property, but for the record we don't have any comment," said Rybicki, public information officer for the United States Attorney's office, Eastern District of Virginia.
