Local veterinarian Dr. Melinda Merck, one of the nation's top forensic vets, is assisting the prosecution in the investigation of dogfighting at property owned by Falcons quarterback Michael Vick in Surry County, Virginia, she confirmed Monday.

"I wasn't involved in that aspect," Merck said. "I have no direct knowledge of what they found and no one has called (Monday) to give me an update."

Merck said she couldn't comment on the specifics of her role in the investigation.
