On July 7, federal authorities conducted a second search of the Surry, Va., property owned by Vick that is the center of the dogfighting investigation.
According to court documents filed by federal authorities earlier after that search, dogfights have been sponsored by "Bad Newz Kennels" at the property since at least 2002.
Fifty-four pit bulls were recovered from the property during searches in April, along with a "rape stand," used to hold dogs in place for mating; an electric treadmill modified for dogs; and a bloodied piece of carpeting, the documents said.
During a June search of the property, investigators uncovered the graves of seven pit bulls they allege were killed by members of Bad Newz Kennels after testing sessions.
