Here are some key dates and developments in the investigation leading to dogfighting indictments against Atlanta Falcons quarterback Michael Vick and three others:

April 24: Michael Vick's cousin Davon Boddie is arrested in Hampton on drug charges. According to court papers, he gives his address as 1915 Moonlight Road in rural Surry, and police obtain a warrant to search his home for other drugs and paraphernalia.

April 25: Police serve the warrant in Surry and find numerous dogs and what looks like a dog-training complex of dark-painted buildings in the woods just behind the house owned by Vick. They call animal-control officers, who count 66 dogs and see what they say is evidence that dogfights had taken place there. Police obtain another warrant and seize the dogs and various items.

May 23: Investigators obtain a third warrant, this one to search the property for buried dog carcasses. But the local prosecutor decides not to execute it, saying he is worried the dogfighting warrants are tainted because the animal-control officers might have been overzealous in their searches.

June 7: More than a dozen representatives of the U.S. Attorney's Office in Richmond, U.S. Department of Agriculture and Virginia State Police converge on the Moonlight Road property, apparently executing a sealed federal search warrant.

July 2: Authorities allege in court documents that a dogfighting venture called Bad Newz Kennels had operated at the Vick property for the past five years. The U.S. attorney's office files papers seeking federal government ownership of about 53 pit bulls that were among the dogs seized from Vick's property.

July 6: Federal authorities conduct another search of the Vick property, apparently again seeking evidence of dogfighting in the form of animal remains.

July 17: The U.S. Attorney's Office in Richmond announces that Vick and three others have been indicted by a federal grand jury in connection with dogfighting.
