U.S. attorney Charles “Charlie” Peeler of the Middle District of Georgia will be using the federal Animal Welfare Act to prosecute alleged drug traffickers he says have been running a “barbaric” business.

Together with local law enforcement agencies and the Georgia Bureau of Investigation, Peeler executed 11 search warrants Wednesday at different locations around the region as part of a months long investigation, he announced. And that’s how the U.S. Marshals Service came to be in possession of roughly 160 rescued dogs.
