Humane agents responding to a report of two dogs living in unsanitary conditions in the Feltonville section of Philadelphia found the live dogs and the remains of dozens of animals believed to have been sacrificed in a religious ritual.

George Bengal, the Pennsylvania SPCA's chief of law enforcement, said agents found a house "covered in feathers" and a blood-splattered altar. The skeletal remains are believed to be of dogs, cats, farm animals and possibly primates, he said. More from Inquirer and Daily News.
