Clues Sought in Burning of Bag Holding 5 Dogs Animal protection authorities are looking for the people who set fire to a bag containing five pit bulls behind a beverage distribution warehouse in East Flatbush, Brooklyn, on Saturday. The dogs, four puppies and one adult dog, are all dead, said Bret Hopman, a spokesman for the American Society for the Prevention of Cruelty to Animals. "It is unclear whether the dogs were dead or alive prior to being place in the bag," he added. He said necropsy results expected by the end of the week should answer that question. The bag was found by workers at the warehouse, at East 91st Street and Ditmas Avenue, on Monday, and they examined security footage and found images of men getting out of a van with a bag and setting it aflame, Mr. Hopman said. Sammy Omar, a worker at the warehouse, told WNBC-TV: "We seen the dog outside all burnt up, the babies all burnt up. It was horrible. Grainy footage shown on WNBC (see video below) shows two men with backs to the camera, one carrying a plastic garbage bag, walking toward a trash pile, and then a bag burning.
