On October 4th, a stray Beagle mix in an overcrowded animal shelter in Florence, Ala., was loaded into a gas chamber with 18 other dogs marked for death. 21-year-old Cody Berry, the worker assigned this awful task, locked the door, turned a key and pressed a button that releases carbon monoxide into the chamber. He returned later, The Star-Ledger reports, and heard something moving inside the chamber.
