CHANDLER, AZ (3TV/CBS 5) – It’s almost unbelievable, and Conrad Calderon is in shock. He said someone stabbed and killed his pet, Tawny, right in front of him. Calderon has spent the last few days putting up flyers, calling the person responsible a “loose cannon.” He’s hopeful to find witnesses and video evidence to help bring justice for Tawny. “Who stabs a dog that doesn’t even bite your dog?” said Calderon. “There’s an animal out there. I hate to call him an animal. This seems subhuman, sub animal.”
