RALEIGH -- A Cary family is grieving the loss of its Chihuahua, and the next-door neighbor stands accused in the slaying. On Monday, Cary police arrested Ivo Strahilov Dernev, 35, of 209 Dundalk Way in connection with the shooting death of Charlie, a 4-year-old dog belonging to Shannon Young. Charlie died Sunday after a pellet from a .177-caliber Crossman Air Rifle blocked a major artery and caused massive internal bleeding, according to Young and Dernev's arrest warrant. "We've lost a lot," Young said about Charlie's death. "I can't replace him."
