From Denver CBSLocal.com:
An Adams County man is in shock after he says deputies shot and killed his dog.
Jeff Fisher said deputies went to his house by mistake. He said when they forced their way through the door his dog Ziggy ran outside and an Adams County Sheriff’s deputy shot and killed him.
“(He went to the door) to see who it was and the police officer shot him three times,” Fisher said. “They killed my dog for no reason.”
