A San Bernardino County Sheriff's Department deputy fatally shot a dog while responding to a report of a stolen vehicle on Monday morning, "Having to go to my security cameras, and seeing what they did, it was just horrifying," Homeowner Jesus Serna told CBS LA Wednesday when recounting the shooting of his dog, a Rottweiler named Daisy. Serna is now asking for police to investigate why the deputy went into his backyard, which was found to be unconnected to the stolen vehicle, and opened fire on his dog.
