(Yelm, WA)  --  The Thurston County, Washington Sheriff's Office says a man who shot and killed a dog belonging to actress Salma Hayek may have been justified.  Authorities say the man claimed the German shepherd wandered last week onto his property and attacked his pets.  Hayek, who runs an animal sanctuary on her ranch in Yelm, says the dog, named Mozart, never bit or attacked anyone.  Thurston County Sheriff John Snaza says it appears the homeowner was only protecting his animals and not trying to purposefully kill or maim a dog.
