YELM, Wash. (KOMO) -- The Thurston County Sheriff's Office is investigating the shooting death of a pet dog owned by actress Salma Hayek. 
 
 Hayek announced on Instagram that she was mourning the death of her pet dog, found shot dead on her ranch near Yelm on February 19. 
 
 "I haven't posted for a week as I been mourning the death of my dog, Mozart who I personally delivered out of his mother's womb," the 49-year-old actress wrote. 
 
 According to Lt. Cliff Ziesemer with the Sheriff's Office, groundskeeper Jody Littlejohn was on horseback when she took Hayek's two dogs out for run that day. Mozart ran off, which Littlejohn said isn't unusual on a ranch that size. 
 
 It is unclear whether Mozart ran onto someone else's property, but Ziesemer believes the dog may have, and was shot with a pellet gun by the property owner. 
 
 A .177 caliber bullet nicked an artery, and as Mozart ran back onto Hayek's property, the dog collapsed and died. He was found by Littlejohn who went to look for him. 
 
 Ziesemer called the fatal shot "a fluke" that wouldn't have normally killed a dog. He believes whomever fired the pellet gun was most likely just trying to scare Mozart away. 
 
 Hayek was in Los Angeles at the time of the shooting, but Mozart lived on the ranch full time, Ziesemer said. 
 
 Investigators are going back Sunday in hopes of finding the shooter. 
 
 No charges are expected to be filed unless something drastic changes, Ziesemer said. ||||| Salma Hayek Cops Say Neighbor Had Right to Shoot Dog 
 
 Salma Hayek: Cops Say Neighbor Had Right to Shoot Dog 
 
 EXCLUSIVE 
 
 Salma Hayek's beloved dog was shot and killed by a neighbor, TMZ has learned, and cops have closed the case because the dog was trespassing on his property. 
 
 As we reported, Salma's 9-year-old dog, Mozart, was found dead last week at her Washington state ranch. 
 
 Cops launched an investigation and tell us Salma's neighbor confessed to shooting the dog, but there were extenuating circumstances. The neighbor told police he was sick of her dogs coming onto his property and attacking his dogs, which he says happened every time Salma's caretaker took the pets for a walk. 
 
 The neighbor told cops... several of Salma's dogs were in his garage on the day in question ... and he used a pellet gun to scare the animals away. The neighbor said he had no intention of killing any of the animals and cops also believe the pellet gun ordinarily would not be lethal. 
 
 Police have closed the investigation since the dogs were on the neighbors property. ||||| by: KIRO 7 Staff and The Associated Press Updated: Feb 28, 2016 - 5:16 PM

 Actress Salma Hayek says her pet dog, Mozart, was shot to death at her ranch last week, located in Washington state. 
 
 The 9-year-old dog was shot close to his heart, Hayek says. The Thurston County Sheriff’s Office is investigating. 
 
 Deputy Lt. Cliff Ziesemer says a caretaker was riding a horse around Hayek's property with two dogs following. He says the dogs barked and took off running at the end of the road but eventually came back, as was typical. 
 
 Later, when the caretaker returned home she realized one dog was missing. She found the dog dead and reported it to authorities. 
 
 “I am hoping that the Washington State authorities do justice to this wonderful dog whom in 9 years never bit or attacked anyone,” she writes in her post. 
 
 Ziesemer says a veterinarian determined a pellet from a pellet gun had nicked an artery and that the dog "slowly bled to death internally." 
 
 An autopsy showed that a pellet gun shot through two ribs and nicked an artery. It is not clear where on the property the dog was shot. 
 
 Salma says that she personally delivered the dog from his mother’s womb. 
 
 “... he was the most loving and loyal companion,” she writes. “He didn’t deserve a slow and painful death.” 
 
 Hayek is a self-proclaimed animal lover, saying in a 2013 interview with "The Ellen DeGeneres Show" that she had five horses, four alpacas, one cat, eight dogs, one hamster, five parrots, two fish, 20 chickens and multiple rabbits and turkeys. 
 
 In August last year, Hayek told Jimmy Fallon that she had nine dogs. 
 
 The Sheriff’s Office says they will have more information later this week. 
 

– Salma Hayek had hoped cops would track down the person who shot and killed her dog in mid-February at her ranch in Washington state, and they did—but it looks like there won't be any charges. A neighbor of Hayek's has confessed to shooting 9-year-old Mozart with a pellet gun, per TMZ, but police have already closed the case because the neighbor says he shot the pellet gun just to scare Hayek's dogs off his property. He says her dogs are a constant nuisance on his land and that they attack his own dogs. An officer with the Thurston County Sheriff's Office tells WJLA that the fatal pellet-gun shot was a "fluke" that normally wouldn't kill a dog. An autopsy showed that the bullet cut into one of Mozart's arteries and that he "slowly bled to death internally," he says, per KIRO 7. (A veteran demanded a military burial for his service dog, who was shot and killed by a cyclist.)
