An investigation into the death of Salma Hayek's dog at her Washington ranch has reportedly been closed by authorities.

When the actress' neighbor shot her 9-year-old pet, Mozart, the dog was allegedly trespassing on the neighbor's private property -- something the neighbor told police happened whenever Salma's caretaker walked the pooches, who purportedly had a habit of attacking the neighbor's dogs, according to TMZ.

The neighbor reportedly said he used a pellet gun to scare the animals off after spotting them in his garage; he said he had no intention of killing any of them.

Police tell TMZ the neighbor had a right to shoot the dog since it was on his property.

Mozart was discovered back on Salma's turf after the shooting. In a distraught post on Instagram, the actress said the dog bled to death from the pellet injury.

"I am hoping that the Washington State authorities do justice to this wonderful dog whom in 9 years never bit or attacked anyone," she wrote. "He loved his territory and never strayed away...he was the most loving and loyal companion. He didn't deserve a slow and painful death."

The devoted pet owner told Ellen DeGeneres in 2013 that her brood included "five horses, four alpacas, one cat, eight dogs, one hamster, five parrots, two fish," some turkeys, about 20 chickens and 20 rabbits.
