Gene Hackman’s dog likely died of dehydration and starvation, showed partial mummification, report says

Gene Hackman and Betsy Arakawa Hackman's dog likely died from dehydration and starvation, according to a report obtained by The Associated Press.

The report, released by the Santa Fe County animal control agency, stated the partial mummification of the animal could have obscured changes in organs, but there was no evidence of poisoning, infectious disease or trauma that could have led to death.

The report also specified that the dog's stomach was empty, with only small amounts of hair and bile discovered. 

GENE HACKMAN DEATH: COMPLETE COVERAGE

Zinna, one of the couple's three dogs, was found when Hackman and Arakawa's bodies were discovered at their Santa Fe home Feb. 26. 

Authorities previously revealed that Zinna's body was discovered in a crate that was in a closet about "10 to 15" feet away from where Betsy's body was found on the floor of the bathroom. 

"There was a procedure that was done with the dog which may explain why the dog was in a crate," Santa Fe County Sheriff Adan Mendoza explained during the news conference.

The partial mummification of the animal could have obscured changes in organs, but there was no evidence of poisoning, infectious disease or trauma that could have led to death.

Zinfandel, who was called Zinna, was a mixed breed and was the couple's oldest dog. She was 12. 

The couple also owned two German shepherds — Bear, 4, and Nikita, 7.

During the investigation, officers discovered Betsy had picked up Zinna from Gruda Veterinary Hospital in Santa Fe Feb. 9. 

Gene died of hypertensive atherosclerosis cardiovascular disease, with Alzheimer's disease as a significant contributing factor, New Mexico officials confirmed one week ago.

The investigation remains ongoing until cellphone data can be reviewed.

Joey Padilla, the owner of Santa Fe Tails, had been working with Hackman and Arakawa, training and watching their dogs, for a decade. He previously told Fox News Digital the couple's pets were "attached" to Betsy.

"Anytime Betsy had an errand to do, they went with her. These dogs loved going on a ride in the car with Betsy, and it didn't matter if it was going to the store, even when we would go to dinner. We'd go to dinner, and the dogs would be in the car. They were very much attached to Betsy," Padilla explained.

"It's hard to explain and encompass how much these dogs meant to these people."

Padilla said Arakawa would never put her animals in harm's way.

"I want to reiterate there is nothing that Betsy wouldn't do for those three dogs. In my opinion, there is no way that dog was up on purpose or without a purpose. There was a reason. It just breaks my heart about Zinna. Zinna would not leave Betsy's side. They were attached to the hip. It was a pretty phenomenal connection," Padilla said.
