There was no evidence of infectious disease, trauma or poisoning that could have resulted in death, according to a New Mexico Department of Agriculture report.

Gene Hackman, 95, died of cardiovascular and Alzheimer's disease likely around Feb. 18, about one week after his wife, officials said.

The deceased dog was found in the home with the bodies of the actor and his wife, Betsy Arakawa. The couple’s two other dogs had survived.
