An examination of the dog found dead along with actor Gene Hackman and his wife in their Santa Fe home shows dehydration and starvation were likely what led to the animal's demise.

Gene Hackman and his wife Betsy's wills have been revealed publicly. The couple had named each other as the personal representatives and recipients of their estates before they were both found dead in their home on Feb.

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