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

She said Hackman died from hypertensive and atherosclerotic cardiovascular disease, with Alzheimer’s disease as a significant contributory factor. “The cause of death for Miss Betsy Hackman, aged 65 years, is hantavirus, pulmonary syndrome. The manner of death is natural,” Jarrell told reporters.
