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.

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.
