The causes of deaths of actor Gene Hackman and his wife, Betsy Arakawa, were revealed by officials on Friday, more than one week after the couple was mysteriously found dead in their Santa Fe, New Mexico, home. Hackman, 95, died of cardiovascular and Alzheimer’s disease likely around Feb. 18, about one week after his wife died from a rare syndrome, hantavirus pulmonary syndrome, on about Feb. 11, officials said. Hackman’s death was from “hypertensive and atherosclerotic cardiovascular disease, with Alzheimer’s disease as a significant contributory factor,” Dr. Heather Jarrell, chief medical investigator for the state’s Office of the Medical Investigator, announced at a news conference.
