Gene Hackman Died a Week After His Wife, Both From Natural Causes

The actor Gene Hackman died from heart disease at his home in New Mexico, most likely a week after his wife, Betsy Arakawa, died from the effects of hantavirus, a disease linked to rodents that can cause respiratory failure in rare cases, the authorities said on Friday.

The revelation that the famous and reclusive couple had died of natural causes put to rest much of the speculation that followed the discovery of their bodies on Feb. 26. But it also raised new questions about the state of mind of Mr. Hackman, who investigators said had advanced Alzheimer’s disease, and why the couple was not discovered sooner.

Ms. Arakawa, 65, had run a series of errands on Feb. 11, but the authorities could find no evidence of any activity after that, suggesting that she could have died that day. Mr. Hackman, 95, is believed to have died about a week later, on Feb. 18, according to New Mexico’s chief medical examiner, Dr. Heather Jarrell.

Mr. Hackman was found on the floor of the mudroom in the couple’s home, near his cane, while Ms. Arakawa was found on a bathroom floor, beside a counter with common medication scattered about that investigators later determined did not play a role in her death. They were not discovered until Feb. 26, when a maintenance worker arrived to the couple’s home east of Santa Fe and grew worried when no one answered the door. The worker contacted a security guard, who called 911.

Dr. Jarrell said it was possible, given Mr. Hackman’s Alzheimer’s disease, that he did not know that his wife had died. It was unclear whether Mr. Hackman was able to take care of himself on his own. Autopsies were performed on the couple, Dr. Jarrell said, and Mr. Hackman’s showed that his stomach was empty, meaning he had not eaten recently, but she said he did not appear to be dehydrated.

Sheriff Adan Mendoza of Santa Fe County said investigators did not find any evidence that Mr. Hackman had communicated with anyone after his wife’s death.
