Gene Hackman died due to hypertensive atherosclerosis cardiovascular disease, with Alzheimers as a significant contributing factor, New Mexico officials confirmed Friday. He was likely alone in the home for about a week, until he died around February 18th, which was the last time activity was recorded on his pacemaker.
His wife, Betsy (Arakawa) Hackman, died due to Hantavirus Pulmonary Syndrome, which is transmitted from animals to humans and is commonly found in rodents, the New Mexico Department of Health confirmed. Betsy’s autopsy determined the manner of death as natural. Authorities believe Betsy died on about Feb. 11.
Chief Medical Investigator Dr. Heather Jarrell performed a full autopsy on Hackman the day after his body was discovered, which showed “severe heart disease, including multiple surgical procedures involving the heart, evidence of prior heart attacks, and severe changes of the kidneys due to chronic high blood pressure.”

She added, “Examination of the brain showed advanced Alzheimer’s disease as well as blood vessel changes in the brain secondary to chronic high blood pressure.”
Jarrell noted that Hackman’s pacemaker data indicated “abnormal rhythm of atrial fibrillation” on Feb. 18. She said it was “reasonable to conclude” Arakawa died the week before Hackman, with the actor’s death likely on Feb. 18.
“Based on the circumstances, it is reasonable to conclude that Miss Hackman passed away first, with February 11th being the last time that she was known to be alive,” Jarrell said.
Gene and Betsy, who were married for more than 30 years, and one of their dogs, were found dead in their Santa Fe home on Feb. 26 by maintenance workers.

Detectives initially described their deaths as “suspicious enough in nature to require a thorough search and investigation,” according to a search warrant affidavit obtained by Fox News Digital.
Officials confirmed that no external trauma was seen on either Gene or Betsy, and New Mexico authorities promptly launched a criminal investigation into their deaths. The case remains open pending autopsy and toxicology results.
Gene and Betsy previously tested negative for carbon monoxide, Mendoza confirmed last week. Their residence was tested for the colorless, odorless gas and was cleared by the Santa Fe City Fire Department after authorities were unable to find evidence of a carbon monoxide leak or poisoning.

Additionally, the New Mexico Gas Company confirmed Tuesday “no significant findings” after conducting an extensive investigation for gas leaks and carbon monoxide at the couple’s secluded home.
A “minuscule leak (0.33% gas in air – not a lethal amount) at one of the stove burners” was discovered, according to a release obtained by Fox News Digital. Four code enforcement violations were also noted involving “a water heater and gas log lighters installed in three fireplaces.”

Mendoza previously said the last week that the last recorded activity on Gene’s pacemaker occurred on Feb. 17. Authorities assumed this was Gene’s last day alive, as the Oscar winner’s body was not discovered for nine more days.
“According to the pathologist, I think that is a very good assumption that that was his last day of life,” Mendoza said.
