Gene Hackman Cause of Death: Autopsy Heart Disease, Alzheimer’s

Gene Hackman spent decades becoming one of Hollywood’s most decorated actors, winning two Oscars and starring in classics from “The French Connection” to “Unforgiven.” At 95, the legendary actor was found dead alongside his wife and their dog in their Santa Fe home in February 2025. What investigators discovered in the weeks that followed paints a picture of a man whose body had been failing quietly for some time.

Age at Death: 95 · Approximate Death Date: February 18, 2025 · Primary Cause: Severe heart disease · Contributing Factor: Advanced Alzheimer’s · Wife’s Cause: Hantavirus pulmonary syndrome

The key facts below summarize the essential details surrounding Gene Hackman’s death and the circumstances that led to it.

What was the toxicology report on Gene Hackman?

The New Mexico Office of the Medical Investigator released its full autopsy findings in April 2025, roughly two months after Hackman and his wife were discovered. According to 6ABC News, the two-time Oscar winner died from severe heart disease, with advanced Alzheimer’s listed as a contributing factor.

Autopsy confirmation details

The autopsy painted a detailed picture of Hackman’s cardiac history. He had received a bi-ventricular pacemaker in April 2019, had an aortic valve replacement, and documented coronary artery stents and bypass grafts. His heart showed evidence of congestive heart failure, an irregular heartbeat, and remote myocardial infarctions in the left ventricular free wall and septum.

Brain examination confirmed what his family had long suspected: microscopic findings showed advanced stage Alzheimer’s disease. However, his toxicology screen came back clean—he tested negative for hantavirus, alcohol, and intoxicating drugs. Carbon monoxide saturation was less than 5%, well within normal range.

Heart disease and Alzheimer’s factors

One finding stood out to investigators: elevated acetone levels of 5.3 mg/dL, compared to normal endogenous levels of up to 0.3 mg/dL. According to Fox News, this indicated prolonged fasting that likely contributed to metabolic stress on an already compromised cardiovascular system.

The combination proved fatal. His pacemaker recorded abnormal heart rhythm on February 18, the day he likely died. For a 95-year-old with his cardiac history, the week without his wife—his primary caregiver—appears to have accelerated his decline.

What is Gene Hackman’s wife cause of death?

Betsy Arakawa, 66, died approximately one week before her husband. According to 6ABC News, she succumbed to hantavirus pulmonary syndrome on February 11, 2025—a rare rodent-borne disease that was entirely unrelated to Hackman’s cardiac condition.

Hantavirus pulmonary syndrome

The New Mexico Office of the Medical Investigator confirmed the diagnosis during an April news conference led by Chief Medical Investigator Dr. Heather Jarrell. Hantavirus is transmitted from animals to humans and is commonly found in rodents, according to Fox News.

The disease begins with flu-like symptoms including fever, muscle aches, cough, and sometimes vomiting and diarrhea—making early diagnosis difficult. As the condition progresses, patients develop shortness of breath that can quickly escalate to cardiac or respiratory failure.

Rodent-borne disease link

Investigators found evidence of rodent nests near the couple’s Santa Fe property, consistent with hantavirus exposure. What makes Arakawa’s case particularly poignant is that she had been researching symptoms in the days before her death. According to Fox News, she researched COVID-19 and flu-like symptoms at least four times between February 8 and 11, and sent an email to a massage therapist on February 11 mentioning that Hackman had taken a COVID test after experiencing flu or cold-like symptoms.

She also sought medical attention at Cloudberry Health center in Santa Fe before her death, likely in an attempt to address whatever was ailing her.

Was Gene Hackman’s dog found dead?

When authorities discovered Gene Hackman and Betsy Arakawa in their Santa Fe home on February 18, 2025, they found a third body nearby: the family dog. All three—actor, wife, and pet—were deceased in the residence.

Reports from Santa Fe discovery

The discovery was made after a welfare check was requested, though the identity of who called authorities remains unconfirmed in public records. Santa Fe police and emergency responders found all three deceased inside the home.

Connection to family deaths

The dog’s cause of death has not been publicly released as part of the autopsy documentation. What is clear is that the animal was found in proximity to both Hackman and Arakawa, suggesting it died around the same time. The rodent infestation noted near the property raises questions about whether the dog may have had exposure to the same environmental factors affecting the household.

How did Gene Hackman not know his wife died?

The question assumes a level of awareness that Hackman no longer possessed. His advanced Alzheimer’s diagnosis means he likely never understood that his wife had passed away.

Advanced Alzheimer’s impact

Brain examination confirmed advanced-stage Alzheimer’s disease. At this severity, patients typically experience significant cognitive decline that would prevent them from recognizing a spouse’s absence or understanding changes in their environment.

Inability to care for self

Without his wife’s daily care, Hackman’s condition deteriorated rapidly. The elevated acetone levels suggesting prolonged fasting indicate he was unable to feed himself in the days after her death. His pacemaker data showing abnormal heart rhythm on February 18 suggests his cardiovascular system was already in distress before his death that same day.

Seven days passed between Arakawa’s death on February 11 and Hackman’s on February 18. For a 95-year-old with severe cardiac disease and advanced dementia, the absence of a caregiver proved fatal within a week.

What is Gene Hackman’s daughter saying about his death?

Gene Hackman had three children from his first marriage: sons Erin and Scott Hackman, and daughter Leslie Hackman. Following the autopsy release in April 2025, family members provided public statements through representatives.

Family statements post-autopsy

The family requested privacy as they processed the detailed findings. Their response to the autopsy results has been measured, focusing on honoring both Hackman and Arakawa’s memory rather than contesting the medical findings. For more information, you can read Adriana Valle’s death.

Funeral attendance

Hackman’s children attended funeral services held in Santa Fe following the discovery. Both bodies were subsequently cremated. Leslie Hackman and her brothers have maintained a relatively private stance, releasing limited public comments about their father’s legacy and passing.

Timeline of events

The investigation into Gene Hackman and Betsy Arakawa’s deaths unfolded over roughly ten weeks, with key revelations coming in February 2025.

The timing reveals the tragic sequence: a wife trying to research her symptoms, a husband too cognitively impaired to understand the household was in crisis, and a seven-day window where neither could summon help.

Confirmed facts and open questions

Medical investigators established clear findings for both deaths, though some questions remain unanswered.

Summary

The autopsy findings end weeks of speculation but confirm what many suspected: Gene Hackman’s death was the inevitable result of a body that had been failing for years, complicated by advanced Alzheimer’s and compounded by the loss of his caregiver. For his wife Betsy Arakawa, hantavirus—a rare, rodent-borne disease with flu-like early symptoms—progressed too quickly for medical intervention to matter.

The discovery of their dog adds a final layer of tragedy to a story that began with a welfare check and ended with a family cremating their loved ones weeks later. For those wondering about the circumstances of two celebrated lives ending in such rapid succession, the answer lies not in foul play or mystery but in the quiet cruelty of disease and time.
