Police update on Gene Hackman's cause of death after testing his pacemaker
The two-time Oscar winner and his wife Betsy Arakawa were found dead, along with one of their dogs, at their home in Santa Fe, New Mexico, on Wednesday
Forensic tests on the pacemaker of Gene Hackman have revealed that the actor, aged 95, was still alive as recently as February 17, due to a "last event" logged nine days prior to the discovery of both his and his wife Betsy Arakawa's bodies in their Santa Fe residence.
The two-time Academy Award winner and his spouse, aged 65, were found deceased alongside one of their pets this Wednesday with no clear indications of foul play according to the police.
Authorities consider it a plausible conclusion that Hackman's demise occurred concurrent with his pacemaker's final recorded event. During a press briefing, Santa Fe County Sheriff Adan Mendoza—who had earlier consulted with a pathologist engaged in the case—conveyed, "Both individuals tested negative for carbon monoxide."

He shared updates on the investigation, stating: "An initial interrogation was conducted of Mr Hackman's pacemaker. This revealed that his last event was recorded February 17 2025, I was advised that a more thorough investigation will be completed. Initial findings noted no external trauma to either individual. The manner and cause of death has not been determined. The official results of the autopsy and toxicology reports are pending."
There had been some confusion about the security of the Hackman home, as Mendoza addressed previously conflicting reports about which doors were locked. He clarified that several doors were actually unlocked with a back door open, permitting two surviving dogs to move freely in and out.
The Sheriff mentioned his belief that the front door was shut but not locked. Two additional canines were found unharmed at the property, with one inside and one outside.
The alarm was raised by a maintenance worker conducting pest control at the property, who grew concerned after not seeing the couple for some time, according to police. Following the discovery of the bodies, New Mexico Gas Company tested the gas lines in and around the home, as per a search warrant, but found no issues.
Police are still trying to establish the couple's last known contact with others, a task made difficult due to their private lifestyle, stated Mr Mendoza. After the bodies were found, a search was conducted and several items were "secured from the residence for evidentiary purposes". These included two green mobile phones, two bottles of medication, medical records, and a 2025 monthly planner.

Efforts are now underway to examine the cell phones and scrutinise a calendar found near the couple's bodies. Contact will also be made with workers, security staff, and family members. Mr Mendoza noted that there is no evidence to suggest the couple fell, stating: "I don't think, you know, there was any indication that, again, there was no trauma or injured themselves, or head injury or brain injury."
Dr Philip Keen, the retired chief medical examiner in Maricopa County, Arizona, explained that while the moment a pacemaker stops working could indicate the time of death, it's not always the case. He added: "If your heart required a pacemaker, there would certainly be an interruption at that point – and it might be the hallmark of when the death occurred. But it's not necessarily because some people get a pacemaker to augment things, not necessarily replace things."
He also expressed doubt about the likelihood of someone initially testing negative for carbon monoxide to later be diagnosed with poisoning from it.
