The investigation into the deaths of Gene Hackman and Betsy Arakawa has uncovered new details. Following the discovery of the couple and one of their three dogs dead in their New Mexico home on Feb. 26, Santa Fe County Sheriff Adan Mendoza shared additional insights into key evidence.

According to an affidavit for a search warrant obtained by NBC News on Feb. 27, Arakawa, 65, was found on the bathroom floor near a space heater and an open bottle of prescription medication, with pills scattered across the countertop. The medications retrieved from the home included an unidentified thyroid medication, the pain reliever Tylenol, and the blood pressure drug Diltiazem, per the report as reported by E!News.

Investigators also seized a 2025 monthly planner, two green cell phones, and records from MyQuest—an online health lab results portal—as part of the warrant.

Earlier that day, Mendoza emphasized the importance of the medications in the ongoing inquiry, noting they were “a matter of concern.”

Sheriff Mendoza talked about the evidence on Today. He said, “That’s obviously very important evidence at the scene. That information was collected, that information was passed to the office of the medical investigator to help them make a determination. So we’re looking at that specifically and other medications that were possibly in the residence.”

Also, Mendoza mentioned a comprehensive report could take three months or longer to complete.

Yesterday it was discovered, Gene Hackman’s pacemaker was last active on Feb. 17, indicating the Oscar-winning actor may have been deceased for nine days before he and his wife, Betsy Arakawa, were found in their New Mexico home, the Santa Fe County Sheriff stated Friday afternoon.

“An initial interrogation was conducted of Mr Hackman’s pacemaker. This revealed that his last event was recorded on February 17, 2025, I was advised that a more thorough investigation will be completed,” said Mendoza. “I think that is a very good assumption that that was his last day of life,” Sheriff Adan Mendoza said according to Independent.

Leslie Anne Hackman, one of Gene Hackman’s three children, previously told DailyMail.com that she and her sister, Elizabeth Jean, suspected their parents may have died from inhaling toxic fumes due to a possible carbon monoxide leak.

However, after their bodies were discovered, Santa Fe City Fire personnel and the New Mexico Gas Company conducted tests for carbon monoxide and other hazardous substances in the home. Their investigation determined that the area was safe.
