Gene Hackman, his wife Betsy Arakawa, and their dog's mysterious deaths have authorities searching for answers ... and they’ve confirmed they're not ruling out carbon monoxide poisoning.

Santa Fe fire officials spoke on "TODAY" Friday, stating that while their meters didn’t detect anything amiss during searches, that doesn’t mean carbon monoxide poisoning is off the table -- especially since the bodies may have been there for days or even weeks.

They pointed out Gene and Betsy’s New Mexico home had natural gas ... and a leak could have dissipated by the time their bodies were discovered.

Gene Hackman seemingly had no health-related issues prior to his mysterious death ... this according to the late actor's daughter.

Speaking with the Daily Mail, Leslie Anne Hackman says, "there was no indication that there was any problem," leading up to his tragic death. She also notes Gene did not recently undergo any significant surgeries.

While Gene was 95 years old, his daughter claims he was in very good physical condition, participating in activities like Pilates and yoga several times a week -- with his wife, Betsy Arakawa, playing an imperative role in his healthy lifestyle. As we reported, a close friend of Gene's tells us Betsy made sure GH stuck to a strict diet.

Gene Hackman's death and the deaths of his wife and dog are puzzling authorities, who have labeled his passing "suspicious."

According to a search warrant, obtained by TMZ, a Santa Fe detective who sought a search warrant wrote in his affidavit, he believes "the death of the two deceased individuals to be suspicious enough in nature to require a thorough search and investigation because the reporting party found the front door of the residence unsecured and opened."

The detective continues, "Deputies observed a healthy dog running loose on the property, another healthy dog near the deceased female, a deceased dog laying 10-15 feet from the deceased female in a closet of the bathroom, the heater being moved, the pill bottle being opened and pills scattered next to the female, the male decedent being located in a separate room of the residence, and no obvious signs of a gas leak."
