Autopsies have been completed on Gene Hackman and his wife, Betsy Arakawa, after their unexplained deaths in their $3.8 million Sante Fe home. Authorities found “no external trauma to either individual,” according to Sheriff Adan Mendoza.

Despite speculation, carbon monoxide poisoning was ruled out. The Santa Fe City Fire Department and New Mexico Gas Company tested the home, confirming it was safe. An affidavit stated, “New Mexico Gas Company responded to the residence and was testing the gas line in and around the residence.”

Hackman’s daughter, Leslie Anne, suggested toxic fumes could have been the cause. However, investigators found “no indications or proof that the pipes in and around the house have ever had any issues.”

Authorities are waiting for toxicology reports for further insights into the cause of death.

The investigation continues as family and fans seek answers regarding the couple’s tragic passing.
