Gene Hackman’s family suspect the 95-year-old died of carbon monoxide poisoning, the actor’s daughter has said.
Elizabeth Jean Hackman told TMZ the family thinks “the cause (of death) might be from toxic fumes”.
However, the publication did state that Hackman’s daughter claimed she and family members remained “unsure”.
Santa Fe County Sheriff Adan Mendoza found no signs of “foul play” when he spoke to local media but confirmed investigations were ongoing.
TMZ claimed Mendoza said that “gas company and fire department personnel also responded to make sure there were no toxic fumes that would endanger deputies during their search”.
Hackman’s body and that of his wife Betsy Arakawa, 63, were found when law enforcement responded to a request for a welfare check at their Santa Fe home on Wednesday.
Mendoza added when speaking to the media: “All I can say is that we’re in the middle of a preliminary death investigation, waiting on approval of a search warrant.”
The sheriff added: “I want to assure the community and neighbourhood that there’s no immediate danger to anyone.”
