The Santa Fe County Sheriff's Office spoke with reporters on Friday about the investigation into Gene Hackman and his wife's deaths. The Oscar-winning actor, Betsy Arakawa and one of their dogs were found dead in their New Mexico home on Wednesday.

Gene Hackman and his wife Betsy Arakawa tested negative for carbon monoxide in the initial results of the toxicology report, leading officials to rule out the gas as a cause of Hackman and Arakawa’s death, Sheriff Adan Mendoza said in a press conference on Friday.
