Gene Hackman and his wife, Betsy Arakawa, tested negative for carbon monoxide poisoning, the Santa Fe Sheriffs Department in New Mexico said Friday, one day after they were found dead with their dog.

Legendary actor Gene Hackman, 95, and wife Betsy Arakawa, 64, and their dog were found dead in their home outside Santa Fe, authorities say.

Arakawa “hadn’t called” her 91-year-old mother, Yoshie Feaster, who suffers from dementia, since October, according to the elder’s housekeeper, Keiko. Keiko spoke to Daily Mail on Friday, just two days after Hackman, 95, and Arakawa, 65, were found dead in their Santa Fe, New Mexico, home, along with a deceased dog.
