Oscar-winning actor Gene Hackman, 95, and his wife, classical pianist Betsy Arakawa, 65, were found dead Wednesday in their Santa Fe, New Mexico, home, authorities confirmed to HuffPost. One of the couple’s dogs also died.

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.

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.
