Betsy Arakawa was a classical pianist, creative partner and supportive wife who loved watching DVDs with her husband Gene Hackman.

Authorities say there were no signs of foul play, but the circumstances are “suspicious enough” to warrant a full investigation into the cause of death.

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.
