Betsy Arakawa — the classical pianist married to Gene Hackman — died last month of hantavirus pulmonary syndrome, a rare infectious disease linked to rodents, New Mexico authorities announced Friday.

Gene Hackman died of cardiovascular disease about a week after his wife died of hantavirus, according to the New Mexico medical examiner.

The partially mummified bodies of Hackman and his wife, Betsy Arakawa, were discovered in February at their home in New Mexico.
