New Mexico medical investigators revealed that Ms. Arakawa likely passed on February 11, and her husband followed on February 18, although it is suspected that he might not have been aware of her passing due to his Alzheimer's condition. Local health officials noted that hantavirus infections are extremely rare, with only 136 cases identified in New Mexico over the past 50 years, resulting in a 42% mortality rate. Investigations are ongoing to establish how Ms. Arakawa contracted the virus, while Hackman reportedly tested negative for the disease.

The couple, who had shared over three decades of marriage, were found by a welfare check conducted by neighborhood security, leading to the discovery of their bodies in an advanced state of decomposition. Both their bodies showed no signs of foul play or forced entry, and investigations are still probing the home environment for potential risk factors. Gene Hackman leaves behind three adult children from a previous marriage, while he and Arakawa were known for their supportive relationship throughout the years.
