Overview

• Betsy Arakawa’s autopsy confirmed she died in mid-February 2025 from hantavirus pulmonary syndrome, with heavy, fluid-filled lungs and mild vessel hardening.
• Gene Hackman’s autopsy revealed death from hypertensive and atherosclerotic cardiovascular disease, with advanced Alzheimer’s disease as a contributing factor.
• Both tested negative for COVID-19, flu, intoxicants, and carbon monoxide exposure, and no signs of trauma were found in either body.
• Investigators found extensive rodent infestation on the property, including droppings in garages and outbuildings, confirming hantavirus exposure risks.
• Hackman, 95, died roughly a week after Arakawa, 65, likely unable to respond to her death due to his advanced Alzheimer’s condition.
