Actor Gene Hackman died of heart disease a full week after his wife died from hantavirus in their New Mexico home, likely unaware that she was dead because he was in the advanced stages of Alzheimer’s disease, authorities revealed Friday.

For years, actor Gene Hackman’s doting wife Betsy Arakawa would do whatever she could to help keep him healthy, whether it meant wearing a mask everywhere she went or encouraging him to stay fit by riding his bike or doing yoga on Zoom.
