The Oscar-winning actor's will was released after he and his wife, Betsy Arakawa, died within days of each other
The fate of Gene Hackman's $80 million fortune remains uncertain as his three children were not named as beneficiaries in the actor's will.
Hackman and his wife, Betsy Arakawa, were found dead in their home in Santa Fe, New Mexico in late February, prompting an investigation into the couple's mysterious deaths.
Earlier this month, Dr. Heather Jarrell, chief medical investigator for the state's Office of the Medical Investigator, announced that Arakawa was likely first to have died around February 11, when she passed away from a rare condition called hantavirus pulmonary syndrome.
Hackman, who had been diagnosed with Alzheimer's disease, is believed to have died around one week after his wife due to 'hypertensive and atherosclerotic cardiovascular disease, with Alzheimer's disease as a significant contributory factor'.
Jarrell explained: "Mr. Hackman showed evidence of advanced Alzheimer's disease. He was in a very poor state of health. He had significant heart disease, and I think, ultimately, that is what resulted in his death."
Hackman's will has been released in the wake of his passing, and reveals that the Oscar-winner left his entire estate to Arakawa.
