Oscar-winning actor Gene Hackman died after his wife and possibly didn’t know she lay dead in their New Mexico home for a week because of his advanced Alzheimer’s, investigators have said.

Gene Hackman “was in very poor health” before his death, which was caused by heart problems and advanced Alzheimer’s disease, officials revealed on Friday. New Mexico Chief Medical Examiner Heather Jarrell shared the details of Hackman’s health in his final days at a press conference in Santa Fe alongside Sheriff Adan Mendoza.
