Sheriff Adan Mendoza believes the beloved Hollywood icon was alone with his dead wife for days before his passing.

There was no food present in Hackman’s stomach at his time of death, meaning he had not eaten recently. He tested negative for hantavirus.

The late actor, along with wife Betsy Arakawa, were found dead inside their New Mexico home on Feb. 26.

Authorities were called to the home after a pest control worker called a neighborhood security officer when he stopped by and couldn’t get ahold of anyone.

The security officer immediately called 911 when he peeked in a window and saw their bodies lying on the floor.
