Dayle Haddon, who modeled for decades and simultaneously had a dual career as an actress, has died at the age of 76.

Haddon, who co-starred on screen with Nick Nolte at the height of her career, died of suspected carbon monoxide poisoning, NBC10 in Philadelphia reported Friday.

Bucks County Emergency Services reportedly received a call around 6:30 a.m. that day after a man was seen unconscious on the floor of a detached in-law suite in Solebury Township, Pennsylvania.
