Actress and model Dale Haddon has died, and another person was hospitalized due to a carbon monoxide leak at a home in Pennsylvania, authorities said.
Haddon modeled for brands including Estée Lauder and L'Oreal, and appeared on the front of magazines including Sports Illustrated and Vogue Paris in the 1970s.
Police said they received a phone call at 06:31 local time (01:31 GMT) on Friday reporting that a 76-year-old man had lost consciousness on the first floor of a detached, free-standing building at a home in Bucks County.
A 76-year-old woman, later identified as Haddon, was found dead in a second-floor bedroom.
The man — who police described as being in critical condition in a New Jersey hospital — was identified as Walter J. Blucas, whose son is married to Haddon's daughter.
Records show the home is owned by Haddon's daughter, former journalist Ryan Haddon, and her husband, actor Mark Blucas, according to CBS News, the BBC's US partner.
A preliminary investigation found a defective exhaust pipe in the building's heating system was the cause of the leak, police said.
They added that the high levels of carbon monoxide at the property affected emergency responders, with two paramedics being taken to hospital due to exposure to carbon monoxide and a police officer being treated at the scene.
Dale Haddon was born and raised in Quebec, Canada, and began her career as a ballet dancer.
She moved to the United States to pursue a modeling career, and later worked in film, appearing in films including The World's Greatest Athlete, released in 1973, and North Dallas Forty, released in 1979.
Honoring her mother, Ryan Haddon he wrote on Instagram That Dale had a “pure heart” and a “good life.”
“She was a powerful woman, yet soft and attentive to everyone. Very creative and curious, gifted with beauty inside and out. She was always kind and thoughtful,” she said.
“She was a kind-hearted spiritual being who placed a value on the evolution of her soul, so I know her journey here in this dimension must have been complete.”
