Actress and model Dale Haddon has died and another person was hospitalized after a carbon monoxide leak in a home in Pennsylvania, authorities said.
Haddon modeled for brands including Estée Lauder and L'Oreal and appeared on the covers of magazines including Sports Illustrated and Vogue Paris in the 1970s.
Police said they received a call at 06:31 local time (01:31 GMT) on Friday reporting that a 76-year-old man had passed out on the first floor of a self-contained detached 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 at a New Jersey hospital, has been 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 the BBC's US partner, CBS News.
A preliminary investigation determined that a faulty exhaust pipe on the building's heating system caused the leak, police said.
They added that high levels of carbon monoxide at the property affected emergency crews, with two medics hospitalized with carbon monoxide exposure and a police officer treated at the scene.
Dale Haddon was born and raised in Quebec, Canada and began her career as a ballerina.
She moved to the US 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.
Paying tribute to her mother, Ryan Haddon wrote on Instagram that Dale had a “pure heart” and “a life well lived.”
“She was a woman in her strength, but soft and considerate to everyone. Highly creative and curious, gifted with beauty inside and out. Always kind and considerate,” she said.
“She was a high-hearted spiritual being who valued her soul's evolution, so I know her journey here in this dimension must have been complete.”
