Actress and model Dayle Haddon has died and another person has been hospitalised due to a carbon monoxide leak at a home in Pennsylvania, authorities have said.

Haddon modelled 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 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 a critical condition at a hospital in New Jersey – 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 Marc Blucas, according to the BBC’s US partner, CBS News.

A preliminary investigation found that a faulty exhaust pipe on the building’s heating system caused the leak, police said.

They added that the high levels of carbon monoxide in the property had affected emergency responders, with two medics hospitalised with carbon monoxide exposure and a police officer treated at the scene.

Dayle Haddon was born and raised in Quebec, Canada, and began a career as a ballerina.

She moved to the US to pursue a modelling career, and later worked in cinema, featuring 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 Dayle had “a pure heart” and “a life well lived”.

“She was a woman in her power, yet soft and attentive to all. Deeply creative and curious, gifted with beauty inside and out. Always kind and thoughtful,” she said.

“She was a high-hearted spiritual being that put value on her soul’s evolution, so I know her journey here in this dimension must have been complete.”
