SOLEBURY TWP. Pa. (WPVI) – A Canadian model and actress have died and another man is in hospital after a suspected carbon monoxide leak in Solebury Twp., Bucks County.

Shortly after 6:30 a.m. Friday, a 911 call came in about a 76-year-old man lying semi-conscious on the first floor of a cottage on a property in the 6900 block of Phillips Mill Road.

Paramedics got the man out of the building and quickly took him to the hospital.

Then rescuers learned of a 76-year-old woman who was also in the house. They found her unconscious in a second-floor bedroom and attempted to revive her, but she was pronounced dead at the scene.

Family members in the main house on the property were not affected.

The Bucks County coroner identified the 76-year-old as Dayle Haddon, who rose to international fame in the 1970s and graced the covers of fashion magazines.

She was featured in Vogue in August. She also starred in films and has been involved in numerous causes in recent years.

“She was chic and elegant. She always remembered you,” Sandy Linter, a renowned makeup artist and longtime friend of Haddon, said in an exclusive interview with Action News. “It was a tragic accident. I’m sorry. I’m so sorry for her family.”

Firefighters on scene discovered high levels of carbon monoxide in the property. Police believe fumes from a boiler could be responsible.

“A heating unit, a boiler, is believed to be the source of the carbon monoxide. The initial readings when EMS and firefighters arrived were extremely high, so we are treating this as a carbon monoxide poisoning incident,” said Det. Sgt. Jonathan Koretzky of Solebury Twp. Police Department.

Two paramedics and a Twp from Solebury were taken to Doylestown Hospital for carbon monoxide exposure. The police officer was treated at the scene.

The circumstances surrounding this incident remain under investigation.

Real estate records show the home is owned by actor Marc Blucas and his wife, journalist and producer Ryan Haddon Blucas. They purchased the property in 2012 for $1 million.

Marc Blucas appears in an interview with the Hallmark Channel discussing the renovation of the 18th century home. He is known for roles in the films “Buffy the Vampire Slayer” and “Hallmark.”

On Friday evening, Dayle Haddon’s daughter Ryan posted a tribute on Instagram: “She stood up to so many, saw that her greatness was sometimes hidden from them, and always built bridges with her own connections to help them rise. She was everyone’s biggest champion.” . An inspiration for many.”

Fire officials want to remind the public that carbon monoxide is odorless, colorless and tasteless. It can be dangerous all year round, but especially in the colder months. They say prevention and detection are key.

“Prevention is about keeping your heaters, appliances, fireplaces, water heater and chimneys in good working order. Detection is about having a working, at least one working, carbon monoxide detector in the home,” said New Hope Eagle Fire Company Deputy Chief Mark Nissenfeld.
