Actress Dayle Haddon Dies from Suspected Carbon Monoxide Poisoning

Dayle Haddon, a Canadian actress and model, was found dead on Dec. 27 from suspected carbon monoxide poisoning at a Pennsylvania property owned by her son-in-law, actor Marc Blucas.

Emergency responders arrived at the Solebury Township home after a 6:30 a.m. 911 call reporting an unconscious man. Haddon, 76, was discovered in a second-floor bedroom and pronounced dead, while a 76-year-old man was hospitalized. Responders detected dangerously high carbon monoxide levels, and two medics were also treated for exposure.

Haddon gained fame as a model for brands like L’Oréal and Revlon and appeared in films such as Madame Claude and North Dallas Forty. She later founded WomenOne, a nonprofit promoting girls’ education globally.

Blucas, known for roles in Knight and Day and Buffy the Vampire Slayer, co-owns the home with his wife, journalist Ryan Haddon.

Authorities stress the importance of carbon monoxide alarms, particularly during winter, as exposure to high levels can quickly become fatal. Homeowners are urged to ensure alarms are functioning and seek help if alarms activate.
