Haddon

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.

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.

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