Model Dayle Haddon died in a suspected carbon monoxide leak at the Bucks County home of her son-in-law, Hallmark movie star Marc Blucas, officials said.

Dayle Haddon, the only model to have had four major cosmetics contracts, died Friday.

Marc Blucas spoke about renovating the 1700s home that his mother-in-law Dayle Haddon would later die in during a resurfaced 2016 interview with the Hallmark Channel.
