NEW HOPE, Pa. (AP) — Dayle Haddon, an actor, activist and trailblazing former “Sports Illustrated” model who pushed back against age discrimination by reentering the industry as a widow, has died in a Pennsylvania home from what authorities believe was carbon monoxide poisoning.

First responders were called to the property just after 6:30 a.m. Friday after receiving reports of a 76-year-old man lying unconscious on the first floor of the suite, the Solebury Township Police Department said.
