While the public grapples with the loss, new revelations have emerged regarding the final moments of the 57-year-old actor. As TMZ reports, according to his sister, Shana Muldoon-Zappa, Muldoon had spent Sunday morning drinking coffee with his girlfriend in their Beverly Hills home. After their morning routine, he went to take a shower. When he did not emerge for an unusually long time, his girlfriend checked on him and found him unconscious on the bathroom floor.
Despite the rapid response of paramedics who rushed to the scene to attempt resuscitation, there was nothing that could be done, as it was reported to be a fatal heart attack, as per Deadline as well.
Long before he was a household name, Muldoon was a standout athlete, a San Pedro native who graduated from USC, where he played for the legendary Trojans football team. While his physical presence made him a natural for the screen, his personal life remained relatively private. Unlike the tangled romances of his television characters, Muldoon never married and did not have children, often dedicating his time to his close-knit family and his various creative endeavors in both music and film.
While his personal life was one of quiet stability, his professional journey was a high-octane ascent that saw him evolve from a college athlete into a titan of both the small and silver screens.
