Patrick Muldoon’s Cause Of Death Confirmed
Patrick Muldoon’s cause of death has been confirmed following his tragic passing.
Muldoon, the actor best known for his roles in Days of Our Lives, Melrose Place, and Starship Troopers, has died suddenly at the age of 57 — prompting an outpouring of tributes from fans, co-stars, and those who knew him both on and off screen.
The news of his passing, confirmed on Monday, April 20, came as a shock to many, not least because of how active and engaged Muldoon had remained in both his professional and personal life right up until his death.
Just days earlier, he had been posting enthusiastically about upcoming projects, giving little indication of the tragedy that was about to unfold.
As the entertainment world reacts to the loss, new details have begun to emerge — not only about the circumstances of his death, but also about the life and legacy he leaves behind.
A career that defined a generation of television
Born in San Pedro, California, Patrick Muldoon first rose to prominence in the early 1990s, becoming a familiar face to millions of viewers through his work in television.
His breakthrough came in 1992 when he was cast as Austin Reed on the long-running NBC soap opera Days of Our Lives.
The role quickly made him a fan favorite, with his character’s romantic storyline capturing the attention of audiences across the country. Muldoon remained on the show until 1995, later returning to reprise the role in 2011.
Following his initial success, he went on to star in another iconic series, Melrose Place, where he played Richard Hart — a character remembered for his darker, more volatile storylines.
His transition between daytime and primetime television demonstrated his versatility as an actor, allowing him to build a career that spanned multiple genres.
Beyond television, Muldoon also made his mark on the big screen. In 1997, he appeared in the sci-fi film Starship Troopers, taking on the role of Zander Barcalow, a romantic rival to the film’s lead.
Though the movie initially received mixed reviews, it has since gained cult status, further cementing Muldoon’s place in pop culture history.

A life beyond the screen
While many knew him for his acting, Muldoon’s interests extended far beyond Hollywood.
He was also a musician, serving as the lead vocalist for his band, The Sleeping Masses. Friends and collaborators often described him as passionate, creative, and deeply engaged with his art, whether on set or on stage.
In addition to performing, Muldoon worked behind the scenes as a producer on several films, including The Tribes of Palos Verdes, Arkansas, Marlowe, and The Card Counter.
More recently, he had been involved in the upcoming film Kockroach, which stars Chris Hemsworth, Taron Egerton, and Zazie Beetz.
Just two days before his death, Muldoon shared his excitement about the project on social media, writing about how thrilled he was to be part of the production, which was filming in Australia.
For many, that post has taken on a poignant significance — a reminder of how sudden and unexpected his passing truly was.
Muldoon’s personal life also drew attention at times, particularly during his past relationship with actress Denise Richards.
Their romance, which took place years before Richards’ marriage to Charlie Sheen, remained a topic of discussion long after it ended — largely because of the strong friendship they maintained, per Bravo.
Richards has spoken openly about the dynamic between the two men, revealing that during her marriage to Sheen, she was discouraged from speaking to Muldoon. Despite that, she later reconnected with him, describing their bond as a deep friendship that endured beyond their romantic past.
In recent years, the pair even reunited professionally, appearing together in a music video — a collaboration that reflected the easy rapport they had maintained over time.
Those close to Muldoon say relationships like these were a testament to his character — someone who valued connection and remained on good terms with people from all stages of his life.

Tributes pour in from friends and co-stars
In the hours following the announcement of his death, tributes began flooding social media from those who had worked with Muldoon over the years.
Actor Jake Getman, who appeared alongside him as a child, shared a heartfelt message recalling their time together.
“RIP Patrick Muldoon,” he wrote. “Worked with him when I was 8… a great guy and always kept the energy light.”
Others described him as generous, charismatic, and full of life — someone who made a lasting impression both professionally and personally. Friends spoke of his warmth, his humor, and his ability to make people feel at ease.
To many, he was more than just a co-star; he was a friend, a mentor, and a presence that brought energy into every room he entered.
He is survived by his partner, Miriam Rothbart, as well as his parents, sister, brother-in-law, and extended family.
The sudden loss that shocked fans
What has made Muldoon’s death particularly difficult for fans to process is just how sudden it appears to have been.
There were no widely reported signs of serious illness. No indication that anything was wrong.
Instead, the last public glimpses of the actor show someone fully engaged with his work and looking ahead to future projects. His recent social media activity painted a picture of optimism — of someone still deeply invested in his career and excited about what lay ahead.
That contrast has only deepened the sense of shock surrounding his passing.
As tributes continue and more details emerge, the circumstances surrounding Patrick Muldoon’s sudden passing have now been confirmed.
According to People, the actor died after suffering a heart attack on Sunday, April 19. He was 57 years old.
