If you were a soap opera fan in the 1990's you would remember the storyline between Sami Brady (Alison Sweeney) and Austin Reed - originally portrayed by Patrick Muldoon from 1992 to 1995 - as one of the most defining and dramatic arcs of "Days of Our Lives" in the 1990s. It was centered on a toxic, one-sided obsession, betrayal, and a "love quadrangle" that spanned decades, involving Sami's half-sister, Carrie Brady, and Austin's brother, Lucas Horton. Those were the days ...

Muldoon never married and did not have children. Following his death at age 57 on April 19, 2026, he is survived by his parents, his sister Shana Muldoon Zappa, and his partner, Miriam Rothbart. Muldoon was famously linked to actress Denise Richards in the late 1990s, and the two remained close friends until his death.

To see someone die at such a young age, often allows people to look at their own mortality and how to make every day meaningful.
