The hallways of the Navy Yard have always been filled with the echoes of footfalls and the “powerful lines” of justice, but as the NCIS franchise enters its landmark 2026 season, those echoes carry a deeper, more somber resonance. For over two decades, the show has been a “found family” for millions of viewers, a television institution built on the “technical precision” of its investigations and the “fierce personality” of its cast. However, the passage of time is the one adversary no agent can outrun. As we look back at the legacy of the show, we pause to honor four stars who have passed away, leaving behind a “no easy fix for grief” for the fans and colleagues they left in their wake. While the first few names are etched into the show’s DNA, the final name on this list remains a “shocking twist” that many viewers are only now beginning to process.
The first star we remember is the legendary David McCallum, whose portrayal of Dr. Donald “Ducky” Mallard was the intellectual and emotional heartbeat of the series. For twenty seasons, McCallum brought an “old rodeo cowboy” wisdom to the autopsy suite, blending medical expertise with a “Janus Protocol” of historical anecdotes and psychological insight. When McCallum passed away in late 2023 at the age of 90, it felt like the “End of an Era” for the “One Chicago” level of stability the show provided. The 2024 tribute episode was a “powerful moment” that allowed the “found family” to say goodbye to their “Elite” mentor. Ducky wasn’t just a medical examiner; he was the soul of the Navy Yard, and his absence remains a “nothing goes right” void that even the best writers can’t fully fill.
Next, we honor the “fierce personality” of Miguel Ferrer, who played Assistant Director Owen Granger in the NCIS: Los Angeles spin-off. Ferrer brought a “Dutton-style” intensity to the role, a gravelly authority that demanded respect and often created a “Clash of Titans” dynamic with the rest of the team. Ferrer’s battle with throat cancer was fought with the same “earned the hard way” grit he gave his character. He continued to film even as his voice weakened, a testament to his “technical precision” and dedication to the craft. His passing in 2017 was a “powerful line” in the sand for the franchise, reminding fans that the “real story” of heroism often happens behind the scenes in the face of personal tragedy.
The third name on our list is Pauley Perrette’s beloved on-screen father figure, Ralph Waite, who played Jackson Gibbs. As the father of Leroy Jethro Gibbs, Waite provided the “old rodeo cowboy” foundations that explained the stoic nature of the show’s lead. His appearances were always a “birthday worth celebrating,” providing a “Janus-style” look into the past of a man who rarely shared his feelings. When Waite passed away in 2014, the show integrated his death into the Season 11 finale, titled “Honor Thy Father.” It was an “intense moment” that showcased the “no easy fix for grief” that comes with losing a patriarch, serving as one of the most “extremely moved” episodes in the show’s history.
Finally, we come to the fourth name, which remains unexpected for many casual viewers: Lisa Sheridan. While many associate NCIS with its long-term regulars, the show’s strength has always been its “infamous first meetings” with guest stars who leave a lasting impact. Sheridan, a seasoned actress known for her “fierce personality” and ethereal beauty, appeared in the early seasons of NCIS as Amber Rivers. Her “technical precision” in the role helped define the high-stakes “drama” that the show would become known for. Her unexpected passing in 2019 at the young age of 44 sent a “chaos at the bunkhouse” shockwave through the community of actors who had worked alongside her. For many who revisit the early “Stellaride” style episodes of the mid-2000s, seeing her face is a “powerful moment” of realization regarding how many talented souls have contributed to this “found family” before their time was up.
As NCIS moves forward into its 2026 missions, the “intensity” of the cases remains, but these four stars remind us that the “real story” is the people. Justice is “earned the hard way,” and it is built on the shoulders of those who came before. Their legacies are not just found in the “technical precision” of their performances, but in the “found family” of fans who continue to watch, remember, and honor their work. Tonight’s the night where we look back, not with the “nothing goes right” sadness of loss, but with the “powerful” gratitude for the time they spent with us at the Navy Yard.
