The Blue Bloods franchise has mourned the deaths of some cast members over the years.
The CBS show, which aired from 2010 to 2024, followed the lives of the Reagan family, many of whom work for the NYPD under the leadership of NYC police commissioner Frank Reagan (Tom Selleck). Frank’s father, Henry Reagan (Len Cariou), was also central to the show, alongside Frank’s children: daughter Erin Reagan (Bridget Moynahan) and sons Danny (Donnie Wahlberg) and Jamie Reagan (Will Estes).
After Blue Bloods came to an end, CBS announced spinoff Boston Blue, which follows Wahlberg’s character taking a position with the Boston P.D. He is then paired with detective Lena (Sonequa Martin-Green), the eldest daughter of a prominent law enforcement family.
Since Blue Bloods became a household name, the cast has mourned numerous costar deaths. The CBS show often featured tribute cards at the end of episodes with executive producer Leonard Goldberg and star Treat Williams receiving dedications.
In March 2026, news broke that Alex Duong died from a rare form of cancer after previously playing criminal and gang leader Sonny Le.
“We are overwhelmed with gratitude — because of you, we have already reached the original goal. Thank you from the bottom of our hearts,” a message read on a fundraiser page for Duong. “At the same time, with Alex passing, Christina’s situation has become more serious and the financial needs ahead are much greater than we could have anticipated. Alex’s memorial service, Everest ‘s education needs, ongoing care, daily support, and what lies ahead for his family mean we must continue raising funds beyond this initial goal.
The statement continued: “If you’ve already given, thank you — truly. If you’re able to share or contribute again, it would mean everything right now. Please keep Alex and his family in your prayers. Your support is carrying them through the hardest time of their lives. We will update you with respect to details of his ‘Celebration of Life.’”
