Kieran Culkin has opened up about his older sister Dakota Culkin’s tragic death, and revealed the sweet way that he honored her during his time on Succession.

Speaking about his close relationship with his siblings on the show, Kieran said: “We lived in a tight space where it was just seven of us running around. It was like a sort of little wolf-pack mentality.”

But in December 2008, the Culkin siblings were struck by tragedy when Dakota, aka “Cody,” was hit by a car while crossing Lincoln Boulevard in Marina del Rey, California, and died at age 29.

“After a couple seasons on Succession, I realized there was some stuff that Roman did that I was like, ‘Oh, that’s my sister. That was her sense of humor,’” he shared. “She could find exactly what the right thing to make fun of you was that would get to you, but be really funny and make the room laugh. That was her.”

Meanwhile, Kieran’s brother Macaulay honored their late sister when he and his fiancée, Brenda Song, welcomed their first child in 2021. The two named their baby boy Dakota in his sibling’s memory.

Kieran previously opened up about Dakota’s death in a 2021 profile with The Hollywood Reporter, where he said: “That’s the worst thing that’s ever happened, and there’s no sugarcoating that one.”
