Child star Christian Cousins, best known for “Kindergarten Cop” and “Knots Landing,” has died. He was 43.

The actor’s brother Jonas Roeser shared the tragedy via Instagram in October.

“It’s hard to share that my brother, Christian Cousins, has passed away,” he captioned last month’s tribute, claiming Cousins suffered from liver disease prior to his passing.

Roeser noted that he didn’t meet Christian and his twin brother, Joseph “Joey” Cousins until he was in college.

“[They] are my brothers through my biological father. They grew up in California while I was in Washington,” he explained. “Before that, I grew up watching them on television in ‘Knots Landing’ and the lead role of Dominic in ‘Kindergarten Cop’ with Arnold Schwarzenegger.

“But those roles are only a small part of how I’ll remember Christian,” Roeser clarified. “He was a character, full of passion and energy, with big stories and even bigger dreams.”
