Actor Robert Carradine's cause of death was officially ruled to be a suicide, according to the Los Angeles County Medical Examiner.

Carradine, best known for roles in Lizzie McGuire, Revenge of the Nerds and The Long Riders, was previously reported to have died by suicide on February 23.

"It is with profound sadness that we must share that our beloved father, grandfather, uncle, and brother Robert Carradine has passed away," the Carradine family said in a statement obtained by Deadline. "In a world that can feel so dark, Bobby was always a beacon on light to everyone around him. We are bereft at the loss of this beautiful soul and want to acknowledge Bobby’s valiant struggle against his nearly two-decade battle with Bipolar Disorder. We hope his journey can shine a light and encourage addressing the stigma that attaches to mental illness. At this time we ask for the privacy to grieve this unfathomable loss. With gratitude for your understanding and compassion.”

Carradine's brother, Keith, referred to him as the bedrock of the acting family and reiterated that he fought valiantly with Bipolar Disorder throughout his life.

“We want people to know it, and there is no shame in it,” Keith said via Deadline. “It is an illness that got the best of him, and I want to celebrate him for his struggle with it, and celebrate his beautiful soul. He was profoundly gifted, and we will miss him every day. We will take solace in how funny he could be, how wise and utterly accepting and tolerant he was. That’s who my baby brother was.”

Robert was the youngest of actor John Carradine's five children, with brothers Keith and the late David Carradine also working as actors, while Chris Carradine worked as the Vice President of Walt Disney Imagineering. Robert made his film debut in the 1972 film The Cowboys alongside the late legendary actor John Wayne before later starring alongside David and Keith in The Long Riders.

Robert later starred as Lewis in the 1984 comedy film Revenge of the Nerds and as Sam McGuire, the father of Hilary Duff's titular character in all 65 episodes of Lizzie McGuire, as well as The Lizzie McGuire Movie (2003) and two episodes of the Lizzie McGuire reboot in 2020 during an acting career that spanned six decades.
