In a statement, Carradine’s family announced his death “with profound sadness”, adding that the US actor was a “beloved father, grandfather, uncle, and brother”.
“In a world that can feel so dark, Bobby was always a beacon on light to everyone around him,” they said.
“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.”
The statement added: “At this time we ask for the privacy to grieve this unfathomable loss. With gratitude for your understanding and compassion.”
In his own separate statement to Deadline, Carradine’s brother Keith added: “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.”
