Fonda’s representative confirmed his death to the Hollywood Reporter.
“It is with deep sorrow that we share the news that Peter Fonda has passed away,” his family said in a statement to People.com.
“The official cause of death was respiratory failure due to lung cancer,” the statement added. “In one of the saddest moments of our lives, we are not able to find the appropriate words to express the pain in our hearts. As we grieve, we ask that you respect our privacy.”
“I am very sad,” Jane said in a separate statement to Variety. “He was my sweet-hearted baby brother. The talker of the family. I have had beautiful alone time with him these last days. He went out laughing.”
