During a 1991 interview, Landon told Life magazine he was determined to fight as hard as he could. “I’m not the kind of person who gives up without a fight,” he said. “If I’m gonna die, death’s going to have to do a lot of fighting to get me. I’m not just gonna lie down and let it happen.”

Victor French

Victor French died at the age of 54 on June 15, 1989. He reportedly died from lung cancer. However, according to Grassle, Landon believed French died from alcoholism.
