When my mom watched NCIS my three favorite characters were Tony Ziva and Ducky and I would like to know why Ducky left NCIS? I always thought Ducky was very smart and proper and NCIS should've kept him. My mom told me that Ducky's actor passed away and that's why Ducky left. Is Ducky's actor still alive and what's the story behind Ducky's departure on NCIS?
