Pauley Perrette and Wilmer Valderrama have paid tribute to their “NCIS” co-star David McCallum, who passed away on September 25 at the age of 90 in New York.
McCallum, the last remaining original cast member of CBS’ “NCIS,” portrayed Chief Medical Examiner Donald “Ducky” Mallard for two decades. Known for his eccentric yet highly efficient investigative skills and his knack for psychological profiling, McCallum’s character became a beloved fixture on the show.
