Dateline NBC returns on Friday, March 6, 2026, with a new episode titled “The Professor & The Poet.” Reported by longtime correspondent Josh Mankiewicz, the broadcast examines the murder of Sue Marcum and the investigation that followed. The case drew attention for its complex personal relationships and the surprising secrets that investigators uncovered along the way.
The episode focuses on the life of Sue Marcum and the circumstances surrounding her death. As detectives began piecing together the timeline of events, they also worked to understand the people who were closest to her.
