If the alias was drawn from this source, it would suggest that the hijacker had either been exposed to French-language Canadian or Belgian culture, had contacts in French-speaking communities, or had some other access to material that was not commonly available in the United States in 1971. This has led some researchers to speculate about Canadian connections, French-Canadian backgrounds, or time spent in French-speaking environments.
The FBI has not confirmed this connection as an established lead. It remains a hypothesis—one that is internally consistent but has not been verified with evidence. It is possible the name was chosen for reasons entirely unrelated to the Belgian comics. It is also possible the choice was deliberate and meaningful. Without additional evidence, the question cannot be resolved.
The name “Dan Cooper” is, in any case, clearly an alias. The man who bought the ticket did not use his real name, and his real name has never been established.

## What the 2016 Suspension Meant—and What It Didn’t
In July 2016, the FBI formally announced that it was redirecting active investigative resources away from the D.B. Cooper case. The announcement came from the Seattle field office, which had been the primary home of the investigation for forty-five years.
The statement was precise about what was changing and what was not. Active investigation—the work of assigning agents to pursue leads, develop suspects, and advance new theories—was being suspended. The FBI explicitly noted that it would continue to accept and evaluate physical evidence, particularly items potentially tied to the parachutes or the ransom money. The case file remained open in the sense that no one had been charged and the crime was still technically unresolved.
