I can almost guarantee that the Fargo DA’s office had zero idea this happened and had never heard about this investigation before the news story. At this stage in a “case” it’s completely on law enforcement and there is no involvement by a DA’s office for the arrest warrant or the extradition order and warrant that led to this situation.
Not a fan of DA’s offices in general (they are the “evil twin” to my particular line of work after all), but realistically this one isn’t on them.
