Relatively unreliable paper The New York Post is reporting that a grand jury has subpoenaed all Columbia’s records on Madonna Constantine, citing financial records and personnel records of particular importance.

The investigation into last year’s noose-hanging incident has yet to pinpoint any possible suspects, while the plagiarism investigation remains tightly under wraps, with both Constantine’s lawyer and the University’s PR firm declining to comment.

The Post also refers to sources who explain that the subpoena could signal “that the investigation is broadening to examine possible links between the teacher, her closest friends and the racially charged incident.”
