Office door of Columbia University professor, Madonna G. Constantine:

A hangman’s noose was found pinned to the door of an African-American professor’s door at Teacher’s College, administrators wrote in an e-mail today.

The noose was discovered this morning and was reported to the New York City Police Department’s Hate Crimes Task Force, members of which are currently investigating the incident. Police and University officials declined to name the professor, who the police described as a 44 year-old black woman, but students identified the victim as Professor Madonna Constantine, who is in the Psychological Counseling department and is known for her work on racism.
