American University professor Sue Marcum was found murdered in her home Monday morning.

arcum was 52 years old and lived in Bethesda, Md. On Monday, police found her dead in her home, where there were signs of a forced entry and struggle. The case is being treated as a homicide, Montgomery County Police Public Information Officer D.J. Friz told The Eagle, American’s student newspaper.

arcum taught in the Kogod School of Business since 1999 and served as director of the Master of Science in accounting program.

“Professor Marcum was a beloved member of the Kogod community and her sudden death is a tremendous loss to her students and colleagues. A member of the Kogod Accounting faculty, she was a dynamic and engaging teacher,” American University Provost Scott Bass wrote in a message sent out to the campus community on Monday afternoon.

While no Georgetown faculty have been murdered in recent years, there is precedent at other universities. In 2001, two Dartmouth College professors were brutally murdered in their home by two teenagers. In 2009, an anthropology professor at SUNY-Binghamton was murdered; a doctoral student has been indicted on charges of second-degree murder.
