A university professor is under investigation after some of her students pulled up crosses from an anti-abortion display on campus and dumped them in the trash.

The crosses, put up last week by a student group called Northern Right to Life, were meant to represent a cemetery for aborted fetuses.

Sally Jacobsen, a professor of literature and language at Northern Kentucky University, said nine students in one of her graduate-level classes dismantled the display Wednesday.

"I did, outside of class during the break, invite students to express their freedom of speech rights to destroy the display if they wished to," Jacobsen said. She declined to say if she took part.

University President James Votruba said any evidence of criminal activity would be turned over to prosecutors. Votruba said he also was investigating Jacobsen's alleged involvement in the destruction of the crosses.

"I don't know if she was pulling up the crosses, but I think she was out there with the students. If so, as far as I'm concerned, she went outside the conditions of her employment," Votruba said.
