A 19-year-old female student told police she was raped on campus by two male friends.

The student said she had been drinking and playing cards with the men at about 1:30 a.m. and had passed out, MSU police Detective Tony Willis said. When she woke up about three hours later, she was naked and the men were getting dressed, he said.

Willis did not have any other information about the incident, which was reported Wednesday, but said it remains under investigation. Police have yet to contact the two men, he said.

He said most sexual assaults on campus are instigated by someone the victim knows.

“I would say 80 percent, and a large number involve alcohol,” Willis said.

Two other cases of rape have been reported on campus since January. Both of those cases involved alcohol.

But Karyn Price, sexual assault counseling staff coordinator at The Listening Ear, said people need to be careful not to blame rape victims for the crime because they may have been drinking.

She said many women who are raped fail to report the crime out of fear or embarrassment.

“They feel ashamed and feel guilty because society makes them feel guilty for the clothes they wear, or because they were drinking or because they went to a man’s room alone,” she said.

The Listening Ear, 1017 E. Grand River Ave., offers 24-hour counseling services, including help for victims of sexual assaults.

Experts estimate nearly 50 sexual assaults occur on campus each year, although most go unreported. Nine cases of criminal sexual conduct on varying levels were reported on campus last year, according to the Department of Police and Public Safety.
