MSU police are investigating three sexual assault cases occurring within one week on campus.

The first case involves two female students who say they were sexually assaulted in Sundance Apartments Sept. 18.

The second case involves another coed who says she was sexually assaulted in Killingsworth Sept. 24. MSU police were alerted to the assault after WFPD officers took the victim to United Regional Hospital.

In the Sept. 18 case, the victims approached campus police about 6 p.m. to report the alleged assault. They were later treated at a hospital.

Dan Williams, chief of police, said police currently have a person of interest in the case but no suspects.

Students were informed of one of the ongoing investigations Friday afternoon in a campus-wide email sent by MSU police.

According to the email, the person of interest in the Sept. 18 case may have used Rohypnol, a date rape drug, on the victims. Though police said they haven’t found evidence confirming these drugs were used, one of victims had the usual symptoms, Williams said.

“In one case, the victim reported symptoms consistent with the use of these substances: a rapid onset of intoxication out of proportion to what they may have had to drink and reported memory loss,” the email said.

Both victims in the Sept. 18 case said the alleged assaults occurred in the same room at the same time.

“The phenomenon of drugs being used to facilitate sexual assault has been widely reported across the country,” the email said. “Although no confirmed cases have previously been reported on campus, the MSU Police Department urge the campus community to be alert to the possibility and take steps to protect themselves.”

Some common date rape drugs are Rohypnol, GHB, and Ketamine. They often have no color, smell or taste, which can make them dangerous. Some symptoms are dizziness, rapid intoxication and memory loss.

“In this condition, anyone can be extremely vulnerable to sexual assault,” police said.

In March, a female reported to MSU police that she had been sexually assaulted, but later dropped the charges.
