Fraternity investigated over ‘date rape’ drug allegations

A fraternity at the University of Wisconsin-Milwaukee is being investigated on suspicion that members put “date rape” drugs into drinks served at a party, according to search warrants issued by campus police.

Police started investigating after three women and a man were hospitalized after consuming drinks at the September 12 party at the Tau Kappa Epsilon house, the search warrant said. The warrants sought, among other things, drugs that cause loss of memory or “other intoxicating effects.”

One student who went to the hospital told police that “she had a weird feeling and sensation prior to blacking out which she had never felt before. [The student] stated she feels victimized by TKE and that she is sure some sort of drug or other intoxicant was given to her against her will and unbeknownst to her,” according to the warrant.

The student said the fraternity had a reputation for putting “roofies” into women’s drinks but “she thought it was all in the past,” the warrant stated. Roofies, a street name for Rohypnol, is a tasteless and odorless drug.

Alex Baker of the Tau Kappa Epsilon International Fraternity said: “… These alleged actions do not align with our values of love, charity and esteem.
