A University of Wisconsin-Milwaukee fraternity is suspected of spiking drinks with the so-called date rape drug during a party. Police opened the investigation when three women and a man were hospitalized after having drinks at a Tau Kappa Epsilon house party earlier this month. So far, one student has been arrested in connection with the incident. This isn't the first run-in with the law for the fraternity. Last year, its members were investigated for three sexual assault reports.
