Ryan Caskey, 21, a politics major and cadet in the Reserve Officers' Training Corps program at University of San Francisco, stands accused of raping four students over the last few months. If you recall, Caskey was arrested Thursday on the USF campus. He now sits in county jail facing four felony counts of rape and assault. He has also been suspended from school.

According to San Francisco police spokesman Wilfred Williams, the victims, who were given counseling, "were all acquaintances of Caskey's." CBS 5 reports that police are asking anyone else who might have been a victim of the suspect to contact SFPD's Sex Crimes Detail at 415-553-1361.
