The state doesn't allege that Beebe was a member, and the article doesn't say that they do.  Pay attention": The state alleges that a member, acting as bartender, administered the drug, and the article reports that.  This isn't simply a rape that happened to take place in a fraternity house, nor a rape that happened to take place in a fraternity house during a fratenity-sponsored party; the chapter's bartender is alleged by the state to have been an accesory to the rape, and it is alleged by the state to have been a gang rape.  All that has been in front of you and plainly stated all the time. —←T
