own students who may have been involved in an accusation of sexual assault at AEPi. Beyond that, it's unclear.

Anne Kirkner, a professor of criminal justice at Roosevelt University, argued that ambiguity over universities' jurisdiction can make it easier for institutions to avoid accountability for sexual misconduct, particularly when incidents involve off-campus or unrecognized fraternities and individuals who do not attend the University.

 I think these jurisdiction issues are sort of by design,  Kirkner said.  I don't think that's an accident because then it becomes unclear sort of whose domain this falls under. 

 I think a lot of schools will choose to say,  Well, that falls out of our purview,'  Kirkner said.

But Kirkner also suggested that the conduct of students who were present during the incident, referring to the group of men who cheered outside the bathroom where the assault occurred, as previously reported by the Sun-Times, could warrant scrutiny under a student code of conduct.

The University of Chicago said it will conduct its own investigation separate from the Chicago Police Department to see if school policies were violated and will initiate disciplinary actions as warranted.

What does this fraternity do to reinforce safety at its parties?

AEPi has suspended events as the investigation continues, according to the fraternity's national leadership, who also said the fraternity is fully cooperating with the investigation.

Pierce said he doesn't have information on how this party was conducted yet. But the frat's policies require guest lists for events.

When asked if this particular party had a guest list, and if the woman and the alleged perpetrator were included in the guest list, Pierce reiterated that he doesn't have details about this party.

AEPi requires training on its standards and violating them could lead to expulsion, the national chapter said in a statement.

One of the woman's friends who tried to intervene told the Sun-Times there were sober monitors at the party. One assisted the victim outside the party, but none helped as the incident was unfolding inside the fraternity, according to the friend.

The University of Chicago chapter of AEPi didn't immediately respond to requests for comment and questions about safety measures at fraternity events.

What's the history of this fraternity?

The fraternity, which is historically Jewish, has a history of making headlines for offensive reasons, including racist, misogynistic and Islamophobic emails among members of the University of Chicago chapter being leaked in 2016. In the emails, one member called a Muslim member of student government a  terrorist  while another said  dynamite and C-4  explosives were  fixtures  of Muslim culture, CBS News reported.

One student said he would celebrate  Marathon Luther King Day  by drinking all day and eating a dinner of fried chicken. A  constitution  outlining rules of dating referenced  no fatties  and a  dibs  policy on  chicks  without  competition from any of his bros,  CBS reported.

The fraternity released a statement at the time apologizing for the behavior and requiring sensitivity training for its members.

AEPi, which has more than 190 chapters in eight countries, also came under fire for reports of hazing at the University of Wisconsin - Madison this summer after 30 men were found covered in food, liquid and condiments in the basement of an AEPi fraternity house, ABC7 reported . AEPi hasn't been officially recognized by the University of Wisconsin - Madison since 2015.
