Calvary Rogers, a freshman at the university, first brought the group to the administration's attention. Soon after, however, numerous students began posting their own reactions to the group on social media.

By 3:40, the University had determined that the OP "appears to based in Oklahoma" and that the school was working with authorities to determine the origin of the posts. "Our police and information security staff are trying to locate the exact source," Penn spokesperson Ron Ozio said over email to BillyPenn, "and see what steps can be taken to cut the account off."

The Penn student body doesn't appear to be backing down either. A number of students have already gathered at the The Vice Provost for University Life offices on campus to organize and protest against the messages. Even the Penn College Republicans have spoken out against the matter.

"These messages are absolutely despicable," a statement from the student group reads. "Hate such as this has no place on Penn's campus or in our nation. Our thoughts and prayers are with those affected, and we hope that Penn administration and Penn police find the perpetrators as soon as possible."

Update: According to Penn administrators, a student at the University of Oklahoma has been suspended while the school probes his involvement with the GroupMe campaign.
