Student leaders at the University of Michigan said that the self-governing Greek Council was effectively working toward sanctions for the fraternities and sororities involved in the vandalism of two northern Michigan ski resorts in January, but also called for Michigan State Police, national Greek organizations, and the university leadership to take their own actions against the groups and individuals involved.

Alexander Krupiak, the president of U-M's Interfraternal Council, said the events that took place at Treetops and Boyne resorts during the weekend of Jan. 16-18 were inexcusable and shed an extremely negative light on the university.

He and Madeline Walsh, the president of the PanHellenic Association, each offered apologies to the Board of Regents Thursday evening during the regents' meeting, and also offered apologies to the entire U-M community.

"We have been collectively embarrassed and humbled by the actions of some of our members," Krupiak said.

"We fully understand how our actions impacted everyone involved, with the level of media attention that events received, and understand that severe actions need to be taken in order to improve our community. We plan to move forward in a positive direction. .... I hope that the Michigan State Police, the university and the national organization of all the six chapters will hold all individuals accountable for their actions."

During the weekend, more than 200 members of Sigma Alpha Mu and Sigma Delta Tau booked about 40 rooms at Treetops Resorts in Gaylord and caused damages in excess of $100,000, including broken doors and furniture, holes in drywall, broken fixtures and soiled carpet.

Pi Kappa Alpha, Chi Psi, Delta Gamma and Alpha Phi rented 12 condo units at Boyne Highlands ski resort in Harbor Springs and caused more than $25,000 in damages to the units. Officials at the resort said the damage was similar to what the groups cause at Treetops.

Walsh said that each of the six organizations involved were sanctioned individually through the Greek Activity Review Panel while further sanctions were being considered by the dean of students, and all organizations were also punished to some extent by their national organizations.

The Greek Activity Review Panel board was made up of five justices from all four of the Greek councils.

"We worked in collaboration with the Center for Campus Involvement through the Student Organizations Accountability Review process. The justices have decided sanctions for each of the six organizations, and they are currently in the process of being approved by the dean of students," Walsh said.

"While I cannot speak to the exact sanctions, I would expect that punitive measures would be the most effective if paired with restorative and educational measures as well."

The dean of students Laura Blake Jones was involved in a closed-door meeting with university officials last week inside the Michigan Union examining the proposed sanctions and discussing other possible penalties for the organizations involved.

Beyond the six Greek organizations involved, Walsh said, leaders across the Greek community have come together to discuss how the the community can move forward.

"That being said, the student judicial process is only one element of self-governance. We recognize the importance of working collaborative with partners across campus and of the broader community. I would like to reassure you that students are taking this seriously, reflecting on their actions and looking towards a positive future," she said.

U-M spokesman Rick Fitzgerald said that the university could take actions as severe as suspending the Greek organizations, but issuing sanctions against individuals right now would be hard since they don't know which individuals were responsible for the actions. He said the judicial process and the university and the legal process with the MSP are ongoing.

"In the Greek community, we believe in restorative, not only punitive punishments. However, in this instance, punitive measures are also called for and have been included in these proceedings," Krupiak said.

"The only way to move forward completely from this is to make sure every member understands the consequences of his or her behavior. We also recognize that regardless of if an individual caused damage or not, each member had a responsibility to be an active bystander and failure to do so caused major ramifications for their organizations and the university as a whole.

"For the future betterment of the community, and hopefully for the betterment of the university as well, we pledge to help these chapters to continue to move forward in a positive direction. We will be working with each chapter very closely to make sure that they follow through with the sanctions, as well as make sure that the culture or each group is continuing to improve."

U-M Regent Denise Illitch was forgiving of the fraternities and sororities.

"I just want to thank you for coming forward. I accept your apology on behalf of the entire Greek community, of which I am a member and a University of Michigan alumni of the Greek community," she said.

Illitch asked Krupiak what the Greek community planned on doing to ensure something like this doesn't happen in the future.

"I think any sort of measure suggested in these hearings were a lot of educational measures, as well as just the whole community seeing these reports and realizing the ramifications," he said.

"I think one of the craziest things for myself and many of the members is how one member of one organization not only affects their chapter and the Greek community, but as a whole the University of Michigan and all of its alumni and every student here. So I think the realization of that, along with a lot of different educational measures across the spectrum will help immensely."

He said the parties fully plan on paying for all damages, but the cases hadn't been closed in the judicial process, so he couldn't speak in-depth about everything.

"I can assure you that all six chapters will be paying in full. The hearings have not been completed yet. Once the hearings have been completed, the sanctions will be placed upon all six chapters. The suggestions in the hearing were pretty severe and we hope we'll move into a positive direction with educational measures and suspensions as well."

Earlier in the meeting, U-M President Mark Schlissel said that the destruction and the vandalism that took place do not reflect the values of the university. He added that these actions were also not representative of the entirety of the student body or of the broad majority of students who participate in Greek life.

"The process is ongoing, but we intend to hold those who are responsible accountable for their actions," Schlissel said.

Walsh echoed Krupiak's apologies as well as Schlissel's statements. She said the actions from that weekend were not congruent with the values of the Greek community, and that they have taken steps to ensure the behaviors displayed are addressed.

"Beyond negative attention, the events of the weekend caused significant damage to the resorts and greater communities in northern Michigan," she said.

"I regret that members of the PanHellenic community have brought such vast media to the university and damaged the reputation we all strive to uphold as the leaders and best."
