Now, a letter has surfaced saying the Alpha Xi Delta formal held on March 26 at the National Underground Railroad Freedom Center.
President David C. Hodge of Miami University said in a letter to the Miami community that, "property was damaged, alcohol was consumed and those in attendance acted in a disruptive, disrespectful and destructive manner."
"It's deeply embarrassing to us and appalling to be honest," said David C. Hodge, President of Miami. "We're distressed at all of those things. The Freedom Center most egregious and appalling to us. It's not that things were done with intentions, but the lack of sensitivity to the place that they were at goes against everything that we stand for."
President Hodge says he called the Freedom Center to apologize as soon as he learned of the incident, and also says the university's office of ethics and student conflict resolution has recommended a two-year suspension for Alpha Xi Delta.
"It sends multiple messages," he said. "First, that kind of behavior is not to be tolerated, but secondly it holds the whole group accountable for the actions of some and that gets back to the bystander notion. It is a sorority and fraternity. It is a group of people that are bound together and they must be accountable..for each other."
Alpha Xi Delta is appealing their suspension while Pi Beta Phi has not challenged it's one year ban from Miami's campus.
The Freedom Center did not want to talk on camera about the incident, but they have invited the sorority back in the fall for a tour and discussion.
In a statement, Indianapolis-based Alpha Xi said it was "saddened by the inappropriate behavior" and apologizes to the Freedom Center.
"The poor judgment and actions that some individuals displayed showed not only little respect for the facility but for themselves," the statement said.
