HANOVER, N.H. — Things have only gotten messier at Dartmouth College in the weeks since a former fraternity brother went public with hazing allegations involving swimming in and swallowing vomit.
Senior Andrew Lohse brought the issue to the forefront in January, when he wrote a column in the school newspaper describing "dehumanizing" experiences he witnessed at Sigma Alpha Epsilon.
According to Mr. Lohse, the fraternity pressured pledges to swim in a kiddie pool of rotten food, vomit and other bodily fluids, eat omelets made of vomit, and chug cups of vinegar. He called those activities the norm rather than the exception on the Ivy League campus, and he criticized the administration for not doing enough when he made anonymous complaints last year.
The week after the column was published, more than 100 faculty members wrote to the administration, describing hazing as an "open secret" and calling on the administration to set up an independent commission to address it. The college has since formed a task force and brought hazing charges through its judicial affairs office against the fraternity and more than a quarter of its members, including Mr. Lohse.
Dean of the College Charlotte Johnson declined to comment on those charges, but the fraternity's president, Brendan Mahoney, said all 27 accused students face identical charges relating to new member recruitment in the fall of 2011.
But by that time, the fraternity had gotten rid of any traditions that would be "deemed problematic" by the administration, Mr. Mahoney said, and no current members of Sigma Alpha Epsilon were members in 2009 when Mr. Lohse was a pledge.
As for Mr. Lohse's graphic allegations, "None of these practices, and nothing remotely close to hazing, occurred at our pledge events in 2011," he wrote in an email to the Associated Press.
Mr. Lohse did not specify in his column whether all alleged abuses occurred in 2009 or later, and he declined to comment Monday, citing an agreement with another publication.
DartBlog.com, a blog written by former students about the college, obtained a copy of the letter notifying Mr. Lohse of the charges against him.
According to the letter, Mr. Lohse is accused of threatening physical harm to new fraternity members, putting other students in fear for their safety and/or engaging in hazing during the fall 2011 term. He also is accused providing alcohol to underage students, providing drugs and/or providing alcohol to obviously intoxicated individuals during the same time period.
The charges filed were identical for the other individuals, "even though Lohse's tale does not describe them as engaged in the same activities," said Mr. Mahoney, who said students have been charged "without a shred of real evidence." Administrators, he suggested, are panicking in the face of bad press.
"We do know that Dartmouth has come in for a lot of bad publicity because of Lohse's allegations. We hope Dartmouth's administration will focus on the evidence rather than on a public relations strategy," he said.
Ms. Johnson, the college administrator, strongly denied both Mr. Lohse's accusation that the college failed to act on his initial complaints and Mr. Mahoney's suggestion that the recent charges were brought to quell criticism.
"When we get detailed, specific information regarding hazing or any other violation of our code, we act," she said. "This isn't a witch hunt, nor are we sitting on our hands."
