Residents of a Boston University dormitory woke up Monday to find a racist message about the Super Bowl scrawled on a door.

The message written on a whiteboard used an expletive, followed by a racial slur and an offensive comment about the Philadelphia Eagles and Donald Trump.

In a letter to residents of the 33 Harry Agganis Way building, Kenneth Elmore, dean of students and associate provost, described the message as vile and an attack on the BU community. It is, he said, antithetical to the school’s values. “This is unacceptable,” Elmore wrote, “and we are better than that.”

He wrote that police are investigating.

Colin Riley, a university spokesman, said an update was not available Tuesday afternoon.

The student body president, SaraAnn Kurkul, said, “I was beyond disappointed to learn of the vile, racist words written on one of my fellow peer’s dormitory whiteboard.” She said the student government and student body stand with the dean’s message that such behavior has no place on campus.

“I have confidence that our police department will find the person or individuals swiftly and that BU will hold them accountable,” Kurkul said. “My thoughts are with my fellow peer targeted by the hatred, and I hope they know Student Government stands behind them 100 percent.”

On Thursday, Elmore sent an update, telling the community the person responsible for the message had been identified. Elmore said a student had written the offensive message, and that the student had written a letter of apology, which the dean included with his email. Elmore’s note said, in part:

The Boston University Police have identified the person responsible for writing a vile, racially derogatory epithet on an 18th floor suite door within this residence. Disappointingly, the person responsible for this act is one of our students.

This behavior has consequences. I am following up with this student via the university’s disciplinary system. The Boston University Police Department is following up via available civil proceedings. As additional follow up, let’s not support or sanction this behavior from each other.

It saddens me that you had to deal with this.

The student’s apology letter read, in part:

“My heart is in shambles right now. . . . What I had done was disgusting, twisted, and sickening.”

He said the university prides itself on respect and diversity as cornerstones of its values, and said that while he was intoxicated and angry after the New England Patriots lost the game, that does not excuse what he did.

“In no way, shape, or form did I ever mean to offend or hurt anyone. I know that the words ‘sorry’ coming out from my mouth may not fix any damages I have already caused but I cannot stress how truly and deeply sorry I am for my actions, and I hope that people do not see me as that vulgar and racist person. That is not what I support, what I stand for, and most importantly who I am. Those words are not part of my daily vocabulary.

“I’m here today to tell you I’ve made a mistake and not just any mistake, but the biggest mistake of my entire life. I put my friends, family, and acquaintances into shame. I’ve let myself and my dignity down. And more importantly, I’ve let the Boston University community down.

“I can only hope for forgiveness and hope that people will believe that I can change and will never do such a thing ever again.”
