Rolling Stone magazine has backtracked on the major University of Virginia gang rape story it published last month. The report did not include any interviews with the alleged victim in the case and the magazine’s managing editor said that their trust in her was “misplaced.”

Journalist Sabrina Rubin Erdely’s story was published on Nov. 19 and in it, a woman named Jackie claimed that she was gang raped. Jackie said that she was attacked at the Phi Kappa Psi fraternity house in fall 2012. The story noted that sexual assaults at UVA often go unreported and the university scrambled to start an investigation after it was published.

However, as USA Today points out, media critics noticed a few holes in the story, including no quotes from the men Jackie claimed attacked her.

In today’s open letter to readers, managing editor Will Dana wrote that Erdely made a deal with Jackie to not contact any of her alleged attackers. Since Jackie had told her friends and rape activists about the attack, and was open about it in campus forums, no red flags went off among the Rolling Stone editors or fact checkers.

“In the months Erdely spent reporting the story, Jackie neither said nor did anything that made Erdely, or Rolling Stone's editors and fact-checkers, question Jackie's credibility,” Dana wrote.

Dana concluded that, “In the face of new information, there now appear to be discrepancies in Jackie's account, and we have come to the conclusion that our trust in her was misplaced. We were trying to be sensitive to the unfair shame and humiliation many women feel after a sexual assault and now regret the decision to not contact the alleged assaulters to get their account. We are taking this seriously and apologize to anyone who was affected by the story.”

The UVA chapter of Phi Kappa Psi said in a statement Friday that they had “no knowledge of these alleged acts being committed at our house or by our members.”

There were two other major holes in Jackie’s story. Erdely’s story said that one of the alleged attackers, Drew, was a lifeguard in fall 2012. However, the aquatic center had no record of anyone by that name working there at the time.

In addition, Jackie said that the attack took place during the fourth weekend of the school year. But the fraternity didn’t have any social events scheduled at that time.
