The UVA Phi Kappa Psi chapter president said in a statement on Monday that they are considering suing Rolling Stone

The investigation will remain open in case Jackie breaks her silence or any other witnesses come forward

Police say Jackie refused to cooperate with the police investigation when the story came out

The story published last November is based on an account from a UVA student named Jackie - who has remained anonymous

Chief Timothy Longo said Monday that detectives could not confirm gang rape happened, or that frat brother who 'organized' the attack exists

Four months after a Rolling Stone article about an alleged gang rape at a University of Virginia fraternity ignited fury across the country, police have come out to refute the facts of the story.

On Monday, Charlottesville Police Chief Timothy Longo held a press conference to announce that his department have been unable to confirm the rape described in the article happened.

Moreover, they were never able to determine whether the fraternity brother who allegedly masterminded the assault - named by victim 'Jackie' as 'Haven Monahan' - ever existed.

Longo carefully shied away from outright calling Jackie's story false and said the investigation would only be suspended - and not fully closed - in case she decides to break her silence and cooperate or more witnesses come forward.

He said he could not conscionably close the investigation since the findings do not prove 'that something terrible didn't happen to Jackie'.

'All I can tell you is that there is no substantive basis to conclude that what was reported in that article happened,' he added.

Longo's findings were enough for the fraternity to threaten legal action against Rolling Stone for the article they now call 'defamatory'.

Following the conference on Monday, chapter President Stephen Scipione announced that the organization is 'exploring its legal options to address the extensive damaged caused by Rolling Stone.'

The article published last November tells the terrifying story of a date gone wrong.

Jackie told Rolling Stone journalist Sabrina Rubin Erdely that just a few weeks into her freshman year she was asked out on a date by an older student she worked at the pool with.

She said the September 28, 2012 get-together started with dinner at a local restaurant and then progressed back to her date's fraternity, Phi Kappa Psi (called Phi Psi), for a party.

From there, the account turns grim as Jackie describes the boy - identified as 'Drew' in the article - leading her upstairs where she is locked in a room with several other men who proceed to rape her for three hours in what appears to be an initiation ritual.

While the article sparked debate about the issue of campus sexual assault, facts of the story quickly came into question by Jackie's friends who encountered her later that night and those in the fraternity who stood by their claim that they didn't host a party that night.

Rolling Stone has since issued an apology for the story and has asked the Columbia School of Journalism to investigate how the writer's reporting failed. The magazine is expected to publish those findings on April 8, according to CNN.

At the press conference on Monday, Longo announced that his department had been unable to confirm a rape happened that night, that a Phi Psi brother named Haven or Drew ever existed, and nearly any of the other claims made by Jackie to police and in the article.

Before the press conference, Jackie's attorney declined to comment.

Longo says the university first learned of the attack in the spring of 2013, when Jackie had a meeting to discuss academic issues with Dean Nicole Eramo, which she then pinned on a traumatic event in September.

It wasn't until the next year, however, that police were informed of the alleged rape when a Charlottesville Police Detective Via was called to the university to meet with Jackie and Dean Eramo about another attack on campus.

Jackie claimed she had been harassed by a group of men on campus who flung a bottle at her, leaving her face battered.

The facts: The November 2014 Rolling Stone article ignited fury on the UVA campus and across the nation for Jackie's horrific account of gang rape at the Phi Kappa Psi fraternity (pictured above). However, most of the details of the story could not be verified by police - including the existence of her alleged attacked

This incident was also detailed in the Rolling Stone article, but two of the facts didn't line up for police.

The first was that Jackie said she called her mom after the attack, and phone records indicate she never dialed her mother's number. The other is that she claimed her roommate cleaned glass out of a wound on her face. Police interviewed her roommate who denied doing such a thing, saying the injury was more of an abrasion than blunt-force trauma.

UVA'S PHI KAPPA PSI CHAPTER MAY SUE ROLLING STONE FOR 'DEFAMATORY' ARTICLE Following the Monday police press conference, Phi Kappa Psi chapter president Stephen Scipione confirmed the organization is considering suing Rolling Stone over the 'defamatory' article. Scipione said Phi Psi is 'exploring its legal options to address the extensive damaged caused by Rolling Stone.' He added that the 'false accusations have been extremely damaging to our entire organization, but we can only begin to imagine the setback this must have dealt to survivors of sexual assault.' 'We hope that Rolling Stone’s actions do not discourage any survivors from coming forward to seek the justice they deserve. 'Following the publication of the defamatory article, the chapter launched an extensive internal investigation, which quickly confirmed that the horrific events described in the Rolling Stone article did not occur. 'Both the Virginia Alpha chapter and Phi Psi’s national organization adhere to a strict zero tolerance policy in regards to sexual assault.' Advertisement

Jackie allegedly told Detective Via about the September 2012 gang rape at a meeting about the bottle incident, but refused to go into details.

When the Rolling Stone article was published the following fall, and the police were called in to investigate, Detective Via remembered Jackie's name and reached out to her to talk. After dodging his call, Jackie responding a few days later with an email saying she would meet with police after Thanksgiving break.

She held up on her end of the deal, but when she arrived at the police department a few days later in December, she was accompanied by a lawyer who spoke on her behalf, saying she would not be cooperating with the investigation. When police tried to obtain university records pertaining to Jackie, she also refused to sign off.

As for her alleged attacker, Haven Monahan - police could not find evidence that he existed.

They checked the fraternity's roster for the time and found no record of a Haven or Drew (as he was named in the article), or other brothers matching the description in the article. They also interviewed nine of the 11 men who lived in the house at the time, as well as the current brothers, who stood together to deny witnessing any such incident.

Two of Jackie's friends say she talked about Haven, and that they exchanged text messages with him, but say they never actually met him in person.

Police searched phone records to try to connect the suspect to the phone used to text Haven but were unsuccessful.

Jackie's two friends also said the story in Rolling Stone differed greatly from their memories of the night they found her shaken after a date.

Police interviewed supervisors and former student workers at the school's pool, where Jackie says she met her attacker, and none remember a specific coworker that Jackie grew close too.

While there was one worker at the pool who was in a fraternity, it was not Phi Psi, and he said his shift patterns didn't overlap with Jackie's.

The members of that different fraternity also didn't recall an incident in September 2012, and the layout of their house on campus is 'very different' from the one recalled by Jackie to Rolling Stone, Longo said.

Phi Psi's social calendars show that they didn't have any party planned for the weekend. While that doesn't prove much considering the hard-partying college lifestyle, police did find that the fraternity's sister organization, the Delta Gamma sorority, hosted a formal that weekend, meaning many of the brothers would have been attending that.

Center of anger: The fraternity was suspended following the article, but later reinstated when university officials could not prove the incident happened. Above, the Phi Kappa Psi house gratified in the aftermath of the explosive article

STATEMENT FROM UVA PRESIDENT TERESA SULLIVAN On behalf of the University of Virginia, I would like to express my sincere appreciation to Chief Timothy Longo and the Charlottesville Police Department for their thorough investigation into the allegations described in the November 2014 article in Rolling Stone magazine. I would also like to thank the individuals who cooperated with the police investigation. The investigation confirms what federal privacy law prohibited the University from sharing last fall: that the University provided support and care to a student in need, including assistance in reporting potential criminal conduct to law enforcement. Chief Longo’s report underscores what I have known since well before the publication of the Rolling Stone article: that we at the University are committed to ensuring the health and safety of all of our students. We cannot fulfill our mission as an institution of higher learning without providing for the welfare of our students and our community. There is important work ahead as the University continues to implement substantive reforms to improve its culture, prevent violence and respond to incidents of violence when they occur. We will continue our collaborative partnership with the Charlottesville Police Department, united by our shared commitment to fostering a culture of respect while ensuring the safety and well-being of all members of our community.

Police also obtained a picture taken inside the fraternity on the night of the alleged attack, and it shows a man holding two chairs near the front door, with no one else around - differing from Rolling Stone article's account of the house being packed with revelers.

'There's no basis in fact that there was even an event that night,' Longo said.

In the article, Jackie said she finally decided to go public with her story because she met two other girls who said they too were gang-raped at the same fraternity, one in 2010 and one in 2014.

However, police are also weary of those accounts, since neither of those alleged victims has come forward.

Longo ended the press conference by stressing that anyone with information on the rape - or any other rape for that matter - come forward, the earlier the better.

'Having police involvement in the very early stages of these investigations is extremely, extremely important,' Longo said.

Following the press conference, UVA President Teresa Sullivan issued a statement thanking local police for their 'thorough investigation'.

'The investigation confirms what federal privacy law prohibited the University from sharing last fall: that the University provided support and care to a student in need, including assistance in reporting potential criminal conduct to law enforcement,' Sullivan said.

'Chief Longo’s report underscores what I have known since well before the publication of the Rolling Stone article: that we at the University are committed to ensuring the health and safety of all of our students,' Sullivan added.
