The woman who accused Florida State University star Jameis Winston of raping her has come forward for a new documentary that premiered Friday at the Sundance Film Festival. Erica Kinsman, 20, speaks publicly in the film for the first time, claiming she came to after drinking at a bar to find Winston on top of her having sex in his apartment while she pleaded with him to stop. In the film, Kinsman says one of Winston's roommates also allegedly begged him to stop before the quarterback took her into the bathroom and pinned her head to the floor to continue the assault. The Daily Beast reports that Kinsman is featured in Kirby Dick's documentary The Hunting Ground, which casts a critical eye on the role that fraternities, athletic departments and schools play in rape investigations on campus. Kinsman fights tears as she details her account of the December 2012 night, when as a freshman, she remembers running into a man at a Tallahassee Potbelly's. She says someone was creepily following her around the bar throughout the night and only stopped when a second man put his arm around her and told her pursuer he was her boyfriend. Kinsman says that man then bought her a shot, after which she began to feel dizzy, though she faintly recalls taking a cab to an apartment. She says the next thing she remembers is coming to while the man on top of her penetrating her, and claims that she asked him to stop. The man allegedly ignored both her and his roommate, who Kinsman says entered the room and told him to stop, and took her into the bathroom. There, she says, he raped her while he held her head against the tiles, and when he was finished told her 'You can leave now.' Not knowing where the apartment was, Kinsman says she took an offer for a ride on the man's scooter back to a location she recognized, fearing what would happen if he knew where she lived. According to a New York Times investigation of the ensuing police investigation, Kinsman reported the assault in the early morning immediately after it happened, but did not identify the assailant. Tallahassee Police Officer Scott Angulo wrote he 'had no real leads' until Kinsman contacted police a month later, saying she saw the man in class and heard his name called, identifying him as Winston. Dick, who also directed The Invisible War, about a lack of accountability when prosecuting sexual assault in the US military, rips into the investigation in The Hunting Ground. The film asserts Angulo, an FSU grad who had worked for the Seminole Boosters, not only failed to identify Winston, but did not obtain DNA evidence, cell phone records or interviews with witnesses. KIRBY DICK'S DIRT-DIGGING DOCS The Arizona-born documentary filmmaker has tackled America's attitude toward sex and sexuality and taken aim at powerful institutions like the Catholic Church and the US military. The 2004 film Twist of Faith depicts a man suing the parish where a priest sexually abused him as a child - and the heartbreaking reactions of his friends and family. Outrage, released in 2009, asserted closeted gay politicians help drive lobbying for anti-gay legislation. He caused a shake-up in the way the US military handled cases of sexual assault after his 2012 film The Invisible War exposed the armed services' failures to hold rapists in their ranks accountable. The officer also allegedly failed to get recordings from Potbelly's 30 security cameras or get a cell phone video Winston's roommate, football player Chris Casher, later admitted to recording of the sexual act. By the time State Attorney William Meggs took over the investigation, nine months after Tallahassee police closed it, the tapes had been recycled and the cell phone video deleted, according to the film. Meggs eventually wrapped up the investigation in December 2013 with no charges filed, though DNA on Kinsman's shorts matched that of Winston. 'I think things that happened that night were not good,' Meggs says in The Hunting Ground, though there was insufficient evidence to support criminal charges. A FOX Sports investigation reported in October that Tallahassee police helped FSU officials stay ahead of any prosecution by the state attorney. The university's chief of police received original and supplemental reports four days before the case was handed off to Meggs, according to documents obtained. These reports were then forwarded to an FSU athletics department official, who provided them to Winston's defense attorney before the case was passed to prosecutors, the investigation found. Two witnesses, football players who watched Winston engaging in a sexual act with Kinsman, spoke to Winston's lawyer and were convinced to sign affidavits in support of Winston's account of the night - before police ever interviewed them.
