(TALLAHASSEE, Fla.) -- Florida State University quarterback Jameis Winston's alleged rape victim claimed she was struck in the head and couldn't recall everything that happened to her the night of the reported incident, according to newly released 911 tapes.
The woman's friend called 911 during the early morning hours of Dec. 7, 2012 and told a Florida State University police that the alleged victim was "very shaken up."
"She got hit? Does she know what she got hit with?" the dispatcher asked.
"No. She says she like kept blacking out, like she only remembers pieces. She keeps trying to tell me the story but it's very in pieces," the woman replied.
State Attorney Willie Meggs said last week that Winston, a Heisman Trophy hopeful, would not be charged with sexual battery because there was not enough evidence to win a conviction. Meggs also said there were too many gaps in his accuser's story.
Police said it took the alleged victim, whose name has not been released, a month to identify her accuser as Winston.
Also included in the public records released Wednesday were video recordings of recent police interviews with Winston's friends, who acknowledged that the star quarterback and his accuser had sex that night, but it was consensual.
Fellow FSU football players Ronald Darby and Chris Casher told police that they walked in on Winston and his accuser having sex.
"We walked into the room and the girl was like, 'What are you doing?'" Darby told police. "She was like, 'get out.' So, Chris was like 'My bad.'"
"Was there anything she said that made you think she didn't want to have sex?" an officer asked Darby, who insisted that what he saw seemed consensual.
Eyewitnesses say they told police Winston took the girl home a few minutes later and quickly returned to the apartment, according to the newly released documents.
Winston, 19, said last Saturday after a win over Duke that the sexual assault allegations taught him that he needs to be "more mature."
The undefeated Seminoles will play in the BCS National Championship game in Pasadena, Calif., on Jan. 6 against Auburn.
Winston will be in New York City this Saturday at the Heisman Trophy presentation. But Winston's accuser continues to insist she was raped.
On Friday, the day before the award presentation, her attorney says he'll hold a press conference to reveal more information and a statement from the accuser's family.
