TALLAHASSEE, Fla. — No charges will be filed against Florida State quarterback Jameis Winston in a sex assault investigation, announced State Attorney Willie Meggs at a news conference this afternoon.

Meggs said Wednesday his office had “exhausted all investigative tools” since the case was handed over to his office in mid-November.

“We have learned as much as we can learn,” said Meggs, who announce his findings at a 2 p.m. news conference at the Leon County Courthouse.

The woman who accused Winston of sexual assault told police she was raped at an apartment after a night of drinking at a bar, according to a search warrant released hours before a prosecutor was to announce whether the Heisman Trophy contender should face charges.

The alleged assault took place about a year ago. The woman didn’t identify Winston, who is black, until about a month later.

She said she had no idea where the alleged assault took place.

The details of the alleged rape were contained in a search warrant for cell phone records, including text messages.

Winston’s attorney, Timothy Jansen, has suggested Winston had consensual sex with the accuser and he expected the prosecutor will exonerate his client.

“If he looked at evidence we did, we feel confident he will find that Mr. Winston did nothing wrong,” Jansen said.

Jansen plans to have Winston briefly address the media at 3:30 p.m.
