Sources: Winston probe complete

— -- TALLAHASSEE, Fla. -- The prosecutor looking into sexual assault allegations against  Florida State quarterback Jameis Winston has wrapped up his investigation and all tests have been done, sources close to the state attorney told ESPN's Shelley Smith on Wednesday.

There is no time frame yet for an announcement.

Winston, who was named the ACC player of the year Wednesday, has led the Seminoles to the No. 1 ranking and they will play for a conference title Saturday, with a shot at the national crown. The quarterback is also the leading candidate for the Heisman and many voters are waiting to see if Winston will be charged with a crime before casting their ballots. The deadline for Heisman ballots to be turned in is Dec. 9.

While the allegations were initially reported to Tallahassee police nearly a year ago, the case wasn't turned over to prosecutors until November. The Tallahassee Police Department has defended its handling of the case even though the family of the victim has said that police detectives warned them about pressing charges.

State Attorney Willie Meggs initially estimated it would only take a few weeks for prosecutors to determine whether to charge Winston. ESPN reported last month that DNA that matched Winston was found in the underwear of the accuser. While Jansen has suggested that the sex was consensual, the family of the accuser issued a statement alleging that Winston raped the woman.

Meggs has repeatedly said his office must not only present enough evidence to charge someone but determine whether there is a reasonable chance for conviction before proceeding.
