A lawyer for the woman who accused Florida State quarterback Jameis Winston of sexual assault asked Friday for Florida's attorney general to independently examine the rape investigation, claiming it was riddled with problems.

Attorney Patricia Carroll called on the attorney general to investigate the Tallahassee Police Department's handling of the case, saying that detectives failed to interview key witnesses and that DNA tests were unreliable and incomplete.

The problems with the investigation "are so significant and so multiple," Carroll said.

The lead detective got a search warrant for her client's cell phone and social media accounts but failed to do the same for Winston and his two companions immediately after the accusations were made, Carroll said.

"The bulk of the investigation was into the rape victim," she said. "I'm looking at an investigation of a rape victim, not a rape suspect."

Last week, Leon County State Attorney Willie Meggs said there was not enough evidence to win a conviction against the FSU quarterback and Heisman Trophy candidate, mostly because there were too many gaps in his accuser's story.

Tallahassee police have defended their handling of the case.

"The case is closed, and we continue to support Mr. Meggs as we have done throughout this process," David Northway, a spokesman for the Tallahassee Police Department, said Friday.

Winston, 19, has led the Seminoles to a No. 1 ranking and a shot at a national championship next month.
