s conviction  rests on the kind of testimony that is now barred from use in Texas courtrooms. 

 The new science around memory tells us that the initial tests of an eyewitness's memory are the only reliable ones - not the tainted testimony of a witness who has been hypnotized and makes an identification 13 months after a crime has occurred in this case,  Sween said in a statement.

 For too long, the Texas Court of Criminal Appeals has imposed arbitrary, unexplained barriers, denying death-sentenced prisoners with credible innocence claims, like Charles Flores, a chance to even get inside a courthouse to present their evidence of innocence before being executed,  she said.

Sween said she will continue to  pursue every available means to prove Mr. Flores's innocence. 

 All he wants is a fair trial untainted by patently unreliable testimony and official misconduct,  she said.
