The lead prosecutor in the Patrick Kane rape investigation said Friday the mysterious evidence bag uncovered earlier this week that led to charges of evidence tampering in the high-profile case was an "elaborate hoax" orchestrated by the mother of the alleged victim.

According to the Chicago Tribune, Erie County District Attorney Frank Sedita III claims the bag was given to the accuser's mother when she accompanied her daughter to a local hospital to have a rape kit done Aug. 2, and she was the last known person to have the bag. In addition, he claimed video recordings show the actual kit administered was put in a box and never placed in a bag.

The accuser's attorney came forward earlier in the week to report the mother claimed to have discovered the bag mysteriously left at her doorstep. Thomas Eoannou has since resigned from the case and admitted he no longer believes the story told to him and others by his former client's mother.  

"The evidence in the case wasn't tampered with nor was it compromised," Sedita said. He added all the drama shouldn't affect the ongoing criminal probe, unless it is determined the accuser actually participated in the scheme.

The 21-year-old woman claims on the night in question she and a friend partied with Kane at a downtown sports bar in his hometown Buffalo and later in the night went back to his lakefront residence to continue the celebration.

While there, the still unidentified woman told authorities Kane overpowered and attacked her. But earlier this month, several media outlets reported none of the DNA evidence thus far retrieved in the case matched that of Kane.

"They tried to undermine the science in the case," Kane's attorney Paul Cambria said of the evidence bag hoax. "That speaks volumes about the credibility of the (rape) allegation."

In addition, multiple sources are also reported to have told the Tribune the female friend no longer fully supports the accuser's version of events and has expressed growing reluctance to testify on her behalf.
