( CNN ) -- Former Vice President Al Gore will not face prosecution on an allegation of sexual assault from 2006 . The allegation , brought forth by Molly Hagerty , claims Gore sexually abused her during a professional massage at the Hotel Lucia in Portland on October 24 , 2006 . CNN policy is to not name the alleged victim in a sexual abuse case , unless the person has come forward publicly to the media . Hagerty told her story to the National Enquirer . The Portland Police Bureau did not recommend prosecution `` due to a lack of credible evidence , '' according to the Multnomah County district attorney 's office . `` After evaluating the materials submitted by PPB I have concluded that I agree with the assessment that a sustainable criminal case does not exist , '' Senior Deputy District Attorney Don Rees wrote in a memo Friday . `` Ms. Hagerty 's detailed statement ... is insufficient to support a criminal charge given other contradictory evidence , conflicting witness statements , credibility issues , lack of forensic evidence and denials by Mr . Gore . '' Gore 's office in Nashville , Tennessee , released a statement saying the former vice president was pleased with the finding . `` Mr. Gore unequivocally and emphatically denied this accusation when he first learned of its existence three years ago , '' the statement reads . `` He respects and appreciates the thorough and professional work of the Portland authorities and is pleased that this matter has now been resolved . '' An attorney for Hagerty did not immediately return a call for comment . According to the district attorney 's office , Portland police first became aware of the allegations in December 2006 , when Hagerty 's attorney said his client had been subjected to `` unwanted sexual contact '' by Gore . After a series of canceled meetings with investigators , Hagerty 's attorney told police the matter would be handled strictly as a civil case and no police complaint would be filed . After Hagerty 's allegations were published in the National Enquirer this summer , Portland police opened a full investigation , Rees wrote . Portland police submitted their findings to the district attorney 's office on Tuesday and did not recommend prosecution . The district attorney 's office noted several deficiencies in the case : . `` Ms. Hagerty , who has red hair , states she called Mr. Gore immediately following the alleged incident and told him to 'dream of redheaded women ' seemingly in contradiction to her assertions that she was terrified of Mr. Gore , '' Rees wrote . The DA 's office also said Hagerty did not provide medical records she claimed were related to the case , despite repeated requests . Rees also wrote that Hagerty failed a polygraph examination and was apparently paid by the National Enquirer for her story .
