"She reiterated to Mr. Pacheco that it was cut and dry, the investigator had prepared a false report." Under the U.S. Supreme Court's 1973 Brady v Maryland decision, prosecutors have a duty to disclose evidence helpful to the accused, including the credibility of a witness. Hunt said Pacheco told her not to disclose anything to defense attorneys in the unidentified case. Pacheco said there was a system set up in 2006, when Trask was district attorney, to review possible Brady violations and she did not follow that policy, he said. Hunt said in her lawsuit she did not know at the time that the same investigator was the subject of similar allegations in a case that was under review by the FBI and the U.S. attorney's office.
