Yes, Klaas particiipated in a press conference on behalf of another family whose daughter was molested in another case Mckowan was supposed to be prosecuting. The family filed a lawsuit because they said Mckowan lied to a judge to get out of trying the case by saying the family didn't want the daughter to testify. Bizarrely, according to the family, Mckowan got the case delayed for two years. Just two days before the trial, Mckowan told the family that she hadn't lined up any witnesses and asked them if they could PAY to fly out a witness for the prosecution.
The family is continuing with their lawsuit. At a recent hearing, a judge stated to their lawyer that they did have standing to complain that Mckowan and the San Mateo DA's office perpetrated fraud.
