The manslaughter claim undermined Kiszko's claims that he was totally innocent and destroyed his alibis (a defence known in legal parlance as 'riding two horses'). In fact, his innocence could have been demonstrated at the trial. The pathologist who examined Molseed's clothes found traces of sperm, whereas the sample taken from Kiszko by the police contained no sperm. There was medical evidence that Kiszko had broken his ankle some months before the murder and, in view of that and his being overweight, he would have found it difficult to scale the slope to the murder spot. The sperm findings were suppressed by the police and never disclosed to the defence team or the jury; neither was the medical evidence of his broken ankle disclosed to the court.
