The prosecution presented a witness at the second trial to support the claim that the child witnessed the murder. That seems to completely contradict the assessment at the scene, where investigators saw no reason for her to be assessed by a professional for physical and psychological trauma. If she had been assessed by a professional, photographed, and processed for forensics, then there would no reason to rely on the observations of a daycare employee. In fact, we would also know whether the child had been cleaned at any time after the murder and before the discovery of the body.
