During Misskelley's trial, Richard Ofshe, an expert on false confessions and police coercion, and Professor of Sociology at UC Berkeley, testified that the brief recording of Misskelley's interrogation was a "classic example" of police coercion.[28] Critics have also stated that Misskelley's various "confessions" were in many respects inconsistent with each other, as well as with the particulars of the crime scene and murder victims, including (for example) an "admission" that Misskelley watched Damien rape one of the boys.[29] Police had initially suspected that the victims had been raped because their anuses were dilated. However, there was no forensic evidence indicating that the murdered boys had been raped. Dilation of the anus is a normal post-mortem condition.[3]
