Not sure if this has been raised somewhere else in this thread, but if prosecutor didn't disclose evidence, did the defense also not know about the evidence, considering it was the child of the accused. Is the balance of power in favor of prosecution? Also, now that the the accused in the case has been declared not guilty, will there be an investigation into who actually committed the murder?
