You were right about this, bjs1779. I understand there are pre- or post-mortem tests so sophisticated they can detect signs of strangulation in soft tissues, even 14 years later. Dr. Thogmartin blundered by releasing the body for cremation in a case "of criminal importance." The body may well have contained clues.
Remember when he said it was a "classic case of sickle cell trait" AFTER the video of Martin Anderson was released? I don't think there is much doubt that he would've allowed his body to cremated, video or no video. The list of irregularities is rather long.
