Reading the background on Wiki, it sounds as if the prosecutor was the dishonest one and found a forensic pathologist from Oklahoma to testify, based on her false evidence. The state's own forensic pathologist was not called to testify (her analysis showed none of the six matched body fluids from the victim).
The false confessions were obtained with the threat of the death penalty.
Correct, I actually worked with 2 of the people involved when I worked at the Sheriff’s office on 05 to 07. Dr. Price and Deputy Sandersfeld. We were not allowed to even discuss the subject amongst coworkers.
