Dr Pornthip was also critical of police handling of the crime scene and improperly collecting evidence at the crime scene. Dr. Pornthip cited police failure to analyse the blood that was found at the crime scene. Dr. Pornthip also cited the moving of one victim's body from the place where she was killed, an action that could potentially destroy evidence.
