Denise Johnson - a 30-year-old single mother - is found murdered in the Arizona desert. Investigators find a pager at the scene that belongs to a trucker, but not much else in the way of evidence. When a detective decides to find out if the plants at the scene can be used as evidence, the case makes forensic science history. Hosts: Colleen O’Brien, Erica White. Audio Supervisor: Tommy O’Brien.
