Episode 5: Planted Evidence
October 24, 1996 • 23 min
Single mother Denise Johnson is found dead in a deserted area outside of Phoenix, Arizona. Local investigators ask a molecular geneticist to pick out a tree in a 'lineup' when unidentified seed pods are found in suspect Mark Bogan's truck. The judge rules into evidence DNA profiles linking the pods to a tree near where the body was found. This is the first U.S. case where plant DNA was used to convict a criminal.
