Questions:1. How did the investigators conclude that the suspect was indeed the murderer? 2. What if a strand of hair was found in the truck bed instead of a seed pod, do you think it will still lead to the identification of the suspect?3. What do you think are the other uses of DNA fingerprinting?4. Why do you think the discovery of the seed pods provided the most crucial clue?5. What were the clues that led to the identification of the suspect?6. What if the strand of hair belonged to the victim, what other clues would you look for? The Case of the Telltale Palo VerdeOn the night of May 2, 1992, a woman from Phoenix, Arizona, U.S.A. wasstrangled and her body was dumped near an abandoned factory in the surroundingdesert. Police discovered a pager near the body, making its owner the prime suspect inthe murder. When questioned, the man admitted being with the woman on the day ofthe murder, but claimed he had never been near the factory. He suggested that thewoman must have stolen his pager from his pickup truck. A search of the pickup truckprovided the crucial clue. It placed the suspect in the factory. On the truck bed weretwo seeds from a palo verde tree.The palo verde tree is an unusual plant native to the desert of the Southwest. Amember of the bean family, it develops into a small shrubby tree. Well-adapted to thehot, dry climate, it has very small leaves. To compensate for this, its stems becomegreen and carry out food production. This adaptation gives the plant its name-paloverde, which is Spanish for "green stem." The plant may not resemble beans in somerespects, but like a typical bean, it produces seeds in pods that mature and drop to theground.The homicide investigators assigned to the case asked themselves the followingquestion: Could it be proven that the seed pods found in the bed of the suspect's truckhad fallen from one of the palo verde trees close to where the body was found? If so,it would be a key piece of evidence, placing the suspect at the crime scene anddestroying his alibi. But how could this be demonstrated? The investigators turned toDr. Timothy Helentjaris, then at the University of Arizona, in nearby Tucson.Helentjaris proceeded to determine whether the DNA fingerprint of the seed podsfrom the pickup truck matched that of one of the palo verde trees at the crime scene.Helentjaris knew that to make the match between a seed pod and a tree significant, hewould first have to demonstrate that palo verdes show genetic variation from one treeto another. Otherwise, it would be impossible to clearly link a given pod to oneparticular tree. Fortunately, he found considerable differences in DNA fingerprintsbetween individual plants.Helentjaris was then given the two seed pods from the suspect's truck along withpods collected by investigators from 12 palo verde trees present in the general vicinityof the factory. The investigators knew which of the 12 trees was the key one at thecrime scene, but did not tell Helentjaris. He extracted DNA from seeds taken fromcach and performed PCR on each sample. The results of this "blind" experiment wereunmistakable. The pattern from one of the pods found in the truck exactly matched thepatterns from only one of the 12 trees, the one nearest the body.Helentjaris" analysis was admitted as evidence in the trial, the first time the DNAfingerprint of a plant had been used in a court case. This information was critical inplacing the suspect at the crime scene. At the completion of the five-week trial, thesuspect was found guilty of first-degree murder. His conviction was upheld uponappeal, and he is currently serving a life sentence without parole.
