Questions for Discussion: Forensic DNA Analysis
How was DNA evidence used to prove that Dr. Sam Sheppard did not murder his wife? Why wasn't this evidence used when the case first went to court? Why do you think the DQA1 test was chosen for DNA analysis in this case, instead of another, more powerful genetic test? If the blood trail left at the murder scene wasn't Marilyn's or Sam's, whose blood might it have been? If you were a juror on this trial, would you be convinced by the DNA evidence?
