  7. His teeth were mistakenly matched to a bite mark left on the victim • Krone spent 10 years in prison, including 2 on death row • In 2002, DNA evidence proved he did not kill the bartender

  8. How did the mistaken match occur? • Why does DNA evidence overrule the bite mark evidence?

  9. Bite mark evidence requires a dentist to compare the bite marks with impressions and come to a conclusion based on what they see • Though the dentist has forensic training and is considered an expert, interpretation hinges on the dentist’s opinion • DNA evidence is interpreted using proven mathematical formulas and statistics
