2 Property Crime Study Materials • 25 property crime cases
• 91 evidence items • nonsuspect reference comparison Match information results • human: 6 CMPs reported • computer: 33 LRs reported

3 Efficacy and Reproducibility

4 Sensitivity and Specificity
Within-case sensitivity Between-case specificity

5 Evidence-to-evidence
Within-case sensitivity Between-case specificity

6 Preserving Identification Information

7 Solving Unsolved Cases

8 Complex Case • 30 evidence items • 6 known references
• genotype: 36 items • compare: 180 pairs
