1 Forensic Stasis in a World of Flux
Quattrone Center Spring Symposium Technology in Criminal Justice Reform May, 2016 Philadelphia, PA Mark W Perlin, PhD, MD, PhD Cybergenetics, Pittsburgh, PA Cybergenetics © Cybergenetics ©

2 Pinkins confined 1989 – 5 men raped an Indiana woman
Darryl Pinkins and 2 others misidentified 1991 – wrongfully convicted, 65 year sentence 2001 – DNA mixture evidence 2 contributors found, not the accused but 5 were needed, post-conviction relief denied

3 Complex data • DNA mixtures • small amounts • degraded DNA

4 Simple solution (1) Simplify data (2) Peek at answer (3)
Calculate statistic • Put people in the process • To overcome software failure • And introduce human bias

5 Information failure MIX05 (2) – inconclusive, 4-14 zeros
MIX13 (3) – 70 of 100 labs falsely include CPI statistic – random number, shutters labs • inclusion, subjective with wrong statistic • exclusion, subjective with no statistic • inconclusive, discard probative evidence

6 Forces of stasis • human need for certainty
• fear of cross examination • self-regulating hall of mirrors • government forensic monopoly • software limitations reduce work • some lawyers fight against truth • state liability for DNA abuse

7 TrueAllele resolution
Capability Human-centered Computer-driven Data Choose Must use all Uncertainty Threshold Probability Neutral Include only Include/Exclude Statistic Random number Probative value Transparent Black box Math disclosed Testable Inner mind Available software Objective No Not given answer Validated 31 (7) studies Accurate Empirically proven Automated Unlimited capacity Frye/Daubert 7 states Item-to-item Connect scenes Cybergenetics ©

8 Pinkins released April 25, 2016

9 TrueAllele exoneration
1. compared evidence with evidence 2. calculated exclusionary match statistics 3. revealed 5% minor mixture contributor 4. jointly analyzed DNA mixture data 5. showed three perpetrators were brothers found 5 unidentified genotypes, defendants not linked to the crime

10 Forces of flux • respecting DNA evidence • accurate computer modeling
• eliminating human bias • accepting variation in nature • empirical software testing • some lawyers fight for truth • state liability for DNA abuse

11 Fruits of bad forensic science
DNA injustice Fruits of bad forensic science False convictions innocent imprisoned False acquittals guilty go free Unnecessary victimization people harmed

12 TrueAllele can reopen the past by automatically re-examining DNA data
Catalyzing justice “inconclusive” often means failed evidence interpretation State fails to disclose potentially exculpatory DNA Falsely convicted, civil rights violation Tried & acquitted, malicious prosecution Unnecessarily victimized, state liability TrueAllele can reopen the past by automatically re-examining DNA data
