2 Preventing military rape "Preventing the crime of sexual assault remains our focus." United States Secretary of Defense Chuck Hagel

3 DNA database deterrent? Evidence Genotype database Rape kit Reference Genotype database Military personnel Upload Match Upload

4 Rape: DNA mixture evidence + +

5 Problem: human thresholds Threshold Under threshold, don't use alleles Simplify data for human review Allele Pair 7, 7 7, 10 7, 12 7, 14 10, 10 10, 12 10, 14 12, 12 12, 14 14, 14

6 Mixture database problem Evidence Allele database Reference Allele database + Rape kit Military personnel Upload Match Upload

7 TrueAllele ® Technology ViewStation User Client Database Server Interpret/Match Expansion Visual User Interface VUIer™ Software Parallel Processing Computers

8 TrueAllele interprets mixtures Separates mixture data into minor & major contributors 25%75%

9 Solution: genotype probability Use all data for computer analysis Explain the peak pattern Victim's allele pair Another person's allele pair Allele Pair 7, 7 7, 10 7, 12 7, 14 5%10, 10 90%10, 12 5%10, 14 12, 12 12, 14 14, 14

10 TrueAllele solves rape cases TrueAllele computer, over quadrillion Lab’s human review, under a million (Billion-fold loss of information)

11 TrueAllele in criminal trials Court testimony: state federal military international About 200 case reports filed on DNA evidence Crimes: armed robbery child abduction child molestation murder rape terrorism weapons

13 TrueAllele preserves information billion TrueAllele

14 Human thresholds lose information billion Thresholds TrueAllele

15 TrueAllele mixture database Evidence Genotype database Reference Genotype database + Rape kit Military personnel Upload Match Upload

16 World Trade Center attack September 11, 2001 in New York City, USA Over 2,700 victims

17 WTC TrueAllele database victim remainsmissing people match

18 1. Collect DNA from all military Reference Genotype database Military personnel Upload

19 2. Collect DNA from all rapes + Rape kit rape crime must be reported rape kit must be collected but attacker need not be named

20 3. Rapidly process rape kits + Rape kit

21 4. Accurately interpret DNA + Genotype probability 7, 7 7, 10 7, 12 7, 14 5%10, 10 90%10, 12 5%10, 14 12, 12 12, 14 14, 14 Rape kit

22 5. Upload to genotype database Evidence Genotype database Upload + Rape kit

23 6. Automated DNA comparison Evidence Genotype database Reference Genotype database Match + Rape kit

24 7. Identify and prosecute Evidence Genotype database Reference Genotype database The rapist Identify + Rape kit

25 Prevent rape by DNA monitoring Monitoring helps prevent people from behaving badly. TrueAllele computing for genetic surveillance to deter rape in the military.
