The Potential of Forensic Genetics in
Resolving the Fate of the Missing
What are the technical tools needed?• Discovery
– Information systems
– Social Media
– Remote Imaging
– Geophysics
– Physical probing
• Recovery– Scene of Crime Documentation
– Forensic Archaeology
– Specialized Search and Recovery Teams; Canine, Diving, etc…
• Identification– Pathology, Fingerprint, Dental, Medical, Anthropology, DNA
– Systems for collection of AM data
– Databases and informatics for storage and comparison• Protection of Sensitive Data
Additional Hallmarks, Key Considerations
• In many incidents, response is conducted within a rule of law framework.– Response should be a responsibility of states.
– Terrorism• Criminal Investigations
– Recovery pattern, identifications, etc… pertain to both prosecutions and family relief
– War Crimes and Human Rights Violations• In addition to the “right to know the truth” we must consider
“right to justice” through effective investigation
– Requirement for high grade forensic analysis that can meet legal standards in a variety of applications.
• Adequate data protection, consent and subjects’ control of personal data.
Science cannot act in a vacuum.
• Additional Requirements
• Predetermined Roles and Responsibilities– Medical Legal Authorities
– Government Ministries (Justice, Human Rights, Foreign, Health)
– Law Enforcement
– Emergency Responders
– International Mechanisms• Criminal Tribunals
• INTERPOL
• Public Involvement and Outreach• Communication
• Trust
• Source of necessary information or genetic samples

More than technical capacity for particular forensic
disciplines, these issues often pose the greatest
challenge for an effective response.
A Rule of Law Requirement
An Emerging Human Rights Framework
• Affected Populations are entitled to victim identification efforts:
� Ending uncertainty: The right to know;
� Enable closure: The right to commemorate;
� Bring justice: The right to restoration and retribution;
� Restore public order: The right to rights.
• Victim identification goes beyond “humanitarian” concerns and invokes the rule of law, and increasingly formally recognized rights of human-kind.
United Nations Human Rights Council
• The UNHRC has stated the International Community must:
“…endeavor to recognize the right of victims of gross violations of human rights, and their families, and society as a whole to know the truth to the fullest extent practicable.”
• UN International Convention for the Protection of All Persons from Enforced Disappearance: the right to truth.
European Convention on Human
Rights and Fundamental
Freedoms
1. Article 2, Right to life.
2. Article 3, Right not to be tortured.
3. Article 5, Right to liberty and security.
Lack of “Effective investigation” has been ruled as a violation of Article 2 and 3.
Forensic DNA is an essential tool for meetingthis responsibility.
United Nations General Assembly
Resolution 61/155: Missing Persons
United Nations General Assembly
Resolution 61/155: Missing Persons
DNA is an essential tool for
Right to Know
Requirement for Identification
Requirement for Data Protection
United Nations Human Rights Council Resolution 10-26:
Forensic Genetics and Human Rights
• Recognizing… that forensic genetics, when applied in an independent manner and subject to international standards, may effectively contribute to the identification of the remain of victims
• The utmost respect for the principles of protection and confidentiality of information and restricted access to such information….
Need to Ensure Protection of Family Genetic Data
ICMP International Declaration“Declaration On The Role Of The State In Addressing
The Issue Of Persons Missing As A Consequence Of
Armed Conflict And Human Rights Abuses”
International Commission on Missing Persons – ICMP
•1995 Dayton Peace Accord;•~35,000 missing at end of conflict. •1996 Search for the missing begins.•June 1996 - ICMP was created following the G-7 Summit in Lyon, France•2003: Expanded Global Mandate
• -Post conflict, other regions
• -DVI globally
ICMP Mission
• To ensure the cooperation of governments and others in
addressing the issue of missing persons, including provisions
to build institutional capacity, encourage public involvement
and address the needs of justice.
• To provide technical assistance in locating, recovering and
identifying missing persons.
UN Safe Area Srebrenica•Safe Area Established 1993•July 1995, > 20,000 Refugees near UN DutchBat Compound •July 11, 1995: Over-run by Bosnian Serb Forces•NATO forces failed to defend.
July 11-13, 1995•Column of ~10,000-15,000 men •Attempt overland escape to Tuzla.•Attacked en route. Many killed, butthousands surrendered, taken prisoner.

ICMP Mortuary Facilities
Clothing and Personal Effects
A ‘Book of Belongings’, a joint effort
between the ICMP and ICRC, is shown
regularly to relatives of the missing,
and may provide a ‘presumptive
identification’
DNA Testing of “traditional methods”� ICRC Book of Missing shown to families: Clothing and personal
effects.
– 800 discrete cases from Srebrenica
� Families “identified” 281 cases.
– 72 cases where same effects identified by different families.
� Antemortem and postmortem comparison by experienced ICMP anthropologists/pathologists indicated 56 reasonable “presumptive identifications”.
– Information was “consistent” with identification.
� Subsequent DNA testing were exclusions for 25 of the 56 presumptive identifications.
ICMP Adoption of a ‘DNA-led’ Approach
New concept for mass graves identification efforts
● DNA previously regarded as a tool to confirm
presumptive hypotheses of identity established
through traditional means
Large scale typing and ‘cold hit’matching between
family reference profiles and victim profiles
Testing
● High statistical strength matches then checked
against all evidence in the case, to finalize the case.

• The Branjevo Farm assemblage has the most number of bodies, 1725. All of the
secondary graves are along the Cancari road, a rural area 6 to 11 kilometers from the
main road.

• Note the “chain” pattern of linkages from secondary graves back to primary.

What do missing persons need from
MPS?
• Ability to handle very degraded samples.
• Strong capabilities of kinship analysis.– Single, distant relatives?
• Vastly diminished costs.– Multiplexing
– Optimization and Streamlining
– Homogeneous Assays, Robust Pipelines
• Informatics that interfaces with other necessary data– Matching and case management in an integrated
identification system.

With MPS the cost of DNA sequencing has
decreased by ~6 orders of magnitude.
Can we do something similar for the cost of
human identification testing?
