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.

secondary graves are along the Cancari road, a rural area 6 to 11 kilometers from the

main road.

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?
