Background
BC Coroners Service
! Investigates all unnatural, sudden and unexpected, unexplained or unattended deaths
! The Coroner determines: the identity of the deceased; how, when, where and by what means the deceased died
! The death is then classified as natural, accidental, suicide, homicide or undetermined
! In 2011, the BC Coroners Service investigated 7828 deaths
BC Coroners Service
! How many suicides were there in 2011? A. <100 B. 101-200 C. 201-500 D. 501-600 E. >600

! The IDRU provides support and expertise in identification, disaster response, and business continuity planning.
! Actively investigates all historical unidentified human remains cases, dating as far back as the 1960’s.
! There are currently 186 active unidentified human remains cases that remain unresolved

! In 2010, the IDRU investigated 102 unidentified human remain (UHR) cases: ! 73 Archaeological or Non-Human ! 25 Identified ! 4 Remained unidentified
! Since 1950, 186 unidentified human remains cases are still unresolved

! A relational database management system that integrates 4 provincial databases into a centralized GIS database:
Enhanced Identification-GIS Model
DNA DB Dental DB MPUB DB
Identification-GIS-DB
FME
Arch DB

Technology Breakdown
1. FME pulls information from 4 different provincial databases into a centralized database
2. FME generates two master outputs: ! ESRI Geodatabase ! Google Earth KML
3. Enables spatial and tabular queries for case comparisons
How does the ID-GIS Model work?
! Generates leads on unsolved cases ! Provides instant exclusions on potential matches
using case descriptors ! Tracks previously excluded cases ! Enables one-to-many comparisons between
missing person (MP) cases and unidentified human remains (UHR) cases
Advantages
Key Descriptors
Key Descriptors Iden-fica-on
Spa-al: GPS, address, etc.
Temporal: LSA date, found date, etc.
Circumstan-al: Radiographs, clothing, etc.
Racial Affinity: Caucasoid, Mongoloid, etc.
Biological: Height, weight, age, etc.
Gene-c: Y-‐STR, mtDNA, nDNA, etc.
“Hikers will travel up to 18.3 km in a temperate mountainous area” – Koester
Example #1 – Missing Hiker
“Scavengers transport remains up to 3.2 km in forested areas” - Haglund
Example #2 – Found Cranium
The IDRU manages an identified partial human remains inventory in the ID-GIS database, which is used to compare against newly found unidentified human remains.
Example #3 – Found Mandible
