The Forensic DNA Division started DNA identification services in 1991 for the first time in South Korea and has been
performing personal identification and confirmation of identity for various incidents and accidents.
It obtained accreditation from KOLAS International Accreditation Agency in 2004 for the first time in South Korea
and is recently teaching DNA identification techniques through the KOICA ODA project, etc. It has been internationally
recognized for solving the Seorae Village Infanticide Case in 2006 and played a leading role in identification of victims
of major disasters such as the Daegu Subway Fire, Sinking of the Sewol Ferry, etc.
Additionally, in accordance with the Act on the Protection and Support of Missing Children, etc. in 2005 and the Act on the Use and Protection of DNA Identification Information in 2010, the Forensic DNA Division has built a national DNA identification information database, and DNA quality control service for unresolved murder cases has been newly established as the statute of limitations for murder cases has been removed due to the amendment of the Criminal Procedure Act in 2015.
Furthermore, it carries out species identification and object identification of animals, plants, microorganisms, foods, etc. through DNA analysis and supports investigative agencies through “emergency analysis” for major violent cases.
DNA identification of crime scene evidence of violent cases (murder, robbery), sexual violence, theft, etc.
Identification through DNA analysis for persons accidently killed, missing persons, missing children, missing elderly with dementia, persons with mental retardation and independence patriots
Species identification and blood type analysis for non-human life forms such as animals, plants, microorganisms, etc.
Listing DNA identification information on crime site evidence and arrested suspects to the database and search according to the enforcement of the Act on Use and Protection of DNA Identification Information (July 26, 2010), quality control service

The Forensic DNA Division consists of a DNA Analysis Lab, Trace DNA Analysis Lab, Emergency Precise Analysis Lab, Arrested Suspect Analysis Lab, Search Target Analysis Lab, DNA Information Management Lab, DNA Quality Control Lab, Missing Child Analysis Lab, DNA Identification Lab, and Forensic Biology Lab. Moreover, a Smart Lab of this institute is in operation on Jeju.
The DNA Analysis Lab analyzes the DNA profile of human samples such as bloodstains, semen, saliva, hair and skin cells collected from crime scene evidence related to violent cases (murder, mutilation, robbery, sexual violence, etc.), narcotics offenders, traffic accidents, accidents, fraud, etc.
DNA profiling is carried out in trace amounts of evidence collected at the crime scene. In particular, the evidence collected at a theft site often contains trace amounts of contact evidence that is less visible than normal bloodstains or semen. After obtaining the DNA type from such a small amount of contact evidence, the laboratory detects the DNA type of the criminal and helps the police solve the case.
The Emergency Precise Analysis Lab conducts DNA profiling and research on evidence related to urgent violent cases, accidents and criminal investigations as well as precise analysis on evidence in unsolved cold cases. Additionally, it provides urgent analysis services on the evidence of violent cases (murder, rape, robbery, traffic accidents, etc.) for local institutes. The laboratory makes great contribution in criminal investigations and solving incidents and accidents with faster and accurate DNA analysis and profiling in close cooperation with the police.
The Arrested Suspect Analysis Lab compares the DNA database for unsolved cases through DNA analysis on the samples of suspects
arrested for 11 major crimes (murder, rape, juvenile sexual assault, robbery, arson, abduction, habitual violence, organized violence,
narcotics, special theft, murder of a ranked soldier under military criminal law, etc.) in accordance with the
『Act on Use and Protection of DNA Identification Information』 enacted on July 26, 2010. The DNA database for unsolved cases
is built with DNA data isolated from the evidence of numerous rape, theft, and murder scenes.
For personal information protection, the requesting agency encodes the personal information and assigns an identification code to the arrested suspect sample. The DNA analysis result for the arrested suspect is stored in the arrested suspect database with the identification code, and the remaining sample and DNA are immediately disposed.
The Search Target Analysis Lab performs DNA profiling and research of a search target requested by the police with regard to the crime scene DNA identification information.
The DNA Information Management Lab performs search and management of DNA identification information of crime site evidence and arrested suspects by establishing a DNA Identification Management System (DIMS) in accordance with the 『Act on Use and Protection of DNA Identification Information』.
The DNA Quality Control Lab performs quality control and research on DNA as well as manage remaining amounts of DNA used for current or past testing. Additionally, it operates the DNA identification database that rules out and performs DNA information analysis and research for the purpose of criminal investigation.
The Missing Child Analysis Lab caries out family identification through DNA search of missing children and their guardians by linking services with the "Missing Child Specialist Institution“ commissioned by the Ministry of Health and Welfare in accordance with the 「Act on the Protection and Support of Missing Children, etc. 」. * In accordance with the 「Welfare of Older Persons Act」 amended in 2012, the laboratory conducts a DNA-based Dementia Elderly Finding Project for missing elderly with dementia by linking services with the "Central Dementia Center" commissioned by the Ministry of Health and Welfare. It also carries out confirmation of the descendants of independence patriots requested by the 「DNA Analysis Project for Descendants of Independence Patriots, etc.」 and family identification through genetic testing of missing persons and their caregivers (bereaved family).
The DNA Identification Lab performs identification services for unidentified dead bodies and victims of major disasters. For old bones or corrupted bodies, nuclear DNA and mitochondrial DNA analyses are performed. The identification process is performed by the request of the family of the missing person, and if the identity is not confirmed, the case is managed in the database for unidentified dead bodies.
The Forensic Biology Lab performs analysis throughout forensic biology including species identification of non-human samples such as microorganisms, plants and animals and serological analysis on blood, bloodstains, tissues, etc.
The Jeju Smart Lab supports advanced security services of the police by the faster processing of DNA profiling for major emergency cases occurring in the Jeju area (search for the suspects of violent cases such as murder, robbery, violence, traffic accidents, etc. as well as sexual offenses) and establishment of an immediate response system to crime scenes.
