In 2025, Thailand is actively expanding its national DNA database to combat serious crime. The project, led by the Central Institute of Forensic Science (CIFS) with support from the Ministry of Justice and international partners, has become a key tool in solving murders, rapes, human trafficking, and terrorism.
Today, the CIFS database contains over 152,000 genetic profiles — including convicted offenders, suspects, and crime scene samples. By 2027, this is expected to grow to 200,000 profiles.
Technological Foundation
In 2024–2025, CIFS has implemented:
- Automated DNA analysis system (Next-Generation Sequencing);
- Integrated software for real-time profile matching;
- Blockchain-secured data to prevent tampering and unauthorized access;
- AI algorithms to predict links between crimes.
International Cooperation
Thailand actively collaborates with global agencies:
- Interpol: data exchange via the secure I-24/7 network;
- FBI (USA): technical support, training, access to CODIS methodologies (but not the database itself);
- Europol: joint investigations on human trafficking and drug crimes;
- ASEANAPOL: regional DNA data-sharing network among ASEAN countries.
In 2024, a Memorandum of Understanding was signed between CIFS and the FBI on expert exchange and joint investigations of transnational crimes.
Legal Framework & Ethics
Since 2022, the Forensic DNA Identification Act regulates:
- Sample collection only from convicted persons and suspects in serious crimes;
- Data storage in secure centers for up to 10 years (immediate deletion if acquitted);
- Ban on using DNA for non-investigative purposes;
- Independent oversight by the National Human Rights Commission.
Real-World Impact
Since 2020, the DNA database has helped:
- Solve over 1,200 serious crimes, including 140 murders and 320 rapes;
- Identify 89 unidentified bodies;
- Exonerate 37 innocent individuals through DNA evidence;
- Identify 12 serial offenders through case matching.
Outlook 2025–2027
Expected:
- Establishment of an ASEAN DNA hub based at CIFS;
- Expansion to transnational criminals and cybercrime suspects;
- Integration with biometric systems of police and border control;
- Development of educational programs in forensic genetics at universities.
"DNA is not just evidence — it’s the victim’s voice," said CIFS Director Professor Somchai Thananakul. "Our goal is not only to catch criminals, but to restore justice."
