Crime mysteries solved by DNA testing: Forensic Identification Research Institute will reveal the latest research results and ongoing next-generation DNA analysis technology
Experts who are active on the front lines of DNA analysis and are also active in court cases and other practical situations will present the latest DNA research results and near-future analysis methods. ……
Forensic Identification Research Institute (Headquarters: Koganei City, Tokyo) announced the latest research results and near-future DNA analysis technology for DNA testing in criminal investigations. Led by the DNA analysis staff at the institute, the results of research using cutting-edge technology are being shown to the public, how they have helped solve many cases, and future possibilities. This announcement is an important step in contributing to solving crime mysteries through the power of science.
-DNA analysis technology and genetic testing technology are not end-of-the-world technologies that have all been clarified.
DNA analysis technology and genetic testing technology are fields with untapped potential that continue to evolve every day. What we are uncovering is only a small part of the vast world of DNA. In this article, a DNA expert at the Forensic Science Identification Institute explains how the latest forensic technology and DNA analysis can unravel criminal mysteries, and the current state of affairs regarding the full picture of DNA and the functions of genes, which still remain many mysteries. We will thoroughly explain the future.
Crime mysteries solved by DNA testing: Forensic Identification Institute -1. Importance and evolution of DNA testing –
The role of DNA testing in criminal investigations is becoming more important year by year. It has become possible to identify criminals from minute samples of DNA with an accuracy that was impossible a few decades ago, and breakthroughs have also been made in the
re-investigation of unsolved cases. DNA testing identifies individuals using small amounts of evidence such as blood, hair, and skin pieces, and is widely recognized legally due to its accuracy and reliability. According to a person in charge of DNA analysis at the Forensic Science Identification Research Institute, conventional DNA
identification technology was mainly based on amplification using PCR (polymerase chain reaction), but in recent years, more sensitive technologies have appeared. For example, analysis technology using next-generation sequencers (NGS) is becoming more widespread, making it possible to obtain more precise DNA information from smaller samples than before.
-2. Progress in DNA analysis shown by the latest research-
At the Forensic Identification Institute, analysis methods based on the latest research are being introduced one after another. According to the person in charge, methylation analysis is one of the latest DNA analysis technologies that will attract attention in the future. Methylation is a chemical modification added to DNA that is influenced by environmental factors and lifestyle. By analyzing this methylation pattern, it is possible to determine whether a person has been in a particular environment and to estimate their health status.
For example, methylation patterns can be used to determine how old a DNA sample comes from tissue or body fluids, or whether a person is old or follows a particular diet, which cannot be obtained using traditional analysis. You can extract information that was not previously available. This can be used in criminal investigations as evidence that the perpetrator was in a specific location.
Furthermore, the Forensic Identification Research Institute has begun researching a cutting-edge DNA analysis technology called “long read sequencing.” Conventional technology analyzes DNA information in short fragments, but long-read sequencing allows long fragments to be analyzed at once, making it possible to create a more complete DNA profile. This makes it possible to obtain more information even if the DNA is degraded.
-3.The power of DNA testing seen in actual cases-
We will introduce specific examples of crimes that were actually solved by introducing the latest technology. The Forensic
Identification Laboratory has used DNA testing to help identify criminals in numerous cases.

For example, in an unsolved case, new DNA analysis was performed on evidence collected decades ago, and the culprit was identified. In this case, a minute amount of sample, which was difficult to analyze using the technology available at the time, was accurately analyzed using new technology, leading to the resolution of the case. Cases like this increase the chances of old unsolved cases being
re-investigated and demonstrate how important forensic laboratory technology will be to future criminal investigations.
-4. Possibilities of future DNA analysis technology-
Future DNA analysis technology is about to evolve even further. For example, automated DNA analysis using AI enables rapid response in the field. Currently, analyzing a DNA sample can take hours or days, but with the help of AI, this time could be reduced to just minutes. This will speed up the initial response at the scene of an investigation, and will play a major role in identifying criminals and preserving evidence.
Additionally, the Forensic Identification Laboratory is working on the development of a portable DNA analysis device. If this technology is put into practical use, DNA analysis can be performed directly at the crime scene, greatly reducing the risks associated with transporting and processing evidence. Immediate results at the scene increase the likelihood of preventing criminals from fleeing and leading to faster arrests.
-5. DNA testing and ethical issues-
On the other hand, with the evolution of DNA testing technology, ethical issues have also arisen. While DNA databases are increasingly being used in criminal investigations, issues of privacy and personal information protection are emerging. Forensic Identification Institute officials also emphasize that DNA data must be handled with care, and that guidelines are needed to utilize science and technology while protecting individual rights.
There is also the risk of false arrests and misinterpretation of results due to DNA testing. For this reason, a high level of expertise is required in the appraisal process and interpretation of results. At the Forensic Identification Institute, we are constantly introducing the latest technology while also seriously addressing these ethical issues.
-6. Conclusion: The future of criminal investigation opened up by science- DNA testing technology is a major key to opening up the future of criminal investigation. The latest technology introduced by the Forensic Identification Laboratory will completely change traditional investigation methods and enable more accurate evidence collection. As science evolves, unsolved cases will be solved one after another, and we look forward to seeing how future criminal investigations will change.
Advances in technology will make our society safer and fairer. The Forensic Identification Institute will play a part in this endeavor, and their DNA analysis technology will be the driving force that opens up that future.
