Establishing Standards and Upholding Fairness and Justice
Next-Generation Sequencing (NGS), a transformative technology in forensic science, is making significant strides in New York State, thanks to a new training initiative at Syracuse University.
The training, sponsored by the New York State Department of Criminal Justice Services Office of Forensic Services, aims to bring more consistency to the implementation and execution of NGS by crime labs throughout the state. The College of Arts and Sciences' Forensic and National Security Sciences Institute (Forensics Institute) is leading the effort to bring this advancement to New York State.
The first-ever NGS training was held recently at Syracuse University, offering students valuable opportunities to engage with and learn from leading professionals. Undergraduate and graduate students conducted practice runs with the technology under the supervision of project Principal Investigator Michael Marciano and Natalie Novotna before the session.
NGS is particularly beneficial for addressing the challenges posed by low-quantity, degraded, or mixed DNA samples. Traditional DNA analysis methods, which typically analyze around 20–24 genetic markers, often struggle with such complex evidence. In contrast, NGS enables the examination of a much larger number of genetic markers (for example, over 150 markers from a single sample), providing higher resolution and more detailed genetic profiles even when the DNA is limited or compromised.
This practical impact of NGS in forensic contexts was notably demonstrated in 2024 when Kern Regional Crime Lab in California used it for the first time in a criminal court case in the United States. This breakthrough highlighted NGS’s capability to clarify complex evidence and helped establish crucial investigative details, thus signaling a new era in forensic DNA analysis.
Moreover, NGS is crucial for discriminating between individuals in mixed DNA samples, which are common in crime scenes. By targeting the smallest DNA sequence differences, NGS offers forensic scientists improved accuracy and reliability in analyzing these challenging samples. This advancement has not only increased the forensic interpretative power but also expanded applications to non-criminal investigations such as missing persons cases.
Efforts to integrate NGS into forensic practice and legal systems are actively underway. The training at Syracuse University is part of New York State's initiative to train professionals in public crime labs on NGS technology, preparing these labs to leverage this powerful tool in court. This preparation aims to overcome traditional hurdles of technology acceptance in legal settings and to promote widespread implementation of NGS in forensic investigations.
By the end of the session and another planned for next May, representatives from crime labs in several counties and the New York State Police and the New York City Office of the Chief Medical Examiner will have received training at Syracuse. The weeklong training session featured experts from Qiagen, Opentrons, NicheVision, and Nimagen, as well as faculty from the Forensics Institute and instructors from the New York City Office of Chief Medical Examiner's Department of Forensic Biology and the New York State Police.
The Forensics Institute's mission is to foster collaboration among government agencies, private industry, and academia in advancing forensic science and national security. The training at Syracuse University highlights the University's commitment to preparing graduates with advanced, cutting-edge forensic research skills that translate directly to real-world applications.
In summary, the current state of NGS in forensic science is that of a rapidly advancing, increasingly adopted technology that significantly improves the analysis of challenging DNA evidence, supporting more accurate and comprehensive forensic interpretations and enhancing the judicial process’s reliance on genetic evidence. This training at Syracuse University marks a vital next step in the integration of NGS into forensic practice, offering solutions to previous limitations and broadening the scope and accuracy of forensic genetic evidence.
