In 2022, one laboratory’s journey from traditional forensic DNA testing methods to next generation sequencing (NGS) was explored. In 2023, that journey concluded with the first successful admissibility hearing of NGS data in the United States. Identity SNP, aSTR and Y-STR DNA profiles obtained from the evidence collected from the crime scene samples of the double homicide were presented at the hearing and expert testimony was heard exploring the evolution of DNA testing, laying the scientific foundation for NGS technology, and addressing the applications of sequencing data for identification.
Laboratories considering implementing new technology, whether it be NGS or another advanced technology, are faced with a multitude of decisions, often making the task seem overwhelming. This presentation aims to address key components of the transition strategy including implementation considerations, case and sample selection for testing, expert witness selection criteria, and comprehensive trial preparation encompassing discovery materials and evidentiary presentation. A detailed case review will look further into how NGS was utilized in trial for the conviction of subject Adrian Chavez.
