DNA Forensic and Forensic Investigative Leads

Abstract

JH Smith1* and M. Singh

The chapter explores the fundamental principles of Deoxyribonucleic acid (DNA) in the context of forensic DNA profiling. Moreover, it explores the use of forensic DNA databases and the comparative searches carried out within them. The outcomes of these comparative searches produce Forensic Investigative Leads (FILs), which require communication with detectives for more investigation and follow-up. To successfully investigate these FILs, it is crucial to have efficient communication and engage in multidisciplinary detective work. This entails examining further corroborating evidence that could either absolve an innocent person from blame or contribute to the apprehension and compelling conviction of the perpetrator.
