In the last decade, the scientific foundations of a number of traditional forensic methods have come under increasing criticism by the scientific community, leading to their discontinuation or reduced effectiveness in criminal prosecutions. These challenges raise questions about the admissibility of certain type of evidence in current cases and the validity of previous convictions. We will discuss the basis of these issues and describe some of the work ongoing at LLNL to try and address some of them. In particular we will describe an entirely new science-based approach to human identification. Series: "Field Trip at the Lab: Science on Saturday" [Science] [Show ID: 32071]
