The murder of Inge Lotz is one of the most controversial homicide investigations in South Africa's history. A lone fingerprint police claim to have lifted from a DVD case led to the acquittal of the alleged murderer, and resulted in accusations of fabricated evidence.

Dr Scott Chadwick is a fingermark detection expert. His research focuses on optimising existing fingermark detection techniques and developing new reagents for revealing fingermarks on the most challenging of surfaces.  

In this episode, join host Kathryn Fox, and hear about the science behind the acquittal of Inge Lotz's accused killer, and the importance of transparent and accurate crime scene investigation.

Crime Insiders executive producer Dan Mullins presents a look back at one of our earlier episodes.
