Genetic fingerprinting, blood splatter analysis, laser ablation, toxicology, ballistics analysis - the whole range of forensic techniques is featured. The investigators trust only the evidence to speak for those who cannot speak for themselves: the victims.
The cases featured include:
- Tommie Lee Andrews, the first person to be convicted as a result of DNA evidence, for raping a woman during a burglary;
- Jeffrey Gafoor, convicted of murder in 2003 when crime scene evidence collected twelve years previously resulted in a match with his nephew;
- Richard W. Rogers, convicted of the murder of two of his numerous gay male victims, through vacuum metal deposition, technology which saves fingerprints from plastic bags;
- Dr. Sam Sheppard, the murder trial based on blood evidence that inspired the TV series The Fugitive;
- Edwin Bush, the first murderer in Britain to be brought to book thanks to an identikit picture;
- Derrick Todd Lee, the Baton Rouge Serial Killer, only nailed by DNA evidence after a flawed FBI profile led big-shot investigators astray.
These cases - usually successful, but also sometimes dangerously flawed - offer a remarkable insight into real-life scene-of-crime investigation.
