evidence, criminal

Presents a look at the people and policies behind the government agency known as the FBI, from its founding in 1908 to the controversies and challenges it faces today.

Examines the history and opinions surrounding the issue of DNA evidence from the early use of fingerprinting to identify civil servants, to the latest advances in DNA typing in criminal investigations.

What is forensic science and how is it used to solve a crime? How do you know if a red stain is blood or ketchup, or whose blood it is? Can computers really recognize your face in a crowd? How do scientists decide how old bones are, and trace who they once belonged to? Explore the fascinating, and sometimes gory, world of forensics, where science helps crack the case. Learn why it is important to secure a crime scene, why fingerprints are critical clues, and how DNA sampling works. Find out how maggots can reveal how long someone has been dead, or how a single fabric fibre can lead to the murderer. From the scene of the crime to testing in the laboratory, you will get to know how all the clues are put together to tell a story and reveal the guilty person. Discover how methods have changed since the days of Sherlock Holmes, the latest technology in use today, and techniques of the future.

"An eleven-year-old boy's violated corpse is found in a town park. Eyewitnesses and fingerprints point unmistakably to one of Flint City's most popular citizens. He is Terry Maitland, Little League coach, English teacher, husband, and father of two girls. Detective Ralph Anderson, whose son Maitland once coached, orders a quick and very public arrest. Maitland has an alibi, but Anderson and the district attorney soon add DNA evidence to go with the fingerprints and witnesses. Their case seems ironclad" -- Provided by publisher.

The dead talk. To the right listener, they tell us all about themselves: where they came from, how they lived, how they died - and who killed them. Forensic scientists can use a corpse, the scene of a crime or a single hair to unlock the secrets of the past and allow justice to be done. Bestselling crime author Val McDermid will draw on interviews with top-level professionals to delve, in her own inimitable style, into the questions and mysteries that surround this fascinating science. How is evidence collected from a brutal crime scene? What happens at an autopsy? What techniques, from blood spatter and DNA analysis to entomology, do such experts use? How far can we trust forensic evidence? Looking at famous murder cases, as well as investigations into the living - sexual assaults, missing persons, mistaken identity - she will lay bare the secrets of forensics from the courts of seventeenth-century Europe through Jack the Ripper to the cutting-edge science of the modern day.
