The text covers the comprehensive realm of forensics and its role in criminal investigations. Physical evidence collection and preservation techniques are examined in detail including chapters on Computer Forensics and DNA.
In this new edition of Criminalistics, the noted forensic scientist Richard Saferstein brings the reader into the crime lab for a firsthand look at the role of science in the criminal justice system. Criminalistics focuses its attention on the up-to-date technologies police rely on to apprehend criminal perpetrators and to link them through trace evidence to crime scenes. This new edition emphasizes the latest DNA profiling technologies, which include STR and mitochondrial DNA. The book details how the creation of a new nationwide DNA data bank has been designed to apprehend the mobile criminal. Today, the ability to detect less than one-billionth of a gram of DNA means that forensic scientists can extract critical information at crime scenes from stamps and envelopes licked with saliva, a cup or can that has come in contact with a person's lips, chewing gum, the sweat band of a hat, or a bed sheet containing an individual's skin cells.
Forensic Science: From the Crime Scene to the Crime Lab, Second Edition, is designed to present forensic science in a straightforward and student-friendly format. Ideal for students with limited background in the sciences, topics are arranged to integrate scientific methodology with actual forensic applications. Discussions are focused on explaining state-of-the-art technology without delving into extraneous theories that may bore or overwhelm non-science students. Only the most relevant scientific and technological concepts are presented, keeping students focused on the practical knowledge they'll need in the field.
Richard Saferstein has carefully adapted his classic Criminalistics text to create a comprehensive program designed specifically for high school students and teachers.
