"Digital evidence - evidence that is stored on or transmitted by computers - can play a major role in a wide range of crimes, including homicide, rape, abduction, child abuse, solicitation of minors, child pornography, stalking, harassment, fraud, theft, drug trafficking, computer intrusions, espionage and terrorism." "This work explains how computers and networks function, how they can be involved in crimes and how they can be used as a source of evidence. As well as gaining a practical understating of how computers and networks function and how they can be used as evidence of crime, readers will learn about relevant legal issues and will be introduced to deductive criminal profiling, a systematic approach to focusing an investigation and understanding criminal motivations."--Jacket.
