EVIDENCE

Once a crime has been committed, police search for evidence to identify, catch, and convict the perpetrators.

This new title examines different types of evidence, how police identify and use them, and how that evidence is then applied in court.

Evidence also looks at how key types of evidence have affected real-life criminal cases, the increasing role of technology in processing and substantiating evidence, and the chain of custody and issues of evidence tampering.

The book also focuses on DNA evidence, which has become more prevalent in cases, and exonerated convicts as well as expert and eyewitness testimony.
