The Devil's Dozen: How Cutting-Edge Forensics Took Down 12 Notorious Serial Killers
A forensics expert follows the historic evolution of CSI through a century of serial killers.
"Katherine Ramsland has brilliantly captured the insights and drama of some fascinating cases" (Dr. Henry Lee) in her previous bestselling books. Now she examines the case histories of twelve of the most notorious serial killers of the last one hundred years, and answers the questions: What clues did they leave behind? How were they eventually caught? How was each twist and turn of their crimes matched by the equally compelling weapons of science and logic?
From exploring the nineteenth century's earliest investigative tools to remarkable twenty-first century CSI advances, The Devil's Dozen provides a fascinating window into the world of those who kill-and those who dedicate their lives to bringing them to justice.

It seemed astounding that a man would do this, but Fish had many different religious delusions that involved being a martyr. He claimed he had performed a similar act on some of his victims.

However, his attorney, James Dempsey, insisted that Fish was a psychiatric phenomenon, stating that “no single case history report, either in legal or medical annals, contains a record of one individual who possessed all of these sexual abnormalities.” After deliberations, the jury agreed with the prosecution, convicting Fish of murder. (Some later said they agreed that he was insane but thought he should be executed nonetheless.) As Fish awaited his sentencing, he

At the culmination of the analysis, the genetic proﬁle of Lynda Mann’s rapist was revealed, but when it was compared to R.B.’s sample there was no match. However, the work continued for the next “nail-biting” week on the semen removed from Dawn Ashworth, which was then compared to that from Lynda Mann. This time there was a match, but not the one expected. The samples matched each other, so while the same person had

The agents could hardly believe that this short, scrawny guy was responsible for a dozen murders, but it wasn’t their job to make that
