In this revised and expanded edition of his critically acclaimed Criminal Poisoning: Investigational Guide for Law Enforcement, Toxicologists, Forensic Scientists, and Attorneys, leading forensic scientist John Trestrail offers a pioneering survey of all that is known about the use of poison as a weapon in murder. Topics range from the use of poisons in history and literature to convicting the poisoner in court, and include a review of the different types of poisons, techniques for crime scene investigation, and the critical essentials of the forensic autopsy. The author updates what is currently known about poisoners in general (psychological profile, types, and statistical analyses) and their victims (who gets poisoned, investigative considerations, and classic symptoms of poisoning). The Appendix has been updated to include the more commonly used poisons, as well as the use of antifreeze as a poison, to reflect some cases that have recently come to light.
