1 History of Forensic Science Research based on Miami-Dade County Website

2 What is forensic science? Previously “______ medicine” was the term used for the application of medical knowledge to the investigation of a crime. Now we call it “forensic science” – Forensic refers to the use of material in a ____ of law

3 Where did forensic science start? The Chinese book Hsi Duan Yu (The Washing Away of ____), which appeared in 1248, provided the first association of medicine and law. – The book offered useful ____, such as distinguishing drowning (water in the lungs) and strangulation (pressure marks on the throat and damaged cartilage in the neck) from _____ by natural causes.

4 Where did forensic science start? The first appearance of ___ in the courtroom was documented around the end of the 18th century. The emergence of modern ______ around that period led to discoveries which were applicable to crime _______ and _______.

5 Important Cases in History: One of the ____ celebrated cases in forensic science involved the 'father of _______', Mathieu Orfila (1787-1853), who worked in Paris and testified in an _______ poisoning criminal trial in _____. Orfila and others had developed a chemical ____ to detect arsenic, the _____ of choice for the period because the symptoms, violent stomach pains and vomiting, were similar to _______ (a common disease of the times) and often went undetected.

6 Important Cases in History: Alphonse Bertillon's (1853-1914) personal ___________ system using a series of body and facial _____________ for individualization, developed in 1882. Dr. Francis Galton's (1822-1911) Fingerprints, published in 1892, was another pioneering contribution to the emerging field of ________ science.

7 Founder of Forensic Science! Alexandre Lacassagne (1844- 1921) has been called the _____ of modern forensic science. Lacassagne made many contributions including the first to recognize the significance of the ______ etched on a bullet extracted from a_____ victim and their link to the gun from which it was fired, thus beginning the science of _______.

8 Forensic Facts! Illinois suspended its death penalty after discovering that police ________ Pamela Fish had manufactured forensic evidence in dozens of cases!Pamela Fish If only they had caught her sooner!

9 Founder of Forensic Science! He also was the first to study the relationship between an attack on a victim and the shape and ________ of _________, and was first to recognize the need for adequate means of identifying ________ through a police ______ system.
