  25. Chapter 4: Fingerprints “Fingerprints can not lie, but liars can make fingerprints.” —Unknown

  26. Fingerprints Students will learn: • Why fingerprints are individual evidence. • Why there may be no fingerprint evidence at a crime scene. • How computers have made personal identification easier. Kendall/Hunt Publishing Company

  27. Students will be able to: Fingerprints • Define the three basic properties that allow individual identification by fingerprints. • Obtain an inked, readable fingerprint for each finger. • Recognize the general ridge patterns (loops, whorls, and arches) • Identify friction ridge characteristics and compare two fingerprints with at least ten points of identification. • Explain the differences among latent, plastic, and visible fingerprints. • Develop latent prints (make them visible) using physical and chemical methods. Kendall/Hunt Publishing Company

  28. The History of Fingerprinting

  29. The Chinese • In the eighth century during China’s T’ang dynasty, Chinese used thumbprints to seal important documents and on business contracts. • There is no record of whether they were actually used for identification, and there was no systematic classification. Kendall/Hunt Publishing Company

  30. Quntilian, the Roman Lawyer • Made use of a bloody handprintin a murder case in 1000 AD Kendall/Hunt Publishing Company

  31. A number of people throughout history noted fingerprints and even commented on the different ridge patterns. However, the science of dactyloscopy, the study of fingerprints,(comes from the Greek word daktulos, meaning finger) really started in the 19th century in India with William Herschel.

  32. William Herschel • Highly placed civil servant who decided to require Indians to add their fingerprint to contracts. • Later (1877) he introduced the use of fingerprints as a means of identifying prisoners. Kendall/Hunt Publishing Company

  33. HenryFaulds • In Japan, molded fingerprints in old pottery piqued the interest of Henry, a health missionary in Tokyo . • He published a scientific paper in 1880 about the possibility of using fingerprints to identify criminals. • Thought that fingerprints were unique. • Could be used for classification • Said fingerprints did not change over a lifetime. • First to use fingerprints to solve a crime. Kendall/Hunt Publishing Company

  34. Prisoners • Identification has always been a problem for the criminal justice system. • Prisoners were often branded or tattooed or even had hands or fingers chopped off so they would be recognized as criminals. • This practice was generally abolished in the Western world in the early 1800’s. Kendall/Hunt Publishing Company

  35. Photography • The advent of photography helped, but without a means of classification, the police records were soon overwhelmed with too many photographs to be useful. • They often employed men with “photographic” memories. Kendall/Hunt Publishing Company

  36. Alphonse Bertillon • 1881 • Employed as a ledger clerk at the police headquarters in Paris, suggested using 11 body measurements to identify habitual offenders. • Was accepted almost everywhere. • The science of human measurements was called anthropometry. • This was initially the system that most police departments used for personal identification. Kendall/Hunt Publishing Company

  37. *Alphonse Bertillon (1853-1914) • 1879 • First system of personal identification. Wrote his first book on anthropometry. • Known as the father of personal identification • Began the development of anthropometry – a systematic procedure of taking a series of body measurements as a means of distinguishing one individual from another. • Was eventually replaced by fingerprinting in the early 1900’s.

  38. Francis Galton • 1891 A British anthroplogist - Published two books in which he showed how to classify fingerprints using loops, whorls, and arches. • He showed that: • 1. a person’s fingerprints stay the same from birth until death. • 2. no two fingerprints are identical • 3. prints cannot be altered • And said it is possible to classify a very large number of prints. Kendall/Hunt Publishing Company

  39. Sir Edward Richard Henry • 1897 – Inspector general of police in Bengal, India. • Simplified Galton’s classification system in India • Established the Henry System of Classification which replaced Bertillon’s system. • England’s (FBI) Scotland Yard, adopted the Henry System • Henry System is used in most English speaking countries. Kendall/Hunt Publishing Company

  40. JuanVucetich • 1901 – Argentinean police official • Set up a workable fingerprint classification system based on Galton’s method • Used in most Spanish speaking countries. Kendall/Hunt Publishing Company

  41. Juan Vucetich • 1902 – a year later, Vucetich first officially identified a criminal using fingerprints. • In a small town in the province of Buenos Aires, Argentina, a woman named Francesca Rojas had murdered her two sons and blamed the attack on a neighbor. • Using Vucetich’s methods, police identified bloody fingerprints on a door post as Rojas’s, which led to her confession. Kendall/Hunt Publishing Company

  42. Civil Service Test • 1902 – The New York Civil Service began the practice of fingerprinting everyone who took a civil service exam. Kendall/Hunt Publishing Company

  43. Leavenworth Prison • 1903 - The death of Bertillon’s anthropomorphic classification. . . . Mainly because . . . • A man named Will West arrived there to serve time. • When convicted, he received an extra severe sentence because he was a repeat offender. • He protested the sentence, stating that he had never been convicted before. • As was done with all prisoners on admission, his Bertillon measurements were taken and compared to existing files. Kendall/Hunt Publishing Company

  44. Will and William West • Prison officials were astonished to find that another man who was serving a life term for murder had almost identical measurements, and even more amazing, his name was William West . . . And he looked almost the same as the new prisoner! • The two men’s fingerprints were taken and, of course, were quite different! Kendall/Hunt Publishing Company

  45. a. Will West b. William West Kendall/Hunt Publishing Company

  46. 1903 – The New York State prison system started fingerprinting all the inmates. • 1904 – because of the William West case, Leavenworth Penitentiary also switched to fingerprinting as its primary means of personal identification. • 1905 – the U.S. Army began using fingerprints , and the U.S. Department of Justice set up the Bureau of Criminal Identification in Washington D.C. to centralize and standardize the use of fingerprinting. Kendall/Hunt Publishing Company

  47. 1907 – The Navy began using fingerprints, and the Bureau of Criminal Identification was moved to Leavenworth Penitentiary. • 1918 Edmond Locard recommended that 12 points of comparison be required to prove the identity of an individual. • 1924 – the U.S. Congress established the FBI as the central repository for all fingerprint information. • By 1946 it held 100 million fingerprint cards. Kendall/Hunt Publishing Company

  48. IAFIS • 2004 – The FBI crime lab identification section began using the Integrated Automated Fingerprint Identification System (IAFIS). • It can search 47 million records in 5 minutes! • Assuming good quality, IAFIS requires only one print for a match! • The final identification however, is always done by hand by a forensic expert. • The more than 250 million fingerprint cards already collected are still kept on file. • If piled on top of each other, these records would make 133 stacks as high as the Empire State Building!
