Lawyer wh used fingerprints t prve his clients were inncent. Pudd nhead Wilsn states that a suspect s fingerprints are: his signature, his physilgical autgraph, s t speak, and this autgraph cannt be cunterfeited, nr can he disguise it r hide it away, nr can it becme illegible by the wear and mutatins f time. Frensic Science: Fundamentals & Investigatins, e Cengage/NGL/Suth-Western 06 Histry 6 Ancient cultures used fingerprints as persnal markings BCE Fingerprints were pressed int clay tablet cntracts in Babyln and China. 64 Dr. Nehemiah Grew described the patterns he saw n human hands under a micrscpe. 7 Jhann Christph Andreas Mayer described that fingerprints are unique t each individual. Prbably first t recgnize this. 3 Jan Evangelist Purkyn described nine distinct fingerprint patterns. Frensic Science: Fundamentals & Investigatins, e Cengage/NGL/Suth-Western 06

Sir Francis Galtn verified that fingerprints d nt change with age. 96 Sir Edmund Richard Henry (and clleagues) created a system that divided fingerprint recrds int grups. Their wrk was the basis f the ten card. Frensic Science: Fundamentals & Investigatins, e Cengage/NGL/Suth-Western 06 9 Frensic Science: Fundamentals & Investigatins, e Cengage/NGL/Suth-Western 06 3
4 Histry (cntinued) 0 The FBI-maintained IAFIS had mre than 76 millin cmputerized fingerprints, mugshts, scars, tatt phts, and ther identificatin recrds. The system will sn be enhanced by Advanced Fingerprint Identificatin Technlgy (AFIT). 03 The FBI was integrating the ability t cmpare crime-scene palm prints with prints cllected at the time f arrest. Abut 0-30% f latent prints at a crime scene cme frm the palm r side f the hand frm the little finger t the wrist. 0 Frensic Science: Fundamentals & Investigatins, e Cengage/NGL/Suth-Western 06 Frensic Science: Fundamentals & Investigatins, e Cengage/NGL/Suth-Western 06 What Are Fingerprints? Fingerprints arise frm dermal papillae, the layer f cells between uter skin (epidermis) and inner skin (dermis) Frictin ridges start t at -0 weeks f gestatin and becme fully develped by seventeenth week Pattern cannt be altered easily prtected by epidermis Frictin ridges are series f hills (ridges) and valleys (furrws) n the skin f the hands and feet Frensic Science: Fundamentals & Investigatins, e Cengage/NGL/Suth-Western 06 4
5 Develpment f Fingerprints As frictin ridges develp, perspiratin glands are frmed and cnnect t pres in the epidermis Pres release waste materials such as sweat, ils, prteins, fats and ther materials When finger tuches surface, these wastes are depsited, frming a fingerprint pattern that matches the frictin ridge pattern f the individual frictin ridges shwing pres emitting sweat Frensic Science: Fundamentals & Investigatins, e 3 Cengage/NGL/Suth-Western 06 Characteristics f Fingerprints 4 Frensic Science: Fundamentals & Investigatins, e Cengage/NGL/Suth-Western 06 Arches, Lps, Whrls Categrized by the presence r absence f a delta (triangular intersectin f ridges) An Arch has NO deltas A Lp has ONE delta A Whrl has TWO deltas Frensic Science: Fundamentals & Investigatins, e Arch Lp 5 Cengage/NGL/Suth-Western 06 Whrl 5

14 Can yu alter yur fingerprints? In mst cases, the act f alteratin will make the fingerprints easier t ID by adding cuts/scars t the ridge structure Example: Jhn Dillinger (930 s) put acid n his fingers, but did nt destry his ridges cmpletely Recently Mythbusters did a segment n making casts f fingerprints and verlaying them Frensic Science: Fundamentals & Investigatins, e 40 Cengage/NGL/Suth-Western 06 The Future f Fingerprinting Fingerprints can be scanned at a reslutin f 500 t 000 dts per inch. Nanparticles have been added t fingerprint pwders making pr patterns appear even sharper. The materials that we tuch leaves trace evidence n ur fingers and hands, which is in turn is left behind n the bjects we tuch. 4 Frensic Science: Fundamentals & Investigatins, e Cengage/NGL/Suth-Western 06 4 Frensic Science: Fundamentals & Investigatins, e Cengage/NGL/Suth-Western 06 4
15 Summary Humans have nticed the patterns n their hands fr thusands f years, but it was nt until 64 that these patterns were described in detail. In the mid-00s, the idea f a fingerprint s uniqueness was studied, and the applicatin f fingerprints t an identificatin system began. By the late 00s, tw effective systems were being used t identify criminals, and fingerprints were being cllected as evidence in crimes. The elevated regins in a fingerprint are called frictin ridges. Fingerprints cnsist f several main ridge patterns, including whrls, lps, and arches. They have a cre, which is an area where ridges separate r unite after running in a parallel directin. The triangular regin lcated near a lp pattern, r whrl, is called a delta. Fingerprints are frmed in the wmb at abut week 0 f gestatin. They are frmed between tw layers f skin, and their shape des nt change during a persn s lifetime. They are unique t an individual. Nt even identical twins have identical fingerprints. 43 Frensic Science: Fundamentals & Investigatins, e Cengage/NGL/Suth-Western 06 Summary (cntinued) Fingerprints left n an bject are created by the naturally ccurring ridges in the skin f fingertips and secretins frm sweat glands that leave small amunts f ils and salts when the ridges are pressed against an bject. The residues leave an impressin f the ridges fund n the finger f the dnr. The basic types f fingerprints are patent (visible) fingerprints, plastic (indentatin) fingerprints, and latent (nt visible t the unaided eye) fingerprints. They are characterized as lps, whrls, r arches, and are cmpared n the basis f their minutiae. Criminals have sught t alter their fingerprints with chemicals, surgery, and superficial destructin. Sme fingerprints can temprarily be altered by lng-term cntact with rugh surfaces. Attempts at permanent fingerprint alteratin have nt been successful. 44 Frensic Science: Fundamentals & Investigatins, e Cengage/NGL/Suth-Western 06 Summary (cntinued) 45 Mistakes in fingerprint analysis have led t wrngful cnvictins, mstly because f human errr. New frensic standards are being develped thrugh the Scientific Wrking Grups and the Organizatin f Scientific Area Cmmittees. The Integrated Autmated Fingerprint Identificatin System (IAFIS) is a natinal database that hlds mre than 76 millin fingerprint, identifying mark, and criminal histry recrds. Fingerprints can be cllected frm surfaces by dusting them with certain pwders and impressing them n tape, r putting them int cntact with certain chemicals that help reveal the fingerprints.
