In Preparing these slides

In Preparing these slidesI made a few assumptions:

• You have an interest in forensic science• You are a fan of forensic shows on TV• You follow criminal cases on TV, newspaper, or radio• You are considering a career in the legal, judicial, or

forensics field• You love reading mystery stories• You are simply curious by nature• And finally…you chose this class because you

thought it was cool…

The Evolution of Criminal Investigation

Understanding the history of forensics

Forensic Science• The word itself stems from the Latin

word forum, which simply means “law”• Forensic Science is simply the

application of scientific principles to law• However, forensics has not been accepted for

very long

1750• Henry Fielding – established the “Bow

Street Runners”• Fielding’s runners literally ran to a crime

scene to informally investigate the scene• The gathered information (much of it useless)

and reported it to anyone who cared• The gained the reputation and

acknowledgement as the first modern detective force

1829• British Parliament passed the Metropolitan Police

Act and created one of the first legally organized police forces

• This force was stationed at the world renowned Scotland Yard (the location of the modern London Police Department)

• The Scotland Yard was established and the force was selected by Sir Robert Peel• This accomplishment has earned Sir Peel as the

father of modern policing.

Scotland Yard• The department was headed by Sir

Peel, but two commissioners were chosen: Sir Charles Rowan and Sir Richard Mayne

• The department made up of several officers, office staff, and the administration occupied 4 Whitehall Place which opened up to the famous Scotland Yard

1857• The New York Police Department

organized a picture gallery of known criminals – Rogues Gallery

• Photos lined the walls like an art gallery so the public would know criminals identities

• Pictures were arranged first by height, and then by criminal specialty

1883• Alphonse Bertillon – established a

method of identifying criminals• Taking various body measurements to

establish a profile of a criminal• This system was very inaccurate and was

abandoned at the advent of dactylography (the study of fingerprints)

1900• Francis Galton – wrote the book

Fingerprints after extensive research finding solitary identity in a fingerprint

• In 1900, the Henry System was accepted and used as a system of criminal investigation

Homework Assignment• Do some research and write a ½ page

summary of the Henry System used in fingerprinting• Be sure to explain why the system is no

longer used

1908• The United States Congress passed a

bill enacting an investigative entity • The Federal Bureau of Investigation was

established under its original name of Bureau of Investigation (name changed in 1924)

1987• The discovery and mapping of DNA

was a huge milestone for Forensics• You all know the individuality and

importance of DNA• DNA profiling was first used in a case

in 1988, but was still considered new and controversial
