Forensic Biology Time Line by Texasdude25 77

1248 - First Forensic science book

mhrueda2577 — 2024-09-03 21:00:37 UTC

The first known forensic science text, "Xi Yuan Lu" or "The Washing Away of Wrongs," was published in China by Song Ci. This book is the earliest recorded handbook for coroners, providing detailed instructions on how to distinguish between accidental and deliberate drownings and more.

1784 - First Recorded case of physical matching evidence

mhrueda2577 — 2024-09-03 21:02:52 UTC

In England, John Toms was convicted of murder based on the physical match of a torn piece of newspaper in his pocket to a piece found in a gunshot wound on the victim. This is one of the earliest known instances of forensic evidence used in a legal case.

1835 - First use of bullet comparison

mhrueda2577 — 2024-09-03 21:04:08 UTC

Henry Goddard, a member of Scotland Yard, used bullet comparison to solve a murder case. He noticed a distinctive mark on a bullet that matched the mold used by the suspect, leading to a conviction.

1880 - Fingerprint evidence introduced

mhrueda2577 — 2024-09-03 21:05:30 UTC

Dr. Henry Faulds and Sir William James Herschel independently published research on the uniqueness of fingerprints and their potential use for identification, laying the groundwork for forensic fingerprinting.

1892 - First fingerprint identification in a criminal case

mhrueda2577 — 2024-09-03 21:06:41 UTC

Juan Vucetich, an Argentine police official, used fingerprint evidence to identify a suspect in a double murder case, marking the first use of fingerprints to solve a crime.

1901 - Discovery of blood types

mhrueda2577 — 2024-09-03 21:08:32 UTC

Karl Landsteiner discovered the ABO blood group system, which later became crucial in forensic blood analysis for identifying individuals based on blood type.

1910 - First Forensic Laboratory

mhrueda2577 — 2024-09-03 21:09:32 UTC

Edmond Locard, known as the "Sherlock Holmes of Lyon," established the first forensic laboratory in Lyon, France. He formulated the Locard Exchange Principle, which states that "every contact leaves a trace," foundational to modern forensic science.

1923 - Establishment of the first crime laboratory in the U.S.

mhrueda2577 — 2024-09-03 21:10:51 UTC

August Vollmer, the Chief of Police in Los Angeles, established the first crime laboratory in the United States, which later became part of the Los Angeles Police Department.

1932 - FBI crime laboratory established

mhrueda2577 — 2024-09-03 21:12:00 UTC

The Federal Bureau of Investigation established its own forensic laboratory, which became one of the most advanced and comprehensive crime labs in the world.

1984 - Development of DNA Fingerprint

mhrueda2577 — 2024-09-03 21:12:48 UTC

Sir Alec Jeffreys developed DNA fingerprinting techniques, revolutionizing forensic science. DNA profiling became a powerful tool for solving crimes, identifying suspects, and exonerating the innocent.

1986 - First use of DNA evidence in criminal investigation

mhrueda2577 — 2024-09-03 21:13:52 UTC

DNA profiling was used for the first time in a criminal case in the UK to identify Colin Pitchfork as the perpetrator in the murder of two young girls, marking a milestone in forensic science.

1991 - Mitochondrial DNA Analysis

mhrueda2577 — 2024-09-03 21:14:41 UTC

The FBI began using mitochondrial DNA (mtDNA) analysis, which is useful in cases where the DNA is degraded or there is only a small amount, such as in old bones or hair.

1996 - National DNA Database

mhrueda2577 — 2024-09-03 21:15:34 UTC

The United Kingdom established the first national DNA database, which allows law enforcement agencies to store DNA profiles of individuals and use them in criminal investigations.

2002 - Introduction of Touch DNA

mhrueda2577 — 2024-09-03 21:17:01 UTC

The concept of "touch DNA" was introduced, referring to DNA that can be recovered from very small samples, such as skin cells left behind when a person touches an object. This expanded the scope of DNA analysis to more types of evidence

2007 - Development of Next-Generation sequencing (NGS)

mhrueda2577 — 2024-09-03 21:18:18 UTC

NGS technology allows for the sequencing of DNA at a much faster rate and lower cost than previous methods. It has enhanced the ability to analyze genetic material from crime scenes, even from mixed or degraded samples, significantly advancing forensic DNA analysis capabilities.
