1813 - Mathiew Orfila

  • Father of Toxicology

01

02

published the first scientific treatise on the detection of poisons and thei effects on animals

1880 - Alphonse Bertillion

01

01

started the systematic use of photography to document crime scenes and evidence

02

02

his method, photographing crime scenes with a camera mounted on a high tripod, to document and survey the scene before it was disturbed by investigators

1920 - Calvin Goddard

01

he brought professionalism

02

he uses of the scientific method, and reliability to Forensic Firearm Identification

1923 - Frye vs. United States

1923 - Frye vs. United States

01

this case had a crude precursor to what is now popularly known as a lie detector or polygraph test. The court also refused to let Frye introduce an expert witness to testify about the deception test.

02

In the court's opinion, the systolic blood pressure deception test had not gained enough "standing and scientific recognition among physiological and psychological authorities" to justify its admission as evidence in courts of law. The court approved of the exclusion of the deception test, and Frye's conviction was affirmed.

1932- Creation of the FBI Crime Lab

01

the lab was a key component in both the work and the image of the G-Men of the FBI and an important force for the professionalization of American law enforcement.

02

The Special Agent Appel solved many cases, he was the Bureau’s only scientist and its Technical Crime Laboratory had been in operation for little more than a year.

Locard's principle holds that the perpetrator of a crime will bring something into the crime scene and leave with something from it, and that both can be used as forensic evidence

The same holds true in digital forensics. Registry keys and log files can serve as the digital equivalent to hair and fiber

1975 - The Federal Rules of Evidence

1994 - NDIS

01

National DNA Index System (NDIS) is a system of DNA profile records input by criminal justice agencies

02

There are certain categories of information must be collected: 1) DNA identification records of persons convicted of crimes; 2) Analysis of DNA samples recovered from crime scenes; 3) Analysis of DNA samples recovered from unidentified human remains; 4) Analysis of DNA samples voluntarily contributed from relatives of missing persons; and 5) known reference sample from missing persons.
