GENETICS
LABORATORY

DRAWING A GENETIC PROFILE

Each of our cells contains DNA, but that DNA is never identical from one individual to another. By comparing the DNA in two samples, experts can prove beyond a doubt whether they are from the same person.

BALLISTICS
LABORATORY

IDENTIFYING THE WEAPON USED TO COMMIT THE CRIME

Ballistics experts endeavour to identify the weapon used in committing the crime. They can do this because the gun leaves characteristic marks on the bullet, as it passes through the barrel, and on the cartridge case. These marks are unique and can be matched up with an individual weapon.

CHEMISTRY
LABORATORY

SEPARATING AND IDENTIFYING

Identifying chemicals is often a crucial step in solving a crime. Alcohol, drugs, poison, dyes, explosives and other substances all have distinctive chemical properties. Chromatography is widely used in forensic chemistry to seperate a sample into its different components, so that experts can identify and measure them.

FINGERPRINTS
LABORATORY

TOUCH AND GO

There are tiny ridges and furrows on everyone's fingertips that make a unique pattern, called a fingerprint. Whenever someone touches an object, he or she leaves a deposit of grease and sweat on the surface, even though the mark can't usually be seen with the naked eye. These fingerprints, once they have been located and lifted, can identify a suspect with almost complete certainty.
