Legal

The killing of one human being by another; classified as murder, manslaughter, or justifiable.

I

Impression Evidence

Criminalistics

Evidence produced when one object is pressed against another, leaving a mark, such as tyre tracks or tool marks.

L

Luminol

Chemistry

A chemical that produces a blue bioluminescent glow when it contacts blood, used to detect blood traces at crime scenes.

M

Mass Spectrometry

(MS)Chemistry

An analytical technique that measures the mass-to-charge ratio of ions to identify compounds.

N

Narcotics Analysis

Chemistry

Laboratory procedures used to identify and quantify controlled substances.

O

Odontology

Pathology

Forensic dentistry; the application of dental science to legal matters, including victim identification.

P

Post-mortem Interval

(PMI)Pathology

The time elapsed between death and discovery of a body, estimated through various biological indicators.

Q

Questioned Document Examination

(QDE)Document Examination

The examination of documents to detect alterations, forgeries, or to establish authorship.

R

Rigor Mortis

Pathology

The stiffening of muscles after death, used as an early indicator of post-mortem interval.

S

Serology

Biology

The study of blood and body fluids; in forensics, used to identify and characterise blood stains.

T

Toxicology

Chemistry

The study of poisons, their effects, and detection; forensic toxicology analyses biological specimens for drugs and poisons.

U

Ultraviolet Examination

(UV)Criminalistics

The use of UV light to visualise trace evidence, forgeries, and biological fluids invisible to the naked eye.

V

Voir Dire

Legal

A preliminary hearing to determine the admissibility of expert witness testimony or evidence.
