Trace evidence is evidence that occurs when different objects contact one another. Such materials are often transferred by heat induced by contact friction.
The importance of trace evidence in criminal investigations was shown by Dr. Edmond Locard in the early 20th Century. Throughout the past century, forensic scientists have used trace evidence to reconstruct crimes, as well as to describe the people, places and things involved in them. Case studies of real life homicides have been published in the forensic science literature showing how trace evidence has been used to solve these crimes, free the innocent, and bring the guilty to justice. Trace evidence is also important in accident investigation, where movement of one part against another will often leave a tell-tale mark. Such analysis is of great use in forensic engineering.

Famous quotes containing the words evidence and/or trace:
“Nor is any evidence to be found, either in History or Human Nature, that nations are to be bribed out of a spirit of encroachment and aggression, by humiliations which nourish their pride, or by concessions that extend their resources and power.”
—James Madison (17511836)
“Tis chastity, my brother, chastity.
She that has that is clad in complete steel,
And like a quivered nymph with arrows keen
May trace huge forests and unharbored heaths,
Infamous hills and sandy perilous wilds,
Where, through the sacred rays of chastity,
No savage fierce, bandit, or mountaineer
Will dare to soil her virgin purity.”
—John Milton (16081674)
