Forensic science is described as the application of the broad spectrum of sciences to reply queries of desire for the lawful technique, which includes both of those criminal and civil actions (Houck and Siegel 2006).

Several scientific studies have demonstrated which the depth of calcination reliably indicates intensity and length of warmth exposure. A standardized depth Device really should be implemented to reduce error, just like the a person created by Barnott et al.
Investigators use the varying heights and route of the traces of demarcation as indicative of directional flow.
