PURPOSE OF THE UNIT STANDARD 
This unit standard will enable learners to analyse and reconstruct an incident scene for forensic investigation purposes. The learner will use scientific methods, physical evidence, deductive and inductive reasoning and their interrelationships to gain explicit knowledge of the series of events that surround an incident scene. The learner will be able to use technology and scientific information to collect tangible physical evidence-gather and interpret clues- for possible use in the judicial process. Learners credited with this unit standard will possess detailed knowledge of international forensic standards applicable to incident scene reconstruction.

A learner acquiring this unit standard will be able to:
  • Analyse the incident scene for the purpose of reconstructing the scene.
  • Collate tangible physical evidence.
  • Review the quality of reconstruction scenes in a given situation. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    Communication at NQF Level 4.

    UNIT STANDARD NOTES 
    Definitions:

    Incident:
  • The overall crime or occurrence is the incident. The incident encompasses all actions related to the occurrence. Within this incident there are specific events.

    Event:
  • Each event is some part of the occurrence. Each event is defined by small, specific actions taken that are in turn supported by the presence of specific items of evidence.

    Event segments:
  • Each of the smaller actions ("snap shots") in the event is referred to as event segments.

    Event analysis:
  • This is the overall process in the reconstruction attempts to define the crime or incident by establishing the events in the occurrence.(crime or incident).

    Event flow charting:
  • This is the graphical ordering of the events into a logical and supportable sequence in a flow chart.
