Define Appreciation
An appreciation is an ongoing process which involves continually thinking through each new piece of information as it is uncovered.
Benefit of applying the appreciation technique
‑ Manages risk
‑ Reduces uncertainty
‑ Eliminates duplication
‑ Ensures nothing is overlooked
‑ Effective use of resources.
Appreciation steps
- Aim
- Factors
- Courses open
- Plan
Questions to ask during “courses open” of the appreciation technique
- What are the possible results or consequences of each alternative?
- Which alternative is the most appropriate way to reach the objective?
- From these considerations, decide on the most appropriate course to achieve your aim.
Information to obtain from informants
- Identity and location of the suspect
- First hand account of what the complainant/informant knows
- Precise details of the location of the scene
- Circumstances leading to the discovery
- Identity of the victim
To reduce risk of loss or contamination, the complainant/informant may be asked -
- To return to the proximity of the scene, and guard it, if it is considered safe for them to do so
- Not to enter the obvious boundaries of the scene
- Not to touch or move anything
- To prevent others from entering or touching the scene
- To await Police arrival and identify themselves to the first Police at the scene
Three categories of victim’s medical status
- Alive and uninjured
- Alive but injured
- Shows no signs of life
When victim is alive but injured
If practicable, a detective should accompany the victim to hospital. Otherwise, a detective should attend hospital without delay.

A crime scene log records the details, time and purpose of all persons who enter, attempt to enter, or leave the crime scene, as well as any other activity around the crime scene which the scene guard perceives to be relevant to the case
Purpose of Crime scene log
A scene guard and the log maintained by that person, is employed in order to ensure
- There is no unauthorised entry into the scene
- Integrity of evidence or potential evidence is secured

Scene guard duties
