Area Canvass Flashcards
What is the purpose of an area canvass?
A methodically conducted area canvass presents a high likelihood of identifying or contacting the offender, an associate of the offender, significant witnesses, identifying evidence or exhibits and establishing significant facts.
What are the responsibilities of the OC Area Canvass?
They report to the OC Investigation and together must ensure the canvass is conducted thoroughly and recorded accurately. The OC Area Canvass must ensure the area canvass team remains focused and that the canvass results in efficient use of resources and the return of relevant and manageable information and material.
What are some of the main objectives of an area canvass?
- identifying the offender
- identifying and locating evidence
- identifying witnesses
- gathering information
What are some of the other benefits of conducting an area canvass?
- sightings of the victim or offender before or after the event
- sightings of relevant property or vehicles
- sightings of potential witnesses
- creating the opportunity for an early arrest through early identification of the offender
- obtaining key information to drive the investigation or develop lines of enquiry
- promoting awareness of significant occurrences
- eliminating unidentified vehicles or persons reported by other witnesses
- obtaining an accurate record of the local community
Why must an area canvass be reviewed regularly?
As new evidence is gathered the facts and circumstances change and so the same or different areas may need to be covered.
What should occur before an area canvass commences?
An initial appreciation should be conducted to determine whether a full area canvass phase is required and the method and timing of enquiries to be made.
What are the timings of the initial area canvass phase?
An initial area canvass will normally be conducted when Police first attend the incident. A formal area canvass will normally follow and re-visits are generally required.
A good time to conduct the canvass is the time at which the offence occurred.
What is the key to effective management of resources in an area canvass?
Planning and foresight.
What are some relevant sites to conduct an area canvass?
- scenes
- premises within the line of sight of scenes
- access and egress routes to and from scenes
- areas where an offender may have lain in wait
- location where the victim was last seen alive
- locations or premises frequented by the victim
- locations of similar or previous incidents identified by intelligence as having occurred in the same locality as the offence under investigation.
Who can be used when setting parameters for an area canvass?
Specialist Police units such as the Behavioural Science Unit or criminal or geographic profilers
Once the location parameters are set, intelligence systems should be analysed to establish whether there are any people or events in the area which those carrying out the enquiries should be aware of. This may include
- violent offenders
- persons wanted by police for other crimes or wanted on warrant
- groups with particular linguistic or cultural needs
- local incidents or issues which residents may raise with Police
In relation to an area canvass, what time parameters shout be set?
Times for:
- the offence
- the scene
- sightings
- previous residents and visitors at the scene
- consideration of people’s varying work times.
People residing or working in the area of the offence may have relevant information. These witnesses may be peripheral or significant to the investigation and may include people who have witnessed:
- events connected to an incident under investigation
- sightings of the victim or offender before or after the event
- sightings of other potential witnesses
- sightings of relevant property or vehicles.
What resources should the OC Area canvass try to obtain?

2 - Emphasise the need for thoroughness and that every person in every household and visitors must be seen personally.
3 - Stress that the questionnaire is only a guide and should be regarded as flexible in that information supplied could lead to other questions.
4 - Advise that evidence of possible probative value must be obtained in a formal written statement rather than notebook form.
5 - Consider visiting the canvass area to record every address including flats and vacant sections and then reconcile these premises with the map.
6 - Ensure all forms are completed, and actioned as outlined.
