Note: not ‘labelled after sealing to prevent contamination or several items together’
True
Scene: window frame with tool marks
Action:
- photograph
- take control samples
- remove area for examination
True
Digital imaging guidelines direct that any image to be produced as evidence must:
- be validated by the taker
- downloaded on a police/secure computer
- secured in a master copy format
True
Photos taken at the crime scene:
- must only be printed from police computer
- are subject to disclosure
- cropped or enlarged for booklet
True
Digital cameras should be assigned to named position or employee
True
Notes should be examined first, not fingerprinted at the scene
True
When uplifting a phone:
- Leave it switched on
- Uplift and contact ECL for advice (Electronic Crime Lab)
True
Collect wet blood by sterile and dry swabs
True
- Deleted images CAN be retrieved
- Deleting images in a digital camera WON’T OR SHOULDN’T remove the images from the camera
- Digital images at the scene SHOULD be taken on an approved camera
- Reformatting camera WON’T remove images
True
Any tool or sharp blade to be forwarded for DNA analysis should be packaged in a tube or cardboard box, taped, sealed and signed
True
Sequence for uplifting exhibit:
- record in situ
- notebook record of significance
- collect/uplift
- seal and secure
True
Latent Prints are:
- revealed by use of reagents
- sometimes obliterated in search
- not visible to eye
True
Fire debris to be sealed in clean airtight tins
True
Scene records including photos; sketches; drawings and notebook entries to be completed prior to search and uplift of exhibits
True
Safety Precautions:
- cover hands with double gloves
- package securely
- discard used gloves
- do. It package wet material
True
Exhibits collected should be uplifted; packaged and examined by people wearing gloves and protective clothing
True
Minimum standard for DNA items:
- handle one time at a time
- wear gloves and masks
True
Get SOCO to 1S scene as latent prints might be on the body
True
Basic Electronic Rule:
Off leave off
On leave on
True
Exhibit in a paper bag: must fold bag over 2-3 times and seal with tape
True
Adopting a search pattern assists to examine the scene in a thou rough and controlled Manner
True
Full protective clothing must be worn by anyone:
- entering hot zone
- transitioning too hot zone
- examining exhibit in hot zone
(Not when processing in warm zone)
True
Exhibit Schedule contains:
- photographs and video/DVD tapes
- ID no. of each exhibit
Note: NOT ‘all material gathered for analysis’ or ‘only those collected at the crime scene’
True
Reconstruction is t
A theory about what happened in the area over time
True
Examples of crime scenes subject to forensic scrutiny:
- Get away car
- Suspect located soon after
- Series of documents in Fraud
- Victim of an assault
NOT police interview
True
When managing Hot Zone, O/C has too:
- brief examiners on search
- establish transition area
- display instructions on clothing
NOT place guards at Hot Zone
True
Types of evidence at the scene that help with Modus Operandi:
- how offender entered scene
- what property damaged
- where and when crime occurred
True
O/C exhibits role:
- check LABEL on each exhibit
- prepare DOCUMENTS to accompany exhibits
- maintain LOG of exhibit movement
- check exhibit PACKAGE sealed and signed
- check COLLECTION is safely secured
True
Situation to most likely lead to cross contamination:
When scene equipment is reused without cleaning
True
O/C scene must ensure persons working in scene:
- package in clean and dry containers
- directly briefed about zonal requirements
- use gloves to remove and package exhibit
True
Common Approach Path (CAP) is used to control access to the scene to prevent contamination
True
It is not the job of the O/C to establish the relevance of exhibits to the enquiry
True
Zoning a Scene helps too:
- control ACCESS to the crime scene
- establish set rules for EVIDENCE collection
- provide a FRAMEWORK for managing the scene
- maintain APPROPRIATE standard for safety
- avoid CONTAMINATION of scene and exhibits
True
Scene examination strategy record provides an overview of management strategies and procedures etc
True
Decontamination Zone Model is used at major scene as the scene will contain both biological and physical evidence
True
Search descriptions:
Zone = separate areas
Spiral = concentric circles
Lane = even parallel lines
Grid = even squares
True
Stepping plates:
- used to direct pathway
- easily placed and moved
- easy to clean and reuse
True
Scene guard briefed too:
- prevent unauthorised access
- alert to circumstances of contamination
- keep notebook of all movement
True
When communicating scene examination strategy the O/C scene must instruct:
- where scene BRIEFINGS occur
- how FORENSICS conducted
- how scene SECURITY managed
- search PATTERN for scene
True
Log movements into zones:
Hot Zone - each examiner logs in and out (clip board hanging between warm and hot zone)
Cold Zone - scene guard logs movements in and out
True
COLD ZONE:
- log book records
- scene strategy communicated
NOT clothing or packaging exhibits
True
WARM ZONE:
Collecting; recording and securing the exhibit collection
True
Scene Reconnaissance:
- Reconnaissance is preliminary INSPECTION OR SURVEY OR RECONSTRUCTION of the scene
- Recon include and deliberate a purposeful SEARCH of the scene
- The outcome of recon by the O/C scene is a plan for ACTION
- Recon encompasses a 4 step APPRECIATION or pathway
True
Essential info at initial action for O/C scene handover is details of any post incident movement in the crime scene
True
DNA can be collected from samples of:
- hair
- cigarette butts
- liquid and dry blood
True
