Determining Status of Suspect
Responsibility for determining the status of a person within the investigation whether as a suspect, person of interest, witness or victim rests with the OC Investigation. It would be incorrect for the OC Suspects to make a unilateral decision to attribute an individual with the status of a ‘suspect’ where time was available for the OC Investigation to make that determination, albeit in consultation with the OC Suspects.
Suspect
A person of interest who has gained added status because of a direct or indirect connection to the circumstances of the crime. Such a connection might relate to motive, opportunity or means.
Briefing Suspects Team
The first duty of the OC Suspects is to brief their suspects team members. To enable them to do this, the OC Suspects should analyse the information available such as witness statements, police reports and information from the scene. Their initial briefing should encompass:
- Circumstances of the offence including an analysis of the scene and witness evidence
- Full details of all persons of interest and any suspect
- Details of any descriptions of suspects by witnesses
- Whether any particular modus operandi/crime signatures have been identified
Briefings / Debriefs
The OC Suspects phase must regularly debrief their team members on the enquiries they have conducted and the results of these enquiries so that they can maintain a constant flow of information at conferences, between the members of the suspects team and other investigation staff. Priority information must be brought to the attention of the OC Investigation as necessary.
Identifying Suspects
- Area canvass
- Intelligence analysis
- Police nothings linking suspect to area/vehicle
- Fingerprints
- DNA
- Witness evidence
- CHIS
- Enquiries with external government agencies
FACES
Consideration for witnesses who saw a suspect to complete a FACES sketch. This is a computerised facial identification system used to compile likeness of an offender from the description supplied by the witness and it should be completed early, while details are fresh.
Using photographs of clothing or duplicates of property used by suspect may be utilised in a combination of ways:
- For release to the media
- To be used by investigators during an area canvass
- In the conduct of suspect enquiries
Photograph Board
Should be set up displaying photographs and details of suspects whom you have interviewed and who you wish to interview
Suspects Residence
- NIA enquiries
- Enquiries with local council to identify owner
- Conducting a reconnaissance of the area
- Surveillance monitoring the address
- Monitoring phones through production orders or surveillance device warrant
Trace, Interview, Eliminate (TIE) Enquiries
A TIE category is created by selecting a common characteristic shared by a group of people, which may include the offender. These group characteristics will depend of the circumstances of the crime but examples might include persons related to or associated with the victim, persons in the vicinity of the scene at the time for the offence or with access to the scene at the time of the offence.
Suspect Team must conduct elimination enquiries by tracing and interviewing persons who populate these TIE categories and where possible, eliminating them against a set of elimination criteria determined by the OC Investigation.
Arrest/Termination
Before arrest/termination, the OC Suspects must consult the OC Investigation regarding an arrest strategy to ensure:
- An investigator is appointed to be responsible for each suspect
- Decision to prosecute, choice of charges and prosecution
- Clarity on Police position of bail
- Family of deceased are updated through FLO
- Prompt preparation of prosecution file
Cross Contamination
Where more than one suspect is involved, an appreciation must be made regarding which staff are assigned to seize clothing from suspects. It is vitally important officers involved are fully aware of cross contamination issues where possible, seperate officers should be assigned to each suspect. Suspects must be kept apart including during travel in vehicles and when in cells. All clothing should be packaged, labelled and sealed in accordance with standard procedures before transfer to OC Exhibits.
