Introduction
This training has been created to teach members of the Los Santos Police Service how to perform basic forensic activities.
By the end of this training an officer should be able to :
Explain the reason why officers should take an individuals fingerprints;
Explain when an officer can take an individuals fingerprints;
Have an understanding of how to take an individuals fingerprints;
How to use and what to do with filled in fingerprint cards;
Understand and be able to conduct Gunshot Residue (GSR) Tests
Introduction to Fingerprints
What are Fingerprints
Every individual has a unique set of fingerprints. These fingerprints are all assigned a unique identification code which can be searched for on the Police National Computer (PNC) and linked to an individuals citizen ID should the individual be identified.
Why should an officer take an individuals fingerprints
As an individuals fingerprints are unique they provide indisputable evidence of an individual whether that be that that individual was present at a crime scene because their fingerprints have been found there or the fact that they were the individual who was in custody.
Because of this every time a suspect is brought into custody they should have their fingerprints taken so that they cannot, at a later date deny it was them. This also allows incident reports to be recorded under the fingerprint ID instead of a persons PNC profile and this can be especially useful in cases where an individual is failing to identify themselves.
When can an officer take and record someone's fingerprints
An officer can take and record an individuals fingerprints in the following situations:
The individual is suspected of an offence and is in custody;
The individual has given their consent for fingerprints to be take and recorded.
Fingerprint Equipment
Once an officer has completed their fingerprint training then they will have access to fingerprint card from the police armoury. These cards are incredible useful items that allow an officer to record an individuals fingerprints so that they can be presented as evidence at a later date.
Taking Someone's Fingerprints
To take an individuals fingerprints an officer must take the person to a police station where there is a designated location for fingerprints to be taken
Mission Row
Vespucci Police Station
Sandy Shores Police Station
Palito Bay Police Station
Davies Police Station
2.. Once the individual is at the designated location the officer should put on Surgical Gloves and then either remove the gloves of the person who is to be fingerprinted or ask them to remove them.
3. The officer should then use Archies Eye on the individual and select the Check fingerprint details
4. After the electronic fingerprint device has scanned the individuals fingerprints it will give the officer 3 Options:
Update Linked Citizen ID
Print Fingerprints onto Card (if the officer has a blank card)
Copy Fingerprint ID
5. The officer should then select the "Print Fingerprints onto Card" option. This will take one blank fingerprint card and give the officer two filled in fingerprint cards
6. If the officer wants to search this ID in the PNC then they can open their inventory, right click on the fingerprint card and copy the fingerprint Identifier before pasting it in the person search
7. These cards contain sensitive information and as such should never be discarded onto the floor they should instead be placed into an evidence case file linked to the incident report or in the case of someone needing their fingerprints adding for a job then they should be given to the individual once their PNC profile has bene linked
Linking someone's fingerprints profile to PNC person Profile
Before linking a Fingerprint ID to a citizen ID the officer must be sure the person is who they say they are. When it comes to identifying someone please refer to the Identification Guide
Get the Citizen ID and Fingerprint ID for the individaul (Note: It may be useful to have the fingerprint ID on your clipboard and have the citezen ID Written Down)
2. Navigate to the Fingeprint ID on PNC
3. Press Edit Identity Button
4. Insert the Citizen ID into the Citizen ID box then press Save
5. Check the link on the fingerprint ID PNC pace to make sure it is linked to the correct person
Gunshot Residue (GSR) Tests
What is GSR
When a firearm is discharged the explosive charge releasing millions of particles into the air in all directions. Because of this the particles can be found on the firearm, the shooter, surrounding objects and if close enough the victim. This is called GSR and is easily identified by tests.
Why should an officer check for GSW?
Checking for GSW allows an officer to gather evidence as to weather an individual has recently fired a firearm or not and can be very useful if a suspect denies discharging a firearm.
Limitations of GSR Testing
while GSR testing is very good it does have some limitations and the biggest being that it is very easy for an individual to remove traves of GSR from them by changing their cloths. As such if an officer has proof an individual has discharged a firearm they should still proceed as the individual may have changed their cloths since.
Performing GSR Tests
GSR Tests are conducted in the same place that fingeprints are taken as can be seen in the fingerprints section above.
2. An officer should use Archies Eye on the individual, interact with them and then select GSR Test
3. The results of the test will appear saying if the suspect has GSR residue or not
