Detective Bureau
Information Regarding Forensic Requests


1.1 Overview
This notice is going to be going over some guidelines relating to forensic requests. It'll highlight what you, as an investigator and a holder of a CSI qualification certificate, are capable of doing as a standalone qualified officer without the requirement of trained laboratory staff having to handle it.

First and foremost - The Technical Services team are still limited in numbers overall. We are made up of specialized forensic analysts who are trained in performing laboratory work following a crime scene, as the job entails. However, we are not always available to conduct every request that comes across us simply due to constraints in our team's size, and backlog. This is being addressed with a new batch of analysts coming in, but still will remain a small section. Please keep this in mind.

Qualified CSI certificate-holding officers, as per the current revision of the CSI Manual, still entitle you to utilize and conduct light laboratory work. The qualficiation awards you with the neccessary knowledge & training to do so. I ask of you to please remember that fact when it comes to forensic work requests.

Regarding request work itself - Please ensure the priority you assign is appropriate to the work required, as a high or urgent priority should only be utilized if it's appropriately needed, and sparingly due to staff size. Below will list what would be considered each level of priority. A house robbery is not as high priority as a double homicide. Fingerprint lifting are not as high a priority as a GFR swab analysis. Ensure you take this into consideration, and understand the cogs involved in making the Section turn.

Below is a list of different topics surrounding common requests. Below those, exists the TLDR version. But I urge you read the entire topic. Thank you.
2.1 Procedures

2.2 Fingerprints
  • Fingerprints are one of the most common forms of identification we all have our disposal. Most cases will involve fingerprints in some form.

    A qualified CSI-certified officer, may operate laboratory equipment regarding developed fingerprints following a crime scene. Most requests involving fingerprints have had the certified employee develop the fingerprints already, to be utilized in laboratory work. Seeing as it's already developed on your behalf for the purpose of a request - As you are certified, you have access to utilize the Integrated Automated Fingerprint Identification System for comparisons to existing samples. ((In our case, the MDC. If your suspect(s) or victims have existing MDC fingerprint entries, you have your match result there and then. If not, they simply don't and you cannot definitively state so.)) Please use this before sending already developed fingerprints over for analysis, it will only result in the same process.

    Non-Certified officers would not have the creditials to utilize this system. However the majority of Detective Bureau personnel are CSI-certified. In the event you are not certified, roleplay that fact accordingly and reach out to a certified officer, or Technical Services member to be able to utilize IAFIS. ((Again, in our case it would be just MDC automatic fingerprint matches. No sample, no match - unless suspect consents to their prints being matched on a database. Then you may use that information.))

    Should no sample exist for the person, then you must send in a request, e-mail or contact Technical Services in order to do a deeper analysis, or discuss the possibilty of such. I ask that you, prior to this, have neccessary OOC information (Confirmation from suspect, some enlightment details regarding the scene etc.) regarding who, where and how aspects of that crime tie to the suspect. Most of you do this already, but it helps speed up the process for all parties involved. Before you go forward with requests, ensure you have sufficient information to warrant the utilization of requesting work be done.

    TLDR; If below critera met - you may use relevant laboratory equipment (IAFIS/MDC) for automatic match.

    - Certified CSI Officer/Detective/Technican
    - Developed Fingerprints with an existing MDC record on suspect
    - Already have OOC Information regarding suspect/consent
    - OR Have OOC Consent from the suspect their fingerprints exist on a database already

2.3 Ballistics
  • Ballistics analysis are another common form of requests we recieve.

    A qualified CSI-certified officer may operate laboratory equipment regarding certain ballistics following a crime scene. Most requests involve asking us to check a firearm to be utilized in laboratory work. While this is fine, you can actually check some preliminary information yourself, providing the firearm contains a serial. As you are certified, you have access to utilize the National Integrated Ballistic Information Network/NIBIN for comparisons to existing samples. ((In our case, the MDC and the /casing command. Existing casings on our system are linked to the serial that ejected them. As these would have IC'ly been logged when you 'Turn in Casings', they are on the database. You can use /casing testserial X, IC'ly at the ballistics terminal in the lab. If it provides a match, then you can use that information without needing to send the gun to us to check.))

    Like above in 2.2, this system only allows the valid creditials of a certifed CSI officer/detective/technician to use. Reach out to one if you are not certifed and require the use of this system.

    In the event that the weapon does not contain a serial, then you must send in a request, e-mail or contact Technical Services for a deeper analysis or discuss the possibilty to do so. Once again, I ask you have some preliminary information at the ready before pursuing this, as it will help speed up the process. If it resulted in the death of a victim, please try your best to get the Coroner report with the information box visible that contains the fragment serials, so that we can pursue those serials for a weapon. This will help us get a match without needing to fire the weapon. If you cannot provide that, then we will run water-tank exemplar tests to get sufficient casings to see if other casings exist on the system. If no match, then the weapon has not been utilized in previous cases/or is unknown to law enforcement.

    ((If the suspect gives consent that their firearm, and/or casings found on scene match to a database, then you may use that information and factor it in for a automatic match status on the system. Their full consent supersedes what the script will spew out, as it can often lead to false no-matches scriptwise but the suspect is fine and content with their gun/casings matching.))

    TLDR; If below critera met - you may use relevant laboratory equipment (NIBIN IC'ly, /casing testserial OOC'ly) for automatic ballistic fragment matches.

    - Certified CSI Officer/Detective/Technican
    - Sufficent casings exist on the database for a match
    - Firearm of interest has a serial according to the script/inventory system
    - Have OOC Information regarding suspect/the firearm in question
    - OR Have OOC Consent from the suspect their firearm and/or casings exist on a database

2.4 DNA Analysis
  • DNA analysis is another form of common request we recieve here.

    A qualified CSI-certified officer may operate laboratory equipment regarding a threshold of a DNA sample has been met following a crime scene. Most requests involve asking us to check DNA samples that have been turned in. While this is fine, you can actually check some preliminary information yourself, providing the sample came from the suspect with prior arrests. As you are certified, you have access to utilize the State DNA Index Systems varient of the Combined DNA Index System/CODIS for comparisons to existing samples. ((In our case, the MDC again. Please ensure that when you roleplay utilizing this system, you are accessing the State of San Andreas index of this system. You, in your capacity at the department would not have access to the entire CODIS database, unlike the other systems I mentioned. This is by design as its a powerful database, with laws surrounding it and with access not usually obtained unless it falls under a federal investigation.))

    Like above in 2.2 and 2.3, this system only allows the valid creditials of a certifed CSI officer/detective/technician to use the state-level index. Reach out to one if you are not certifed and require the use of this system.

    The State-level CODIS index lists everyone who has ever been arrested and undergone a DNA sample check (As is standard when you arrest someone.) in the State of San Andreas. There is a forensic index along with this system, that keeps profiles collected from crime scenes, however that is not as prevailant as an arrestee's DNA sample. This means, you should realistically only ever get the DNA match of the suspect on the system, if they had prior arrests. Should a victim's (if involved) DNA be found - it should only provide a match if they too have a record with DNA on file. We most likely will never utilize the non-criminal portion of this database, such as the Missing Persons Index or the Unidentified Human Remains Index.

    ((If the suspect gives consent that their DNA, in any shape or form is found to match a database, then you may use that information and factor it in for a automatic match status on the system. Their information is required to conduct these investigations anyway, but in the event they are not on the MDC, but give consent, then the match could be IC'ly linked to the entire State-level CODIS index. If they want their DNA known, then so be it.))


    TLDR; If below critera met - you may use relevant laboratory equipment (State DNA Index System/SDIS) for automatic DNA sample matches.

    - Certified CSI Officer/Detective/Technican
    - Suspect has prior arrests or a MDC record with a DNA sample on file
    - Sufficent enough of a DNA sample that could provide a realistic match
    - Have OOC Information regarding suspect(s) in question
    - OR Have OOC Consent from the suspect their DNA exist on a database already

2.5 Gunfire Residue Analysis
  • GFR analysis is another form of common request we recieve here.

    A qualified CSI-certified officer must perserve the GFR sample, and request, e-mail or speak with a Technical Services member in order to perform a laboratory analysis on GFR samples. A qualified CSI-certified officer may utilize a field-test kit on a swab containing GFR, with the use of the provided investigation kit in their patrol vehicle's trunk. This test, however, will only provide a preliminary result as it will test positive for the presense of said residue, but will not provide accurate lasting results, and not hold up in court. This is why ideally you should request a follow up confirmation on the GFR to cover yourself, after you made the arrest and whatnot following the positive test result.

    ((You must ensure you ask follow up OOC questions in regards to GFR. As you will be doing that anyway at any rate, ensure the information is saved and when you request or speak via email to TSS, you can provide the consent the suspect gives that they had GFR present on their clothing/hands/whereever.))

    TLDR; If below critera met - you may use a field test kit (Found inside your standard CSI kit) for a GFR positive, followed by requesting the laboratory to follow up.

    - Certified CSI Officer/Detective/Technican
    - Sample has not surpassed 6 hours and been preserved
    - Will ensure to send the sample to the laboratory and make neccessary follow-up request
    - Have OOC Information regarding suspect(s) in question

This guideline will be focused on the proper handling, and collection of; Firearms & Ballistics.
Synopsis
A Predominant scenario in which the use of a firearm is utilized is all-too common in the city of Los Santos and it's surrounding environs. More than likely, members of the Detective Bureau and ultimately the Police Department as a whole have investigated some aspect of gun-related crime in their duties, and even more likely have had to collect and dispose of these weapons following their investigation. Be it a victim of gunshot wounds, or a weapon used in a robbery-homicide, the collection of this evidence is extremely important to the investigation in which they were utilized.

Evidence Collection Guidelines for Firearms & Ballistics
Firearms
  • First and foremost, when you arrive to process a scene of any form - make sure you equip yourself with the necessary protection gear before performing your duties. There are two primary reasons for this. One, is to protect you from the evidence. The other is to protect the evidence from you. Most common-practice item to wear is a set of Nitrile gloves, powder & latex free for ease when processing a scene.
  • When you wish to handle the firearm, never pick up the weapon by placing an object such as a pencil or similar in the end of the barrel. Document the item as found, photograph it, and then visually examine to see if it would be safe to handle. If determined safe, pick it up in a manner which would not disrupt any latent prints, or trace evidence that might be found on common-grip areas of the weapon. Preferably handle it from the back-strap and have a evidence securing bag nearby to minimize exposed handling. Make sure it is unloaded in a manner that would not disrupt evidence of the given firearm.
  • Never clean the bore, chamber or cylinder before submitting the firearm. Do not attempt to fire it either. Refrain from utilizing any levers or locks due to possibly hampering trace or latent print evidence. Only do so in the event to render the weapon accurately safe if you are unsure.
  • Never submit a loaded weapon for evidence, unless it is delivered in person to the Laboratory. Unfired cartridges maybe be left in the magazine of the firearm, provided the magazine itself is removed from the weapon and separated in another evidence collection bag. A firearm with a cartridge/projectile in the chamber should never be submitted for evidence by any method, even if the weapon has it's safety mechanism triggered, or the weapon is not cocked.
  • Record the serial number, make, model and caliber of the firearm, if possible. A neat trick to learn with firearm processing, is marking it in some inconspicuous manner that will not disrupt evidence. This is a easy identification tool to learn in the event duplicate serial numbers are found with different weapons and causes confusion. Learn the weapon, try and not confuse model numbers with serial numbers.
  • Rifles or shotguns should not be disassembled outside the controlled environment of the Laboratory.
  • If available with larger-sized weapons, place them in strong, secure containment boxes. This prevents shifting of the weapons during transit which could possibly disrupt trace evidence.
Ballistics

Bullets
  • Recovered bullets must be sealed in separate labelled pill-boxes, if available. If not, wrap in strong-paper provided for Tool Marks which is standard in any CSI kit, and secure in a evidence bag.
  • Submit all evidence bullets that are recovered to the Laboratory. A conclusive identification of the projectile may only be possible on one of the several bullets recovered. It is a good measure to submit all, not just ones deemed visually decent for analysis.
  • Never mark bullets with an identification marker.
  • Do not attempt to clean the recovered bullets before sending them to the Laboratory. The bullets that are recovered from a body for instance, should only be air-dried and secured. Washing them may destroy the trace evidence present.
Cartridge Cases
  • Any recovered cartridge case should ideally be wrapped with a outer-layer of paper and then be sealed and secured in labelled a evidence bag or envelope.
  • In a case relating to a fired shotgun shell, these may be marked on the outside of the plastic-portion of the shell for identification later on. Refrain from marking the inside portion.
  • Submit all obtainable cartridge cases or shotgun shells for evidence. Some of these cartridge cases contain more identification details than others, making Laboratory analysis work quicker in determining an outcome.
Ammunition
  • When coming across unused ammunition, make it a habit to try recover all the available unused ammunition you come across for comparison purposes. When a firearm is obtained as evidence, it'll make the comparison easier. If the unused ammunition is not with the firearm itself, subjects of interest often have additional ammunition in their vehicles, clothing, or houses. Always try and retrieve these, as they may be important for exemplar purposes to duplicate exactly what make type and age the ammunition was in conjunction with the crime.
  • Unfired ammunition must never be marked. The box containing the ammunition, providing it does not disrupt trace evidence, may be marked for identification purposes before submitting it for analysis. Each round contained inside the box should not be marked, nor needs to be.
  • Do not attempted to extract the unfired ammunition contained in a box. Cleaning, or moving the unfired rounds may disrupt or damage trace evidence contained inside. If any form of visual evidence is seen on or inside the box, document it and refraim from inspecting it deeper and have it submitted for evidence as it may contain usable evidence such as blood or other fluids.
Gunshot Residue
  • Gunshot residue is an extremely fragile form of evidence, and should be extracted and collected as soon as possible. The accepted time frame in which usable GFR can be obtained is within three hours of the firearm being discharged.
  • In the case of a live subject, if more than six hours have passed since the discharge of the firearm, or the subject has washed their hands, clothing or surrounding area in which it was discharged, it is unlikely that usable results will be obtained.
  • In the case of a deceased body, gunshot residue collection should be performed prior to moving the body. A sample is to be extracted before doing so, however in the event the body needs to be moved due to external forces, such as exposure to the weather, protect the hands and wrist of the the deceased with issued paper-bags. This is not a sure-sign to preserve GFR, but it can help.
  • Every standard CSI kit contains gunfire residue sampling tools. Police Department-registered vehicles all contain a form of this kit, so if possible, the handling detective or CSI-qualified officer should take a gunfire residue sample the moment they are available to do so. Waiting on an external source to collect it for you, could be damning to the overall case.
