Investigator

The Investigator's job is to investigate the remains of any crime, use evidence to identify the perpetrator, and then ask Security to arrest them for you. They have limited brig access because they are supposed to be an Investigator, not a Security Officer or Warden. They are expected to work in tandem with security - they handle physical evidence, while the officers can take general statements, your task may involve interrogation of witnesses and suspects.

General Guidelines
Step one. ALWAYS WEAR YOUR GLOVES. Acquire waistcoat and sunglasses. You are not an officer, so you do not need to adhere to their uniform expectations. You are expected to wear a business casual style of closing while doing your work. Find a lighter and a pack of smokes and have them at the ready, to add extra cool during panic situations. Outclass everyone on the station that isn't equipped with a top hat and cane.

Now that you look like the distinguished nerd you are, get acquainted with your lab. You will spend half your time here, when you aren't running from break in to murder to poisoning to autopsy. This is where the magic happens. See all the things on the tables around you? Grab all the things. Put them into your free CSI kit. It's the gray box on the rack. It has two layers of storage and can fit everything you need to fulfill your investigations. Do NOT lose it. If anyone steals it, you can order rather expensive replacements from the cargo department. If you arrive and your lab is already empty, find the other Investigator or Head of Security and find out where your stuff is.

Now that you have all the things, your CSI Kit should look like this. Note that you can put boxes inside it, so you can carry around boxes of evidence bags and swab kits with you. You could also take the microscope slides out of the box and repurpose the box for storing field evidence for whatever active case you're running. Makes it easier to keep track of what evidence is relevant to which investigation. You also have body bags in your autopsy lab, which you may end up needing.

Detainment And Use Of Force
You can't arrest crew members because you don't have access to the processing room or brig timers. You are allowed to detain a suspect if you directly witness an infraction and/or encounter a suspect with a pending warrant or arrest order. In any situation you need to call security officers to assist. This doesn't mean you should be joining manhunts to find a suspect - you don't have the tools to safely detain someone on the run and resisting. Basically, if you can't detain the suspect using only your flash and/or charming personality, just stay back and try to get officers on scene. Additionally only characters with a completed cadetship on their record are allowed to legally detain someone on station. Make sure to add this if your Investigator is more of an "in the field" person or be prepared to get poked about it by staff.

Your gun is only meant to be used in self-defense. When dealing with armed suspects stay on the periphery and let officers take the heat (and bullets).

Tools of the Trade

 * [[file:Suitcase_forensics.png]] Crime Scene Kit - Your trusty suitcase, which you can use to haul around all of your forensics junk.


 * [[file:Dustkit.png]][[file:Fingerprint.png]] Fingerprint Powder & Fingerprint Card - One of your primary tools. Use the powder on doors, weapons, clothes, or generally anything you suspect that has been touched by a criminal. If anyone has touched what you powder, you'll get a fingerprint card.


 * [[file:m_glass.png]] Fiber Collection Kit - One of your primary tools, but secondary to finding prints due to the interchangeability of clothing. Mostly used as supporting evidence in the case of partial prints that incriminate multiple people. Use it on doors, weapons, clothes, anything you suspect that has been touched by a criminal. If anyone has touched what you use it on, you'll get a bag of fibers.


 * [[file:uvgoggles.png]][[file:luminol.png]] UV Goggles & Luminol - The goggles currently do nothing, though they probably should/will do one day. The Luminol spray will reveal any blood that may have been sprayed away. You only get a limited amount of it per shift, though.


 * [[file:MS.png]][[file:Syringes.png]] Reagent Scanner & Syringe - Use the reagent scanner on any food or drink that's offered to you, before consuming it. Scan EVERYTHING that comes out of Chemistry, the Kitchen and the Bar. You'll analyze the chemical components of whatever applicable item you scan and each present chemical will be listed. Science can make Advanced Reagent Scanners that will show you the exact concentrations of each chemical in the mix, but the standard version does not provide this information. You can use the Syringe to take a blood sample from someone you suspect to have consumed either drugs or poison, and then analyze it for confirmation.


 * [[file:Tape_sec.png]] Police Tape - When you arrive at a crime scene you should use this to tape off every possible entryway and prevent contamination of potential evidence. Throw out anyone who cuts the tape. Try not to completely block off a main hallway, unless it's absolutely necessary, and even then try to do your investigation and call in a janitor quickly.


 * [[file:Camera.png]] Camera - Useful to carry around with you. Considering you are not equipped with the offensive and defensive tools that an Officer has, you take an incriminating picture if the opportunity presents itself and then swiftly run the hell away.


 * [[file:Tape_Recorder.png]] Recorder - Useful in case you need to perform an interview, or turn it on in secret and try to goad someone into incriminating themself with their own words.


 * [[file:DNA_kit.png]][[file:Swab.png]] Box of Swab Kits - When there's a blood trail on the floor, and no body in sight, whap the blood with one of these to take a DNA sample. You can also swab bloody weapons, bloody clothes, or people mouths.


 * [[file:Box.png]][[file:Evidence_Bag.png]] Box of Evidence Bags - Anything with blood on, or that looks out of place at a crime scene, needs to be bagged before anyone else can touch it.


 * [[file:Labler.png]] Labeler - Slap labels on those nameless evidence bags unless you want to forget which bloody weapon was from what crime scene in relevance to what investigation. You can harass cargo for some empty boxes, label them accordingly and stash anything relevant in there.

Building a Case
The most important tenets in investigating crimes - sometimes called the legal burden of proof, or going beyond reasonable doubt - is to ascertain the following:


 * Motive - This is often the most difficult thing to determine, as it usually cannot be proven by material evidence, and is crucial to proper sentencing. Motive is the difference between an assault charge and attempted murder - vandalism to sabotage - and sedition to mutiny. In order to properly charge someone with capital crimes such as murder or terrorist acts, you must be able to prove intent. Often, the only way to ascertain motive is to convince them to tell you, however, use your better judgement. A suspect that fires on someone with a .357 revolver has pretty clear intentions, despite what they might suggest.


 * Means - Typically, forensics can uncover this. The means to which the crime was carried out is the bare-bones facts; the details. Usually, this is in the form of a narrative, explaining, in active practice, exactly how the crime was carried out. How someone broke into an area, through what means someone was assaulted. It is here that you must prove what it is exactly that they did.


 * Presence/Confirmed Involvement - Again, typically forensics can typically uncover this, although witnesses may also be able to provide supporting statements. Confirming presence or involvement simply means to be able to place a suspect at the area when the crime happened. Finding a suspect's fingerprints all over a murder scene, the AI reporting someone breaking into an area, or an officer or other witness providing testimony are all indicators that your suspect was present at the crime. This usually lays the foundation of your investigation and will give you your preliminary list of suspects - additionally, it is the easiest to prove, especially with forensics or photographic evidence.

Sometimes, however, there's going to be a witness but no evidence. You can interview witnesses in your office, and use their statements (which you can record with your trusty tape recorder) to obtain a warrant to have officers search or detain suspicious individuals.

Proper Proceedings
Have your printed dossiers with you or on file at all times - these dossiers act as the evidence against the criminal. Typically, a dossier - or case files, as they are sometimes called - consists of the following:


 * Fingerprint and fiber analysis reports, printed from the high powered-electron microscope
 * DNA analysis reports, printed from the DNA analyzer
 * Copies of the medical/security records of any suspects with matching fingerprints/DNA pertaining to your case
 * Photos of the crime scene, or of any incriminating action
 * Interrogation recording transcripts, of either witnesses or suspects
 * Signed confessions from suspects
 * Any forensics-related paperwork, such as autopsy reports, body-scan print outs, bloodwork forms, etc. (Most of these can be found from the paperwork database at any request console, under the security archives.)
 * A thorough case report summarizing your findings and evidence is an invaluable centerpiece to any case dossier.

After producing your dossier you will want to hand it to the head of security or equivalent, and then after properly labeling it, archiving it in the evidence locker filing cabinet.

You've found a Crime Scene/Body, Now What?
First, cordon off the area with the supplied police tape to ensure the crime scene isn't further contaminated by passerby's. Rest assured that many of the crew will try to involve themselves if the crime scene is in a public area. Some may even disregard the presence of your tape and walk right through a crime-scene, so if it's in a populated area try calling for an Officer to assist you in keeping the crime-scene from interference. Remember to wear your gloves so you don't contaminate evidence yourself.

Once the crime scene is properly taped off and free of loitering assistants, you can begin getting to work. Start by getting pictures of the location of the body, and any other suspicious items. Then, use your swab kit to sample blood if any is present at the scene. Then, begin collecting evidence and putting it in bags with your gloves on. Use your judgement as to what constitutes evidence or not. Bloodied knife? Evidence. Bag of chips? Probably not evidence if it was discarded in a main hallway, definitely evidence if found in a place it has no regular business being.

Make sure to lift the crime scene as soon as possible, so that crew can once again use the part of the station.

Take the blood samples to the DNA Analyzer to get them checked for DNA. Remember to close the lid after a sample is loaded, and open it again after ejecting it so you can get your next sample in. The analyzer can process one sample at a time, and will take a minute or so to produce its analysis. Once you have your results, you can compare your DNA strings to those stored in the medical records (which you can access in your office). If your victim has been disfigured or is otherwise impossible to identify, this is also your chance to put a proper ID on them.

Next, it's time to search for fibers and prints. You lift both of these from evidence using the Fiber Collection Kit and Fingerprint Powder respectively, and analyze them by putting them in your Electron Microscope. If you're lucky, the culprit might've handled valuable evidence (such as the murder weapon) without gloves, but if not you might always have a few fibers to go off on. Remember that for fibers, you need to transfer them to a microscope slide before before you can put them under your microscope (thankfully, each slide is reusable).

At this point, you more often than not have enough evidence to get security to bring it at least one major suspect, if not arrest them outright. Make sure to communicate your findings over the security radio, so sec can be on the lookout for suspects and send them to you for interrogation.

Performing Autopsies
If the body isn't in your custody, fear not! Medical may have mistakenly taken the corpse. Ensure to politely ask them for the whereabouts of the victim and ensure you remind them that you have first priority for the processing of victims of crimes or workplace accidents.

To perform an autopsy, you're going to need a scalpel,  autopsy scanner,  a mask, and a  pair of gloves. Make sure to put on the mask and gloves before you begin, to avoid contaminating the body or catching any viral pathogens it might still be carrying.

Then, use a health analyser to find out damage areas on the victim, and use the scalpel on every affected zone once (two cuts for the chest might be necessary). Make sure to scan every zone with the autopsy scanner, and get a printout when you're done. Voila, you have a list of every injury on the body, complete with precise time and responsible weapon. Make sure to communicate your findings with security over the security radio.

Lastly, one additional thing you can do if you can't find any evidence pointing to a cause of death on the body is to perform a reagents test. To do this, grab a syringe, get a blood sample from the body, and put it through the mass-spectrometer found in the morgue. The mass-spectrometer should give you an accurate reading of any chemicals that were present in the victim's body at the time of death. (Note: this can also be used on living victims if you believe they've been drugged.)

Sidetasks
Technically, the above represents the entirety of your job. Despite this, you will rarely be called upon to investigate a crime, since the victim is usually able to cry out for help and the perpetrator is quickly identified. Luckily, there are some other things that you can do instead:


 * Be a general assistant to Security - the warden may occasionally need prisoners escorted to medbay, or for spare jumpsuits to be retrieved for demoted personnel.
 * Use the camera terminal in your office or the lobby to scan the station. Look around for any crimes, then report it over the Security channel or head over there yourself. It's probably not a good idea to announce it over the general radio, or the criminal in question will usually realize that you're onto them and get away.
 * Update the security records. This is meant to be the Warden's job, but you'll be hard pressed to see him actually doing that.

Traitoring
You are capable of fabricating and falsifying evidence. Furthermore, you have prime access to the station's morgue, which can be very useful for disposing of, or obtaining corpses, and generally people will be less suspicious of you if you carry around weapons or dangerous chemicals. As a whole, be creative! Frame others for your own crimes! Induce the station in utter confusion!
