==Getting Started ==
===Overview===
 
Because a lot of people want to know how to play with the fancy tools and Sue doesn't want to explain it.

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. 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. BONUS TIP: Grab one of the Heavy Duty Flashlights before the Red Tide does. You can put it on your belt slot.
 
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 become useless and should space yourself in shame. If you arrive and your lab is already empty, find the Detective or Head of Security and find out where your stuff is.[br]

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. I tend to 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 Morgue access, so feel free to run on down and grab a body bag. You'll probably need it.

Let's break down that menagerie of equipment and explain what each piece does and why it's important. Some of it we will need to return to later.
 
 
[[File:fprint.jpg]] [[File:fingerprintcard.jpg]]- 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:fcollect.jpg]] - 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:Uvglasses.jpg]] [[File:luminol.jpg]] - UV Goggles & Luminol
 
The goggles currently do nothing, but I suspect they should/will do one day. The Luminol spray will reveal any blood that may have been sprayed away. You only get so much of it though, and I'm not currently sure if there's a Chemistry recipe to make any more.
 
[[File:reagentscan.jpg]] [[File:syringe.jpg]] - 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:policetape.jpg]] - 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.jpg]] - 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:recorder.jpg]] - 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:Swabkit.jpg]] [[File:swab.jpg]]- 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:Evbags.jpg]] [[File:evbagempty.jpg]]- 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:labeler.jpg]] - 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. I usually harass cargo for some empty boxes, label them accordingly and stash anything relevant in there.
 
 
===Crime Scene===
For the purpose of this document, a protohuman was requisitioned. Most criminals are not stupid enough to discard the incriminating weapon at the scene of a crime, but it will do to show the tools and processes available to you.
 
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.
Image
 
As you can see here, we have a corpse, a bloody weapon, and a bloodstain. We should be able to identify a culprit from this. Take a swab kit and sample the blood on the weapon, and the blood on the floor. You can load one sample into the DNA analyzer at a time, and it will take a minute to perform its analysis. Remember to close the lid after a sample is loaded, and open it again after ejecting it so you can load your next sample.
 
Image
 
With the lid closed, begin your scan!
Image
 
Once it is complete, the analyzer will print a report for you. Remove the sample, set it aside, and load the next sample. When that's done you will have two reports.
 
ImageImage
 
As you can see, the blood on the weapon matches the one on the floor. Make a note of the DNA string. Go over to the medical records terminal in your office, log in and go through 'Search Records'. Here you can input a DNA string and return a list of any matching crewmembers.
 
Image
 
In this case, the protohuman is not listed on the crew manifest and thus the console will return no results. But if it were, then the console would instantly show you the medical record of the crewmember with that DNA string on their file. We have successfully identified the victim and the murder weapon! Now to begin narrowing down the suspects to determine the culprit. Return to the weapon and search it for fibers and fingerprints. If you're lucky enough to find anything the corresponding fingerprint card and fiber bag will come pre-labeled.
 
First, insert the fingerprint card into the electron microscope at the rear of the office and begin your analysis. You'll have a couple settings to choose from to help refine your analysis, and all three will not be applicable to the same item. In this case, we want to identify the fingerprint string found on the crowbar. Select that option and wait for the machine to finish its' work and print you a report.
 
Image
 
As you can see, we have determined a unique string. However it is very incomplete. The culprit must have been cunning enough to wear gloves.
 
Image
 
Unfortunately, it's not much to go on this time. The completeness of a fingerprint string depends on whether or not the culprit was wearing gloves, and how frequently the weapon was handled. Had the culprit handled the weapon without gloves, you would be lucky enough to return a complete string such as this.
 
Image
 
Depending on your findings the next part might be quick and easy as it locates a precise match.
 
Image
 
Image
 
However, if you only have a partial string to go on you will likely return multiple results. In which case you will at least have narrowed your suspects to a more manageable list. In the case of the most incomplete of strings, you will have to manually look for any possible matches and apply a little investigative intuition. Fortunately we have other evidence to analyze now!
 
Return to your microscope with the fiber bag you collected earlier. Unlike fingerprint cards, you need to first carefully transfer fibers from the collection bag to a microscope slide before you can insert it. You are provided several of these each shift, and each one is reusable. With the sample loaded, this time you analyze the fibers. Read the report it prints for you to taker a look at the findings.
 
Image
 
In this case, the only fibers found were those that match black gloves. You will more often find the fibers from a particular jumpsuit that is unique to a job, or department, or from a piece of clothing that you have seen a member of the crew wearing. Be sure to inform the rest of the Security team of your findings, or your absence of findings. Just letting them know that the criminal wears black gloves can sometimes help guide officers to watch over certain crew members under suspicion and alert them that they are cunning enough to purposely foil investigative attempts.
 
BUT WAIT, THERE'S MORE! In part three we will address the final responsibility that falls to the Crime Scene Investigator; performing autopsies. Most Medical Doctors have the access and medical training to perform these themselves in the medical Morgue, however it may be required to perform them yourself in case the medical team themselves are under suspicion.
 
===Cadavers===
I hope you brought your body bag, because this where it gets messy!
 
Pull the open bodybag under the victim and close it up, then relocate the victim to the operating table provided in your office. Before touching the corpse directly, ensure you have your sterile mask and latex gloves on, otherwise you may find yourself catching an infectious disease from the body, if it is still hosting a viral pathogen. When removing the victim grab the body and place it on the surface. Remember, even when a victim has died, pulling them directly instead of grabbing them will result in a bloody mess all over your lab. And you don't want that. Place them on the table, like so.
 
Image
 
Aside from your viral protection gear, the tools you will need for this task are as follows, and are provided in the autopsy area of every CSIs office.
 
Image - The Scalpel and the Autopsy Scanner
To use these, first ensure that the victim is laid out on the operating table. Carefully perform a single incision on every bodily area, then analyze each area in turn with the Autopsy Scanner
 
Image
 
Print the results after you have scanned every possible area.
 
Image
 
Tada. You can tell exactly where, and how many times a victim was assaulted, and the precise time of death. As always, be sure to communicate your findings and be ready to assemble all relevent evidence and information into a report. You never know when your your superiors may request it. And a criminal that's returned to CentCom without any accompanying evidence is far more likely to not recieve the full punishment for their alleged offenses.
 
But now you have a body in your lab, and probably other work to do. Your last task is to see the body to its next destination. For most this will be to the medical Morgue. You inform the geneticist, or Chief Medical Officer, of the corpse and it becomes their responsibility to see the person cloned. Remember, do your best not to reveal the death to the crew member if they are cloned. Others may be in posession of the appropriate paperwork for them to be rendered into indentured servitude after their death, in which case you take the body to the Roboticist, where they will perform the operation to transfer the brain into an unstoppable Durand a helpful cyborg. In the worst case scenario, the body will neither accept cloning nor are they eligible for cyborgisation. In this case the cadaver goes to the Chaplain, whose duty it is to perform last rites, perhaps hold a ceremony, and then grant the body a dignified Space Funeral.
