Unit 3 CSI Discussion collection of evidence
Topic 1: What Evidence Should Be Documented?
Give a brief description of the order in which evidence should be documented, collected, and preserved. Your answer should include the role of potential contamination in your decision-making process.
Topic 2: Latent Prints
Discuss at least two of the chemical methods used to raise latent prints and advise your classmates on what piece of evidence you would process that way. Be sure to choose a different piece of evidence from your classmates
The evidence collection process is very extensive and must be accurately recorded and preserved. First there should be a plan of action. This includes making sure everyone at the scene knows how the evidence will be documented. If not all are on the same course of action important evidence could be damaged or removed. For example if an investigator walks on a footprint that was left by the suspect it probably won’t be able to get an accurate picture of the evidence and it is lost.
The next step is for the investigator to take notes of the crime scene. The process of note taking should be extensive, containing even notes they may seem insignificant but may become valuable evidence later (Fisher & Fisher, 2012). At this point evidence should not be moved or touched. Next pictures are taken at the crime just as it happened. The pictures should include scales to show accuracy in the evidence produced. Next is sketching the areas where the evidence was found is a way to support the picture evidence at court. The sketches should be accurate and contain measurements of the scene.
The last process is to collect and package the evidence in the proper containers. The evidence that is the most important is that evidence that is fragile and can be contaminated easily. This might include fingerprints and blood evidence that could break down quickly. All evidence should be put in separate containers so that the evidence does not get contaminated by another piece of evidence. Firearms should be

    Some kinds of evidence rely on honesty and trust. Direct evidence and testimonies both require help of people in the case you are in. Those people can twist the story, make the situation seem better for them, or sometimes they completely lie without a speck of truth. Forensic evidence doesn’t have to rely on truth. The evidence you gain from it has no argument. If you ask them if they committed the crime, they could lie and tell you no.…
