Week 5this Weeks Module Had You Work As A Csi Investigator To Solve

Week 5: This week’s Module had you work as a CSI Investigator to solve a number of cases. Let’s take some time as a group to evaluate that experience. Fingerprints and DNA are both types of individual evidence. That is, they are specific to only one person, except DNA, which is the same in identical twins. Eye-Witness accounts are not able to be “proven” reliable in the same way as physical evidence but is used in over 20% of cases and oftentimes, is quite convincing in a courtroom.

For your initial response, please answer the following question: If you were an investigator working a homicide scene, which of the following would you choose to utilize in your investigation and in what order? Please order them as 1st, 2nd, 3rd and explain why you chose the order you did. Discuss some of the problems these techniques might have. Remember to use your own words and avoid citing sources. Your main post should be approximately 200 words.

When responding to a discussion question, keep these guidelines in mind: - Use your own words to answer the question. Do not cut and paste from outside sources; do not cite anything. - Your main post is worth 60 points.

When replying to two students, keep these guidelines: - Respond to two different classmates, commenting on their posts with new, substantial ideas. - Do not just restate their points; add meaningful insight. - Choose students whose posts you either disagree with or can engage with meaningfully. - Each response should be at least 5 sentences or approximately 100 words and must include the responder’s name.

Responses are worth 20 points each, totaling 40 points. Be sure to include the first name of the student you’re responding to in your reply to identify it clearly. Late responses will be penalized, and the initial post is due by Thursday at 11:59 pm EST. Responses to classmates are due by Sunday at 11:59 pm EST. Use proper spelling, punctuation, and grammar; avoid texting abbreviations. Utilize the spell check feature in the response box.

Paper For Above instruction

In investigating a homicide scene, the order in which evidence collection techniques are employed is crucial for obtaining reliable and definitive results. I would prioritize collecting physical evidence such as fingerprints first. Fingerprints are quick to collect, non-invasive, and provide immediate leads since they are unique to individuals, thereby helping identify suspects or victims rapidly. Next, I would focus on gathering DNA evidence. DNA analysis provides highly specific individual identification, though it requires more time and laboratory processing. It is especially valuable when fingerprints are unavailable or incomplete. Finally, eyewitness accounts would be considered. Eyewitness testimony can be subjective and prone to errors such as memory biases or misidentification, but it can provide crucial context or corroborate physical evidence. The main challenge with fingerprint collection is potential contamination or smudging, which can compromise accuracy. DNA evidence requires meticulous handling to prevent contamination, and its processing can be time-consuming and expensive. Eyewitness accounts may also be unreliable due to stress or memory decay, limiting their evidentiary value. Thus, the chronological approach prioritizes swift, tangible evidence collection while acknowledging the limitations inherent in each technique. This sequence aims to maximize evidence integrity and investigative reliability, ultimately enhancing case resolution.
