Module Nine: Lab Questions


















1. Which technique is the best choice when blood is found at a crime scene? In the genetics laboratory (under "resources" at the bottom of the window), who is one individual that contributed to modern genetic analysis? What did this person contribute? Analyzing the blood in a lab would be the best technique, Alec Jeffrey’s is known as the father of genetic profiling. He invented what is now an essential technique. Also he linked a murderer to two young girls.
2. How are computers used in fingerprint analysis?
To match fingerprints from the case to cases in the past to determine who kill/injured a person at the crime scene. There are not fingerprints for everyone on file but there is a good chunk of people whom have been fingerprinted through a crime or something as simple as custody of children.
3. Who is a pioneer in fingerprint analysis? Describe a famous case that this person was involved in.
Edward Foster is the pioneer of fingerprint analysis, Foster testified as a fingerprint expert in the Jennings case. The fingerprints left in the wet paint next to the body and that proved that Mr. Hiller was the murder.
4. What is the role of the forensic chemist in crime scene investigation?
Forensic chemist detect substances such as drugs and alcohol. Also they can detect the composition and nature of the substances.
5. Who helped pioneer forensic chemistry? Describe one of her famous cases.
France McGill , She found a large sum of poison in an elderly couples stomach after they had died on christmas day.
6. In the ballistics laboratory, what is the water tank used for? Describe the analysis. To determine whether a bullet found at the crime scene and whether it actually came from the suspects weapon, it must be compared with another bullet from the same gun.

    Once the blood sample is isolated from all other organic material DNA is extracted from its biological source material using a hypotonic chemical buffer and being centrifuged. The extracted DNA is then measured to evaluate the quantity. After isolating the DNA, specific regions are copied with a technique known as the polymerase chain reaction, or PCR. PCR produces millions of copies for each DNA segment of interest and thus permits very minute amounts of DNA to be examined. The resulting PCR products are then separated. The separation methods used today include slab gel and capillary electrophoresis. Fluorescence detection methods have greatly aided the sensitivity and ease of measuring PCR-amplified samples. The specific methods used for DNA typing are validated by individual laboratories to ensure that reliable results are obtained and before new technologies are implemented. Samples are then compared to each other as well as DNA databases which are a valuable tool and play an important role in apprehending criminals that have committed a crime before.…

    When investigating a crime scene, many different variables are taken into account such as fingerprints, any other forms of DNA, or even clues left behind at a crime scene. Even looking at blood splatter, the forensic technician can conclude an estimated guess to the weapon used, the height of the person, whether it was foul play or not, and even if it was passive patterns or projected patterns. Blood splatter analysis becomes important when recreating a crime scene (Peschel). Bloodstain pattern analysis comes into play; and that is the interpretation of bloodstains at a crime scene in order to recreate the actions that caused the bloodshed (“A Simplified Guide”).…

    The forensic Scientist cannot exclude their of them from the crime scene profile. The suspect has a higher probability of being involved in the crime compared to other possible suspects (1). Furthermore if both individuals DNA is found, the forensic scientist can conclude that there is a possibility of rough play, or physical interaction between the two individuals(3). This information can then be built up, by comparing any possible bruises or marks, and using the other evidence found at the crime scene to build a strong suspect and crime scene…

Furthermore, the gruesome was preserved enough to draw a sample of DNA and fingerprints.…

    The current methods of fingerprinting that involve subjective comparison and matching of fingerprinting has led to disapproval of the method. Extensive testing has shown that the results of fingerprint testing are not valid (Schmalleger, 2011). Fingerprint matches are now being done by experts, those fingerprints that have been previously been examined to make identification of suspects were presented to the same experts in a different context and the results were different. Similarly, DNA evidence for identification of criminals has been marred by several problems. Surreptitious DNA collecting, presentation of partial DNA profiles, and fake DNA evidence; cast doubts on the DNA evidence presented in courts (Schmalleger, 2011).…
