Autopsy of a Crime Scene
1. Which technique is the best choice when blood is found at a crime scene? In the genetics laboratory, who is one individual that contributed to modern genetic analysis? What did this person contribute?
- The DNA Analysis Technique is the best choice because no two individuals have the same DNA. This makes it easy to determine a match between the person the blood came from and the blood sample. Alec Jeffrey’s came up with the first genetic profile in 1984. Jeffery’s invented the PCR, also known as the polymerase chain reaction.
2. How are computers used in fingerprint analysis?
- Computers hold hundreds of fingerprint samples that have been recorded through time. When a fingerprint is found, it can be run through the system to try and find an identical fingerprint and determine the owner.
3. Who is a pioneer in fingerprint analysis? Describe a famous case that this person was involved in.
- Edward Foster studied fingerprinting in the United States and eventually introduced it to Canada. Foster was an important part in founding the National Fingerprint Bureau. In 1911, fingerprints were found on a wall next to a murder victim, Mr. Hiller. Foster testified that the fingerprints on the wall were a match to Mr. Jennings who was arrested when seen fleeing the crime scene.
4. What is the role of the forensic chemist in crime scene investigation?
- Forensic chemists analyze all chemical, inorganic and organic aspects of a sample. They separate the components and identify them using a variety of tests and devices. The findings will be used to help solve the crime and as evidence in court.
5. Who helped pioneer forensic chemistry? Describe one of her famous cases.
- France McGill was a pioneer of forensic chemistry. One of her famous cases involved an elderly couple who died on Christmas day. After investigation, McGill discovered that the couple had consumed poisoned muffins made by their granddaughter. The
