QuestionQuestion

So far in this course, your study has been concentrated on the origin, developmental stages, and many uses of DNA to solve crimes. You have studied how various body fluids such as blood, saliva, and semen are tested, as well as identified the importance of mtDNA and nuclear DNA in DNA profiling. Below are several case studies that were solved using the procedures and analyses studied in class, and the application of the information obtained was used to solve the criminal investigation.

Choose only 1 of the cases listed below and explain how the physical evidence recovered from the crime scene was tested and analyzed to solve the crime.

A man and his wife were on vacation in Paris. On the way back to the hotel, they were approached by two men with weapons who demanded their jewelry. A physical interaction occurred in which the robbers violently wrestled the man to the ground and removed his watch and rings while his wife tried to run away. The man and his wife were shot and killed. The bodies of the two victims were pulled into an alley. Multiple scratches were on the body of the male victim, and blood was also found on the female victim because the robbers tore the necklace, rings, and earrings off that she was wearing. The two men committing the crime both had previous records for assault and robbery. How were the men convicted of the crime?

DNA Profiling
Abstract
DNA profiling is a forensic technique that identifies individuals following their DNA patterns that are unique to all persons. As explained, DNA profile is a minor set of DNA variations that are not similar to show how close individuals are genetically related. In addition, the DNA profile offers a comparison between the fluid and other DNA rich samples to compare with a pool of suspects. Since 1985, DNA profiling has been applicable in convicting and exonerating individuals from crime. For instance, if the theoretical build up indicates that a certain person committed a crime then it is rational to absolve individuals whom DNA does not match the crime scene DNA.

1. Introduction
In the recent decades, investigators have used DNA to convict criminals in cases where biological evidence is available from the crime scene. Unlike other forensic approaches of identification, DNA is more efficient as it offers an...
