Crime scene investigation
During this project we learned about the DNA, Blood typing, and how these thing play roles in criminal investigation. In our classes we were each assigned partners and then given a crime scene to investigate with our partners. There were a total of three crime scenes. One was investigation the supposed suicide of a older man. Another was a suspected vehicle homicide and the third was a investigation surrounding the finding of a human skeleton. My partner and I got assigned the latter case, We were unable to find the perpetrator of the crime.
During this project we learned about certain specific science and how they can help solve a crime. The 4 sciences that I learned about were; Mitochondrial DNA, Blood Typing, Forensic Anthropology and how to conduct an autopsy all together. Mitochondrial DNA is different then Nuclear DNA which is the DNA that you receive from you parents. Mitochondrial DNA is more often left behind at the scene of a crime and it identifies someones specific DNA but this DNA is also shared with family members so it does not always rule out all suspects. Blood type is the proteins that are either present or absent in your blood stream. These blood types define who you can give blood to and who you can receive it from. If the perpetrator of a crime leaves behind trace blood evidence you can often analyse this and find out their blood type and then compare it to certain suspects. Forensic anthropology can tell you the victims height and sex which can help identify who the victim is. Conducting an autopsy is just putting these sciences together to get results.
The most interesting science for me was Forensic anthropology. I found this so interesting because. I though it was cool to see the way you could find out who the victim was only using their skeletal system. I also thought that it was interesting to see the anatomical differences between male and female. Previously I did not know that there were such big differences in anatomy between male and females. Another thing that was cool to learn was how to find out someones height based on certain equations involving different skeletal body parts. Although I do with that I had been able to solve my crime scene. The fact that it was 3 years old did not help though.
