Each person has their own unique DNA that makes them different from others. The scientists had invented the DNA analysis procedures which helps to bring down the criminals due to the DNA that they left behind the scene. These techniques are collecting the DNA specimen and extracting DNA from the specimen. In addition, other areas such as immunohistochemistry (IHC) and forensic chemistry also help the investigators to complete their jobs. DNA analysis is also used to prove the relationship between 2 people such as mitochondrial DNA analysis and Y chromosome.
The crime technicians collect DNA specimen that the criminals left behind so that the specimen can be used for the process of extraction DNA by PCR and STR analysis. Then, DNA will be …show more content…
For example, there was a contaminated the evidence in the James Mixer cold case in 1969. She was beaten to death and left at the grave yard with her bloody panty hose over the body. During that time, DNA analysis was not invented. In 2001, the investigators used the DNA analysis to solve this cold case. Therefore, they tested the bloody spot on her hand and her panty hose with the convicts in the data base. The result came back with a match the suspect, John Davis Willis who killed his mother. He seems like to be good suspect for the investigators due to his violent crime. However, John Davis Willis was only 4 years old during the death of James Mixer. Therefore, the specimen was contaminated during the process of collecting, extracting, or analyzing procedures. In my opinion, these steps are so important to solve the crimes, …show more content…
Florence was pushed over the hail by her husband Mark and she fell on the concrete side of the boat. At first, the investigators thought this was an accidental case, but the medical examiner concluded that it was a homicide case due the protein that tried to repair after a severe head trauma. Therefore, the medical examiner used to IHC to test the protein in the brain and concluded that Florence was still alive while laid her face down on the concrete side of the boat before being punished to the lake, resulting her death. In my opinion, there are many other medical science aspects that we do not have any knowledge about, like IHC staining in this case. These areas are crash reconstructions experts, forensic chemistry, forensic behavioral science that also play important to help the investigators to solve the crime. Therefore, I believe these areas should be more introduced to the college students so that the students can have ideas what these fields are about or exist to apply for. In the future, we will have even more solid and bright team of experts in every field to help the investigators finding the murders. Although DNA analysis and other science fields bring the benefits to the forensic science, but it also benefits in proving the relationship between two individuals in some legal
