How Dna Technology Are Used in Solving Crimes?
"I am strongly optimistic that enhancing the generation and the use of DNA information and analyses will contribute greatly to the field of criminal investigation and in effect, downgrade with expediency the crime rate in the country," Angara said. What are those for?
DNA matching will become an ever more powerful weapon against crime. Law enforcement will increasingly be able to identify suspects from biological evidence at crime scenes, saving investigative time and protecting innocent people from suspicion. When DNA evidence is properly handled and stored, it is well accepted by courts, and used to convict the guilty and free the innocent. There were different ways in solving crimes and identifying the correct suspects. This includes estimating time of death, forensic entomology, DNA profiling, analyzing blood stains and doing some autopsy. (Nicholson, 2012) But, which of this ways is the most accurate and which can give an unbiased result? The past decade has seen great advances in a powerful criminal justice tool: deoxyribonucleic acid, or DNA. DNA can be used to clear suspects and absolve persons mistakenly accused or convicted of crimes. DNA can be used to recognize criminals with incredible accurateness when biological data exists. Therefore, DNA technology is increasingly vital to ensuring accuracy and fairness in the criminal justice system. DNA is generally used to solve crimes in one of two ways. In cases where a suspect is identified, a sample of that person’s DNA can be compared to evidence from the crime scene. The results of this comparison may help establish whether the suspect committed the crime. In cases where a suspect has not yet been identified, biological evidence from the crime scene can be analyzed and compared to offender profiles in DNA databases to help identify the perpetrator. Crime scene evidence can also be linked to other crime scenes through the use of DNA databases. (Osuna, 2011)
