Throughout the years technology has come an extensive way, resulting in the Criminal Justice System to improve their ways to catch criminals. One of these ways includes, DNA Fingerprinting. This reveals an opportunity for Crime Scene Analyst to have a greater possibility to capture criminals; a greater chance than DNA itself.
Alec Jeffery, discovered the differences regarding DNA in 1984 at the University of Leicester. Jeffery had attended school at Merton College and reportedly studied biochemistry and genetics, after his studies the individual decided to teach at the University of Leicester, the professor taught Genetics and was rewarded the name of Research Professor. Professor Jeffery has been awarded multiple awards for the following, …show more content…

DNA was discovered in the late 1980’s, by a scientist with the name of Alec Jeffery. The professor made the discovery of unalike DNA after noticing that each human being has distinct patterns of minisatellites. By the year, 1987, the first criminal was caught using DNA. This method is not only to catch the criminals, but to also prove the innocent. Scientists go through a series of steps to receive the outcome of DNA. DNA is simply a separation and recognizing elements within the pair. The method has multiple methods to determine result, however, their are four types of methods. RFLP technology is used, to the item containing the DNA, the process begins with examining the molecules containing the patterns, after this, a Southern Blout method is performed, this procedure, indicates repeating series. The second method of extracting DNA would include, Polymerase Chain Reaction, this procedure magnify specific sample; this procedure is mostly seen in smaller DNA samples, such as, paternity tests or limited amount of biological fluids. The third method, AmpFLp, is considered a relatively cheap and brief process. This method amplifies the human cells by using the PCR analyst. The fourth method, STR, is the most common type of method when determining DNA, however, this is known to have endless amounts of matches. This method examines the replication of base pairs on the DNA …show more content…

A teen by the name of Mary Sullivina, was found raped and dead after a recently arrival in her new home town of Boston. The attacker had raped an approxam. Eleven women before her and had got away with it, until, DNA came into play. This case was ruled a cold case, the town had a funding for reviewing cold cases. Due to this funding, the DNA that was collected from the scene--found on the victims body and a blanket located near the body-- was compared to a nephew of a suspect, the DNA showed a similar allies with the nephew, which indicated a man by the name of Albert DeSalvo was charged with the rape and murder of Mary Sullivan . The man was sentences to life in prison and years later he was stabbed to death by inmates. Thanks to the discovery of DNA Marys case--and many other individuals who have not had justice--have been solved.
A downfall to this innovation in technology, would be some “kinks.” Some individuals believe that storing DNA would be a violation to our constitutional rights as a citizen of the united states, this would only be a violent if DNA was taken without knowledge. If DNA was left at a crime scene, the analyst have evryright to examine the DNA. Another severe kink would include planting evidence. DNA evidence can show who the culprit is; unless the evidence is planted. The real suspect could try and plant evidence to convict the wrong suspect, DNA cannot determine
