There are many techniques in the field of criminal justice that are used to solve cases. DNA testing is one of the best ways to solve cases. Each individual has their own unique DNA profile. Additionally, in this case, DNA testing proved that an innocent person did not commit the crimes. Additionally, I think Colin Pitchfork deserves life in prison without the possibility of parole. DNA testing is one of the basic techniques of forensic science. Everyone has their own DNA profile, even identical twins. DNA is present in every cell in our body. In the 1980s, a British scientist named Sir Alec Jeffery's developed DNA profiling. Our DNA can be separated from human cells found at a crime scene, along with sweat, blood, skin, hair roots, semen, mucus and saliva. The Colin Pitchfork case was the first murder conviction based on DNA profiling evidence. A fifteen-year-old girl named Lynda Mann was raped and murdered after disappearing from the grounds of Carlton Hayes psychiatric hospital in Narborough, Leicestershire, in November 1983. A semen sample was taken and shown to be It was a type in only ten percent of men. Additionally, the sample came from a person with blood type A. However, no suspects could be found. Three years later, another fifteen-year-old girl, Dawn Ashworth, was sexually assaulted in a similar way and strangled. This happened in a neighboring village of Enderby. Semen samples were taken and showed the same blood type. Seventeen-year-old Richard Buckland, with learning disabilities and working at Carlton Hayes Psychiatric Hospital, was spotted near Dawn Ashworth's crime scene and received new, previously unseen information about the body. In 1986, Buckland confessed to Ashworth's murder but not Mann's. Scientists used Sir Alec Jeffery's new technique... middle of sheet of paper ...... to testify before a jury. The jury discusses the evidence provided and makes a decision on which everyone must agree. The proof must be beyond a reasonable doubt. I simply cannot believe that people can be convicted of a crime if their DNA is not present during the crime. That being said, I feel that DNA profiling is an excellent technique to use to convict a guilty person for the crime they committed or to exonerate an innocent person for the crime they did not commit. In conclusion, I believe that my opinion is justified. because I can't believe our society can wrongly convict innocent people. Every human being is unique and does not have DNA like any other person. Forensic scientists use DNA profiling to help track down criminals. If no two people have identical DNA, I believe this is one of the most accurate ways to convict a criminal beyond a reasonable doubt..
