us, anything that escapes the body has DNA on it. Jeffreys had no interest in murder cases and crime, but two years later, the police were coming to him. Ten miles from Jeffreys’ laboratory, two 15-year-old girls were raped and strangled, the rapist/killer left no fingerprints, the only evidence the police had was the semen that was left on the girls’ clothing. The murders happened three years apart, but was assumed to be the same killer. Jeffreys tested the semen, and informed police that they…

DNA fingerprinting was discovered on September 10 1984 by Alec Jeffreys. His team at the university of Leicester had been working for seven years to see if it would be possible to tell people apart and whether they were related by using their DNA. They had been looking at regions of the human genome called VNTRs which stands for variable number tandem repeats. These can be thought of as a repeating string of genetic letters or basis, a bit like the same word written down many times along a line…

Picture this: A male forensic scientist just received a call to examine a crime scene with a dead body, possible homicide. At arrival, he discovered variations of individual evidence—some of which included multiple sets of latent fingerprints and a blood spatters—that could lead to a possible suspect or even the culprit responsible. Immediately, the forensic specialist begins to powder, lift, and collect the evidence. Considering the value of the individual evidence found—as D. P. Lyle stated in…

Introduction DNA profiling, also known as genetic fingerprinting is a method used to identify and evaluate genetic information/DNA in an individual. It is common knowledge that each individual (excluding identical twins) has a unique DNA sequence which makes DNA profiling the most appropriate method of determining paternal relationships and solving crimes. DNA samples can be analysed to produce a DNA profile which can be used as evidence in criminal investigations when matched to samples of…

system is because of Juan Vucetich was a police officer who created the first fingerprint system while working on a murder case. Mr. Vucetich invention was the start of something that is still being used till this day. Almost a century later Dr. Alec Jeffrey identified family groups in biological material. His discovery led to then use of DNA that would help solve crimes with little to no DNA evidence at all. With just these two alone have affected the practice of criminal law in major ways…

The past decade has seen great advances in a powerful investigation tool: DNA. Being DNA is found in every human being, every person's DNA pattern is one of a kind and except for identical twins, no two people can share the same DNA pattern. During a criminal investigation when biological evidence exists, DNA evidence can be used to identify criminals with incredible accuracy. Likewise, DNA can also be used to dismiss suspects or exonerate individuals mistakenly convicted of a crime. Ultimately…

during investigations are ever changing and evolving. For example, the discovery of DNA is only very recent within the last Century. Furthermore, genetic fingerprinting using a person’s DNA in forensic science was only invented in 1985 by Sir Alec Jeffreys at the University of Leicester. The impact that this still relatively new discovery/invention has had upon the investigation of crime in today’s society is huge. I thoroughly enjoyed reading ‘The Blooding’ by Joseph Wambaugh not only because…

DNA Profiling Introduction DNA profiling is a scientific process that was founded in 1985 by a Leicester University Geneticist Alec Jeffreys. DNA profiling can be defined as gathering tiny amounts of genetic materials from a sample of blood which belongs to one individual and using it as a method of identification via biological analysis. One of the methods used in DNA profiling is Polymerase Chain Reaction (PCR) Which is a 3 step process used to amplify small segments of DNA. Firstly the DNA…

On April 25, 2016, Darryl Pinkins walked out of the Lake County Correctional Facility in Crown Point, Indiana after spending nearly 25 years in prison for a rape he did not commit. Pinkins’ exoneration is the first instance of using the TrueAllele DNA interpretation system to prove innocence by reanalyzing mixed DNA evidence. In Pinkins' case, the DNA mixture evidence was found on the victim's clothes and had previously been inconclusive. DNA mixtures have been considerably difficult for the…
