    There are only three basic patterns and they are loops, arches, and whorls. Loops cover about 60-65 %, whorls cover about 25-30 % and arches cover 5-10% of all fingerprints. These classifications can be divided even further like plain and tented arches, or radial and ulnar patterns. An example would be that an examiner found a set of fingerprints on a glass. Now they will be able to compare the prints to see if it has the same print pattern as the offender, which is a loop pattern. The loop pattern is a fingerprint class type, along with the arch and…

    In 1892, Francisca Rojas was found with intense neck injuries while her two sons were found with their throats cut open and dead. Francisca Rojas fanatically accused her neighbor who, under extreme interrogation, would not confess of committing murder and injuring Rojas’s neck. Inspector Alvarez, the head of the case, went to the crime scene and found a bloody fingerprint next to where the boys laid. After comparing the fingerprint to those of the neighbor, mother, sons, and other suspects, Alvarez deduced that it matched the mother’s right thumbprint. She then confessed to the murdering of her sons. The discovery of the print saved an innocent neighbor from harsh punishment. Fingerprints help solve crimes and save people's lives everyday. For that reason, it is important for people to understand fingerprints significance.…

    When investigating a crime scene, many different variables are taken into account such as fingerprints, any other forms of DNA, or even clues left behind at a crime scene. Even looking at blood splatter, the forensic technician can conclude an estimated guess to the weapon used, the height of the person, whether it was foul play or not, and even if it was passive patterns or projected patterns. Blood splatter analysis becomes important when recreating a crime scene (Peschel). Bloodstain pattern analysis comes into play; and that is the interpretation of bloodstains at a crime scene in order to recreate the actions that caused the bloodshed (“A Simplified Guide”).…

    Advancements in forensics science and DNA technology has revolutionised our ability to solve crimes, subsequently helping to develop clear and concise investigative processes. The discovery of DNA and methods of identifying individual genetic imprints such as Familial Searches has allowed more sophisticated analysis which has advanced since the Colette Aram case. Identification of DNA is vital when identifying and convicting suspects or even exonerating individuals. Thus, having an accurate system of DNA identification has been an essential discovery of the 20th century (British Medical Association, 2012). This paper will examine the limitations encountered while investigating the Colette Aram case, subsequently analyzing the advancements that…

    Lattes has impacted forensic science tremendously. By discovering that blood could be organized into different groups and could be used to identify a person has made it easier to find suspects today. Sir Alec Jeffreys is a geneticist from the University of Leicester in Great Brittain, not quit in the forensic science field, but he has impacted forensic science forever. One day he realized that he could use DNA to identify people while studying x-ray images of a DNA experiment he was running in his lab. At the time he was focusing on methods to resolve paternity and immigration disputes. While analyzing the DNA he discovered the repetitive patterns of DNA that are now known as Variable Number of Tandem Repeats (VNTRs) ended up discovering that they were present in all humans but they all vary in length for each individual. He realized that this variation could be used to find out the identity of a person. He called this “genetic fingerprinting”. Mathieu Orfila, also known as the “father of toxicology”, published a treatise on the detection of…
