Fingerprint recognition

In the United States, both blood type testing and DNA fingerprinting are legal, though forensic investigators spend no time getting blood types because of how useful DNA fingerprinting has become. In 1989, the Virginia Division of Forensic Sciences was the first to start implementing DNA testing in criminal investigations (10). At first they had policies only requiring certain classes of offenders to submit DNA samples to be included in a DNA database, however, not even a year later, they…

On October 14, 1981, during the Civil War in El Salvador, three brutally tortured dead bodies were found in El Salvador's main dump site. Two of them were brothers, with the last name Escobar. Salvadorian military officers thought these Escobar brothers were the ones who had committed robbery in various towns. One of them, Jorge Escobar, was my grandfather. This type of heinous crime where three innocent men died is the reason why I am a Forensic Scientist and ultimately shaped my decision to…

DNA fingerprinting is used in forensic science to convict or exonerate a defendant of a crime. During an investigation, crime samples are collected from a scene or from a victim that can be used for DNA testing. Samples could include hair, blood, semen, or skin. After collection, these samples are tested for their molecular characteristics because the purpose is to identify the polymorphic DNA locations of one’s genes. This is because everyone has different genetic variations and can be…

performed was facial recognition on the video feed taken from the grocery store. According to Bonsor & Johnson (2001), with facial recognition computers can track landmarks of a human face on images and discern where the face is. It can then go on to try to compare those landmarks to pictures stored in whatever database that facial recognition software is connected to. In this case, detectives on Motive had the footage from the grocery store ran through their facial recognition software and…

The American Academy of Forensic Sciences is a professional website that was founded in 1948. The purpose of this American Academy of Forensic Sciences community is to provide information towards leadership of science, and the knowledge about the legal system. This community was developed to inform and educated everyone about their knowledge about this program, and to help them gather information on that specific subject of forensic science. It is searching for people that will join their…

of the trace and transfer evidence may be viable for matching depending on the care taken by evidence collection personnel, as well as forensic technicians, and if there is a match in the database. Some matches could be made years later when new fingerprints or DNA are entered into the database for comparison. DNA is the most trusted evidence in forensic history. Forensic serologists study chromosomes in the blood, saliva, or sweat that differ from each individual and can convict suspects and…

There are thousands of jobs that involve chemistry, and some people do not even know it. From something as blatantly obvious as a chemist itself to something in the agricultural field such as an agronomist. It may seem like the two may not have any correlation to each other at all, but both of the careers involve chemistry. Many people see forensic science technicians as some really cool crime scene investigators, but there is so much more to it. Forensic science technicians are crime scene…

John Zarka Mr. Kirby Forensic Science March 22, 2016 Shoe Print The basic theory behind footwear analysis is that, much like fingerprints, shoes may leave behind either prints (referred to as "imprints") or impressions that can be examined by investigators. The type of evidence left behind depends largely on the type of surface traveled. For example, a shoe will leave an impression in loose sand, but on a hard surface like concrete or linoleum, it will leave an imprint. These imprints or…

So you just finished watching an episode of Bones or CSI and now you are wondering how you can get a job in forensic science. Or, even better, you've developed a passion for problem solving and a love for the natural sciences and the scientific method, and you'd like to find a way to use that knowledge towards fighting and solving crimes. If this describes you, then a career in forensic science will probably be the perfect criminology career for you. The term "forensic scientist" does not…

There are several ways to find the criminal of a crime. For example, there is testimony, direct, and forensic evidence. But, only one will give the truth of the crime. This type of evidence would give truthful evidence that none of the other evidences can give a person. In the passage “Forensic Science: Evidence, Clues, and Investigation,” by Andrea Campbell, the best evidence to get through a trial is forensic evidence. Forensic evidence is evidence that is found in the crime scene, this…
