DNA testing was introduced until the 1980s, so the DNA could not be used on this hair to positively identify it as belonging to either of the two victims. So, it should not have been said that the hair belonged to the victims as that could not be positively determined without DNA…
The author Saferstein (2014) delineates DNA test that was used to identify JonBen`et killer one year the later. The author Saferstein (2014) defines this newly introduced DNA testing chapter Fifteen Entitled DNA: The indispensable Forensic Science Tool. This DNA testing is defined as “Touch DNA.”…
The term "forensic" means "in open court"(vocabulary.com). Forensics is a broad array of sciences used for both legal and criminal purposes. Help to solve crimes using analysis of physical evidence compared with evidence with suspects. A Forensic science technician or also known as, forensic scientist, crime scene investigator, or Criminalist, is responsible for collecting, analyzing, and preserving physical evidence to aid in investigations. The contributions they make to today's world can seem in many ways unnoticed, but they are a crucial part of any functional judicial system or society.…
The Houston Forensic Science Center is a local government corporation for whom I would like to work for in the future. Their mission is “To receive, analyze and preserve physical and digital evidence while adhering to the highest standards of quality, objectivity and ethics.” Their headquarters are currently located at 1301 Fannin St, Suite 170 Houston, TX 77002. However, none of that was always the case. Due to several severe issues the HPD was experiencing with its forensic divisions, the HFSC started to govern the Houston Police Department’s forensic operations, previously located at 1200 Travis St., on April 3rd, 2014.…
Introduction: It was a hot summer morning in 2012. A 911 operator received a call at 9:45 am from a man. He reports being worried about his next door neighbor, a 38 year old hispanic woman named Anna Garcia. He informs the police that the last time he had spoken to Anna was the previous morning at around 6:30 am. He reports seeing her wear a sweater when they were experiencing a heat wave that day.…
When it comes to criminal trials, there are many important pieces of evidence. Forensic Science: Evidence, Clues, and Investigation by Andrea Campbell, explains that forensic evidence uses sources such as fingerprints, hair particles, and mainly hard evidence. The story also explains that there are a couple downfalls when using this evidence. One main downfall falls heavily on the investigators who handle the substances. Even though they’ve collected hard, substantial, evidence, it is hard for the jury to trust the hands that dealt with it.…
In recent years, television shows such as CSI and NCIS have placed science in the spotlight, frequently depicting forensic science as some type of futuristic magic, unravelling crimes within an hour and without error. Of course, these shows are only fiction. One forensic scientist estimated that “40% of the science on CSI does not exist, and most of the rest is performed in ways that crime lab personnel can only dream about” (Winter & York, 2011). With more than 90 million people watching crime-related shows every week, it is not surprising that the effect of their popularity has become evident in the real world, specifically in real-life criminal trials. Science is bow thought of as a method of catching and convicting criminals, and forensic investigators are basically the heroes who are capable of…
My results showed that the blood type found at the scene of the crime was A positive. The test also proved that Ralph Voosen and Brian…
The advancement of forensic science has progressed immensely since its conception. The contributions it has made for the legal system are immense. One such example are its techniques used to extract DNA during forensic cases. DNA is considered to be one of the most well regarded and highly assessed sources of information (Gershaw et al., 2010). Another important development used during investigations is CODIS or the Combined DNA Index System.…
The period of c1886-c1926 saw great changes in investigative methods and thus lead to huge development in policing and how crime was dealt with. Such changes include the creation of the CID, and have shown to have more significance than others. For example, the introduction of forensic science enabled police to convict criminals in multiple cases, such as George Joseph Smith and Dr Crippen, rather than the use of telegram which only showed major significance in the Crippen case. A great flaw in 19th century policing regards the very few investigative methods available to detectives at the time.…
With the case of the Baltimore crime lab, it was revealed that the lab analysts were contaminating evidence with their own DNA, as they did not put their own DNA samples into the system. Their DNA thus becomes a…
Many different things could go wrong while analysing DNA, such as cross-contamination. Ira Flatlow discussed in an interview that “sampling techniques are changing, so the standard for using DNA evidence should be changing, too.” At a crime scene, you could find fibers, hairs, and maybe even blood that has absolutely nothing to do with the crime that was committed. Someone could use things that has a person’s DNA to plant at a crime scene and have them framed. As crazy as it sounds, it happens.…
Stoiloff supported the need for scientific integrity and support for forensics. She has also emphasized the need for resources to help create new forensic technologies. She explained the importance of higher education in forensics and that the media portrayal of forensics is misleading and even wrong at times. Her testimony also spoke to the need of leadership as well as funding for the forensic community. The amount is large, congress has allocated one billion just for DNA backlogs so much more would be needed to truly make the forensic discipline better in all the areas needed.…
1. Fire scenes are different than the regular crime scenes because as for the evidence of a fire scene was most likely destroyed or burned, the person who committed the crime does not usually the crime scene. This makes it a little more difficult to piece together the suspect and convict someone of their crimes. 2. The blast effect is what happens when a rush of gasses from the source of the bomb blows outward.…
There are several reasons that this occurs, and there are several ways to correct this life changing problem. This includes misidentification. This is a huge problem that leads to wrongful convictions. DNA evidence mishandling and tampering also help to convict innocent individuals. Lab technicians that are undereducated in handling, analyzing and interpreting DNA evidence is another major problem…
