Analysis of Paper Documents
The scientist from CSI explains that when the pen enters in contact with the paper, one part of the ink remains on the surface but the lower layers of the paper absorbs the other part. It allows scientists to recover what was written in a paper that was in contact with water, as example used in the episode. To analyse evidence like this it is necessary to do a procedure with Multi-spectral imaging system (United Nations Office on Drugs and Crime 2010), using equipment as a light source, a stereomicroscope, a magnifier, an UV light source and a VSC2000 Video Spectral Comparator (Virginia Department of Forensic Science 2012). Firstly, it is necessary to conduct a visual exam using natural or artificial lighting. Then,

The sample can be collected with a tape, swab or even scraping and cutting objects (Williamson 2012). Then, a Polymerase Chain Reaction (PCR) is done to increase the number of genes (Houck & Houck 2008). Next, the sample is mixed with fluorescent compounds, which attach themselves to 13 specific locations in the DNA, finally giving a specific genetic profile of the person (Houck & Houck …show more content…
The material was suggested as motor oil. Then, the team analysed the motor oil of each motorcycle. They also explained that each motorcycle would generate specific motor oil because besides the components of each oil varies from branch to branch, each oil will contain particle of iron zinc from the motor of the motorcycle itself. After the collection, the team analysed the samples in an Inductively Coupled Plasma Mass Spectrometry.
In ICP, the sample goes through a peristaltic pump into a nebulizer where it will be broken into an aerosol of small droplets by a fast stream of argon gas. Then, it will pass through a spray chamber, eliminating larger droplets, going to the quartz plasma torch. The plasma will ionize and excite the atoms, which will emit light from their ions, which in turn, will passes through the monochromators, separating the light into many wavelengths. The light then will reach the charge-couped device (CCD) detector (Wolf
Obtain a scintillation vial and label it using tape and a pen. For this part of the lab, make sure to record the mass of the empty vial using a digital scale before proceeding. Now, obtain 0.100 g of the same unknown substance and place into the vial. Record the exact mass again and be sure to take note of any crystal formation that occurs.
In Season 1 of CSI: NY, “Three Generations is Enough” focuses on two murders that happen to be connected. The episode starts in a stock trading building where a suitcase is found unattended. The room is cleared and investigators analyze the suitcase, matching the fingerprint on the suitcase to a database. When they get to the apartment, they find it has been ransacked, presence of metal shavings, a degasser, and a computer that has a missing hard drive. Later, another detective finds a suspected suicide in front of a church. Next to the body, three cigarette buttswere found, and when they search the church, they find a candlestick, part of a tooth that came from the victim, and a letter. After questioning potential witnesses, detectives eventually find a burned car that has the body of the stockbroker inside of it. They also find a gun, the missing hard drive and a burned piece of paper. When they analyze the hard drive, they find an email from the victim from another person, Charles, about an argument right before the death took place. The piece of paper in the car indicated where the car had been prior, and they search the location, finding money and a device used to make bullets, linking the location to the metal shavings found in the apartment.
The CSI Effect began to fully take effect as the popularity for crime scene investigation televisions series became popular. One of the more prominent television series that contributes to the CSI Effect is CSI however there are several more like Criminal Minds, Bones, or Castle. In 2006 the weekly ratings taken by Nielsan determined that “five of the top 10 television programs [during one week] were about scientific evidence in criminal cases. Together, they amassed more than 100 million viewers” (Shelton, 2008). This fact emphasizes just how popular crime television is but more important what this fact shows is that more than 100 million people can be affected by the CSI Effect.
In the episode “Gum Drops” of the series CSI: Crime Scene Investigation, one of the featured forensic analysts was a crime scene investigator. The duties of a crime scene investigator are diverse, and include tasks such as securing and processing the crime scene, documenting the crime scene with photography and investigative reports, giving testimonies in court, and collecting evidence for analysis in forensic laboratories.
Everyone throughout time is responsible for every move that the certain person makes, whether or not that this person is pushed to make a decision that he or she makes. Once that person decides to be pushed by another person, any move that the person makes from that point on has become their personal responsibility. In William Shakespeare's, Macbeth, Macbeth is pushed by many different characters and feelings. It is believed that Macbeth is not responsible for actions that he makes throughout this play, except every move he made was ultimately decided by himself. Whether it be prophecies, or instructions given by his overbearing wife, he made the decision to be controlled.
The purpose of this project is to provide the reader of this paper with a descriptive analysis of an episode of Crime Scene Investigations (C.S.I.). The intent is to show what is provided by the television series of what happens in a crime and what is supposed to happen during a crime scene investigation. The reader should be able to understand during this analysis to what in fact is non-realistic in this television episode and what is reality as determined by what has been researched. This will show what really happens in a crime scene investigations lab.
The CSI effect is “the phenomenon in which jurors hold unrealistic expectations of forensic evidence and investigation techniques” (The Economist, 2010). This phenomenon stems from the crime scene television shows. In recent years, crime-fiction television series have become more popular. These shows include CSI: Crime Scene Investigation, and Law and Order. Similarly, forensic dramas have gained popularity over the years as well. These shows include, Without a Trace, Bones, and Cold Case, approximately 100 million people watching these types of show on a regular basis. Due to the popularity of these shows court officials have become worried about what types of expectations jury members will have of court and trials (Shelton, 2008). Another
The CSI effect is the phenomenon in which jurors hold unrealistic expectations of forensic evidence and investigation techniques, and have an increased interest in the discipline of forensic science because of the influence of CSI-type television shows. This effect includes raising the state’s burden of proof because of jury expectations that forensic evidence should always be discussed at trial, and the belief that forensic evidence is never wrong. The show CSI: Crime Scene Investigation provides inaccurate information by closely relating to the reality of the investigation, but accelerating and exaggerating long processes in the criminal justice system. For example, searching databases for fingerprints and other DNA evidence can take months, whereas in the show it takes only minutes or hours. Also, an increase in demand for forensic evidence for a conviction has placed a higher burden of proof on the prosecutors.
Investigating a crime can be a hard process but with the knowledge of CSIs, it’s good to know that they can get the job done by solving a crime and getting justice. Sometimes certain things are not what it seems like on TV but at least we can get a idea of what CSIs do and what they deal with when solving a crime. Being that the CSI: Crime Scene Investigation show is popular , they do a good job with portraying what real CSIs do in reality while solving a crime.
The process of DNA fingerprinting in humans involves the replication and arrangement of extracted DNA, to create a pattern/fingerprint that is viable for comparison. This process involves the application of DNA extraction, digestion by restriction enzymes, Polymerase Chain Reaction (PCR) and gel electrophoresis. This results in a DNA profile with bands of varying widths that can be used for the comparison of genetic information. DNA extraction occurs in three stages. Firstly, a
