Cover Letter After analysis and individualization of our evidence, we concluded that Talia Zagon killed Mr. MacDougall. To determine Talia Zagon was the murderer, we performed many tests in order to analysis and individualize the evidence. We had known samples of hair, fingerprints, handwriting, paper, ink, blood, and fiber from the five possible suspects. To compare these samples, we used the unknown evidence from our crime scene. The first test we performed was the fingerprint test.
Forensic biology will provide critical leads concerning the people who committed the murder. By examining the DNA evidence obtained from the crime scene, the law enforcement officials can be able to identify the suspects (Kayser, 2017). Identifying the suspects will require the law enforcement officials to match samples of possible suspects with those obtained from the crime scene. A non-match could be a strong indicator that the suspect was not involved.
like if the samples gathered from a crime scene may give a positive results with the DNA of a suspect. This could be used as proof that the suspect had been available at the crime scene – yet it doesn't say that the suspect carried out the crime and did the wrongdoing thing on the place of the investigation. DNA proof alone is not enough to solve a crime It is most valuable when put close by other confirmation, for example, fingerprints, foot shaped impressions, wrongdoing scene examination and observer accounts. Other biological proofs might be gathered, like blood splash examples (demonstrating the direction of the damage) and microbial data (which may give pieces of information as to the time of death). DNA databanks In New Zealand there is a databank of DNA profiles.
I feel that DNA is the only reliable forensic tool because its principles are example of real science. Mentioned in the video, forensic science was developed by law enforcement, but DNA analysis was developed by medical science. A much more reliable source. There may be certain situations where DNA isn’t the best tool to go off of. Like for example if there isn’t an enough quantity of it at the scene of a crime or if it has been mixed with someone else’s (Kaye and Sensabaugh, 2000).
Brenton knew very well what he was doing, but he felt that he needed to falsely confess to get himself out of the interrogation room. Thanks to scientific advances, we are now able to analyze DNA taken from crime scenes. This is significant because it enabled the wrongfully accused to prove that they did not commit the crime for which they falsely confessed. In 2004, Drizin and Leo studied 125 of these cases to determine the causes. Physical and psychological coercion have been found to induce false confessions, especially in children.
Also in that room was a drug locker each one had new evidence of collected for the recent drug bust. All of the evidence was put in brown paper bags with the officers’ name and an evidence label on it. Officer Dewey took out one of the bags out that had his name on and opened up for testing. Even though they had already known that the drug in the bag was marijuana he offered me to perform a color test. Upon seizing the evidence, the officer should perform a Duquenois-Levine color test on the suspected plant material.
Importantly, criminal profile maybe misleads police. It maybe allow the criminal to escape detection, police cannot arrest the offender as soon as possible. It will let an innocent person may be dead as a result. One of the case in Hong Kong in 2006, the offender Tsui Po Ko, he was a police constable in the Hong Kong Police Force. He was commit bank robbery and murder.
This was to tell the police that this was an act of satan. The fifth piece was the same shoe print at another crime scene. The police thought they were trying to bait him, but it turned out that this was a pretty big piece of evidence. The sixth piece was the car he had been driving with one of his fingerprints on it. This time they had a new and improved
This process takes about four to six hours to complete. The swabs and photographs becomes evidence, which is collected and preserved in a sexual assault evidence kit, commonly referred to as a rape kit. “When the rape kit is tested, the DNA evidence contained inside can be an incredibly powerful tool to solve and prevent crime” (End the backlog). “The DNA inside the rape kit can help identify an unknown assailant and confirm the presence of a known suspect” (Hansen, 2011). It
The forensic scientists would apply the principle of blood spatter analysis. Blood spatter analysis is the interpretation of bloodstains at a crime scene in order to recreate the actions that caused the bloodshed. By using the analysis they observe the spatter of the blood, the investigators and forensic scientists can determine how the victim was wounded, what weapons were used and where the object hit the body. Evidence is really important because it can be either stopping the criminal or letting him
