Forensic Evidence

Question one

Various ways can cause a plane to crash. Some of the factors that make a plane crash are not known by many. In this case, it may seem to be a difficult task, but it required more effort to ensure that all becomes a success. There are some of the things that need to be done to help determine how the major cause of the plane towards crashing. For instance, one does not need only to visit the site of the incident, but there various things that need to be done. Some of the things that will help one examine all the possible means that will help determine how the accident took place. One of the critical elements that will be required in this case is to collect all the portions of the plane. Once the portions have been collected from the scene, they will be taken to the lab. It is essential to ensure that the key things are not left from the site as they will contribute towards determining the real cause of the plane. They will then be required to be analyzed by the forensic engineer (Cohen, 2012). He will use the available tools from the crash site to acquire the necessary information concerning the major factors that contributed to the crash. One of the critical aspects, in this case, is the mayday recordings, which may determine everything. The mayday, in this case, will be analyzed using the voice print analysis. It is key as it will help determine and acquire the required information that led to the fatal crash. Another thing that will play a significant role in coming up with better results in the collection of the gasoline samples. The gasoline samples, in this case, will be required to be collected and analyzed by a physical science unit. They will use this information to try and determine what may have led to the crash of the plane. These are the two key things that need to be focused on helping determine why the plane crashed on the farmhouse. The pilot may have also caused the crash. The pilot may also contribute towards the crash of the plane. But in this case, we need to focus on physical things that will help determine the real cause of the plane crash and what may have contributed. The forensic team will work hand in hand to assess all this.

B.

In this case, it is difficult to determine some of the essential aspects such as the number of people in the plane and the farmhouse. Whenever a plane crashed, one cannot determine the number of passengers on board. It may require one to refer to the airport on the number of people that boarded the plane. But in this case, the aircraft was believed to be transporting members of the Mexican gang. No one was certain on the number of people that were on that particular plane. It was also challenging to determine the number of people that were in the farmhouse. The only thing that can help resolve this case is through conducting a forensic. Here the forensic team will be required to visit the scene where they will collect information (Kvaal, 2006). They will receive the remains of the people from the plane. It will not be an easy task of collecting the remains from the scene. The team should conduct a better analysis first of the location and survey on how the event took place. Here, the forensic team will take their time to understand the location first before starting to collect the evidence.

The evidence will play a more significant role as it will be essential to determine different DNAS to determine the number of people that were present in the farmhouse and the plane. The will collect the information and present it to the forensic odontologist. The odontologist here plays a vital role as he will ensure that he analyses the data that has been achieved from the site. His will first start by differentiating the remains that have been collected from the field. Hence it will be easy to conduct the analysis. He will use the tissues that have been collected from the crash site. He will work for hand in hand with the biology unit. The biology unit here is the key to everything as they will be able to tell which sample belongs to who. The forensic team only presents the data in the manner that it will be analyzed without any difficulty. The first thing that will be determined by the biology team is the blood type of the samples that have been collected. After the blood type has been differentiated in different parts, the next thing is to conduct a DNA. The DNA will help come up with information about each patient.

C.

The other thing while conduct a forensic on the plane is to determine what was being carried in the flight. Despite holding a forensic on the humans, the other thing is to determine the kind of cargo that was on the plane. In order to make it successful, the forensic teams need to visit the site where the plane crashed and collect remains of the cargo. They will try to manage each and every information that is available at the moment. The information will then be moved to the lab, where it will analyze to determine what was contained in the plane. Since the police suspect that the plane was carrying drug loads, then there is the likelihood that they had drugs with them. The police then must determine whether it is through they had drugs with them. The samples of materials collected from the field will be presented before the physical science unit. This unit plays a significant role in identifying some of these things. There are the ones who have the power to conduct a better analysis on different types of drugs. The other thing that will be analyzed in this case is whether there was any presence of firearms. The firearms will be examined through the physical science unit. We can also determine the fact that the forensic team has expanded on how they conduct their investigation. For instance, they have advanced in the use of fingerprints.  It is more efficient to use fingerprints in any case as it will determine the kind of people that were involved in a specific type of crime. They also use the comparison microscope in conducting their forensic investigation. The comparison microscope is used to determine various objects used in a crime. For instance, they will be sued to determine the kind of firearms that were in the plane. With this, it will be easier for the forensic to decide on the type of gun by the criminals (Taylor & Skene, 2003).  Another critical concept, in this case, is the use of DNA in conducting forensic. DNA will help identify anything no matter how bad it is, for instance, anyone that has been burnt and turned into ashes. There is also the sued of toxicology and the crime and crime scene unit. They help a lot in speeding up the process of forensic.

Conducting an investigation is one of the essential aspects of the forensic team. The investigation will open doors to many things. The forensic team will be able to determine different kinds of events that took place in the crime scene. They will have the required knowledge of how various things will be conducted towards coming up with evidence concerning a particular crime. In the process of a crime scene, one of the key things that need to come up with comprehensive evidence is through focusing on the death investigation. Through death investigation, it will be easier to determine how a particular crime took place, leading to the death of some people. In the crime scene, some things need to be resolved first before anything else. The first thing is to protect the view of the crimes in the manner that it will be not be contaminated by anyone. The team will be able to maintain the integrity of the scene where they will be able to block the surrounding from invading the stage. The evidence that will be conducted will be essential as it will be used in the court of law. But in the case where the analysis is undertaken without conducting a death investigation, then it will be challenging to obtain comprehensive results. The one thing that will arise from this is the fact that the forensic will not achieve collecting primary evidence. In the case where they engage a death investigation, it will be easier to secure the place where no one will have terminated the evidence. The critical thing is to ensure that no one has tampered the information collected. In the case where the people have tampered it, then it will be challenging to determine who conducted the crime. It will also be difficult to recover anything that may have been lost in the process of committing the crime (Graham, 1997).  The other thing is that the police will have difficult times as they will have difficulty nights trying to connect the crime with no sufficient information. It is essential since it allows the investigation team to come up with comprehensive investigation and data of any crime. They will not have difficulties trying to back up their evidence while at court.
