My team members and I received information that a man called Bob Butcher, the chairman of the ‘England for the English’ movement was planning to cause disruption at the official opening of a new Mosque in Ealing on the 19th of April 2014. Bob is a well-known man to the police, he has a number of convictions for serious assault. Ted Towser who was recently Bob Butcher’s number two approached me and told me that Bob was up to something ‘serious’ and wants nothing to do with it and he was willing to give further information about Bob’s plans. On the 14th of April I was told that Ted was found lying in the street at 3am that morning and was unconscious in hospital, having been seriously assaulted, he had what looked like handcuff burns on his wrist, deep lacerations on his back that looked like knife injuries and he had been shot in both knees. Bob had disappeared and was believed to be trying to leave the country using a network of links sympathetic to his movement. On the 14th of April 2014 at 14:06pm I and my team members carried out a crime scene investigation in Bob’s garage which required us to recover evidential items of potential forensic importance from a crime scene and submit them to the laboratory for further analysis. These Forensic analyses of the items of physical evidence may have provided answers to a number of important questions. The effective recovery of the items of physical evidence is crucial to the success of the subsequent inquiry. The following items were recovered during the investigation: Date/Time Seized Bag No Exhibit No Description 14/4/14 1420 TWS0102 EA/1 One (1)Black trousers 14/4/14 1423 S00640994 EA/2 Two (2) Shell casings 14/4/14 1428 S00640995 EA/3 One (1) ALDEASA Receipt 14... ... middle of paper ... ...ll I think I and my team did okay as we did recover some crucial evidence and tried to work well as a team however as explained above there are no room for errors when it comes to providing evidence at court.

Ballistics is the scientific study of the dynamics of projectile and bullet trajectory. Crime members utilize equipment that will allow to match individual characteristics to a known object in order to make a comparison. Just like the Locards exchange principle “when two objects come in contact, evidence is always left behind”. When a weapon has been shot, the barrel of the gun will leave marks on the bullet. With the marks left behind, one can scientifically prove the kind of weapon used, trajectory and estimate the distance between criminal and victim.

Crime scenes are known to have many clues left behind. The obvious would be a the body or bodies, clothing, and sometimes even the murder weapon. While these are great way to solve a case there's another kind of evidence; trace evidence. Trace evidence are small pieces of evidence that are laying around a crime scene. There are many types of trace evidence some of them include metal filings, plastic fragments, gunshot residue, glass fragments, feathers, food stains, building materials, lubricants, fingernail scrapings, pollens and spores, cosmetics, chemicals, paper fibers and sawdust, human and animal hairs, plant and vegetable fibers, blood and other body fluids, asphalt or tar, vegetable fats and oils, dusts and other airborne particles, insulation, textile fibers, soot, soils and mineral grains, and explosive residues. Although these are the most common found elements, they are not the only ones. The Trace Evidence Unit is known to examine the largest variety of evidence types and used the biggest range of analytical methods of any unit. materials are compared with standards or knowns samples to determine whether or not they share any common characteristics. In this paper I will discuss the different kinds of trace evidence and how crime scene investigaros use it to solve cases and convict criminal.

The amount of evidence can either help win or lose a case. Every crime scene has evidence available for officers to collect. It is important for them to know what the standard protocol is for collecting evidence and how to properly collect it without contamination.

Forensic Science, recognized as Forensics, is the solicitation of science to law to understand evidences for crime investigation. Forensic scientists are investigators that collect evidences at the crime scene and analyse it uses technology to reveal scientific evidence in a range of fields. Physical evidence are included things that can be seen, whether with the naked eye or through the use of magnification or other analytical tools. Some of this evidence is categorized as impression evidence2.In this report I’ll determine the areas of forensic science that are relevant to particular investigation and setting out in what method the forensic science procedures I have recognized that would be useful for the particular crime scene.
Many of us enjoy watching crime scene investigation shows, but in the criminal justice system forensic investigation is an essential field that requires upright observations and a prodigious interpretation. Under forensics, it is difficult to blame someone without scientific data. For that reason, Larry K. Gaines author of the textbook Criminal Justice in Action explains the importance of Blood Spatter Analysis. Specialist can learn a great deal about violent crime by examining where blood landed at the scene, the size and consistency of drops, and the pattern of blood spatter (Gaines, 2011). Consequently, an article of the Blood Spatter Analysis will be used to explain the research methodology the author uses to proceed certain investigations.
As far back as 1832, James Marsh was the first to use forensics at trial to give evidence as a chemist in 1832. Since that time forensic science and evidence has come a long way in various ways and technology to help in determine if the suspect is guilt or not, through such things as DNA testing, blood, and fingerprints. The first forensic police crime lab was created in 1910. The contributions of Dr. Edmond Locard, a French scientist and criminologist, proposed that “everything leaves a trace”. This principle is still valid today as it was so many years ago. No matter how small, the specialized trained technicians and investigators can take these methods and go to a crime scene to get evidence. “Forensic science is the application of sciences such as physics, chemistry, biology, computer science and engineering to matters of law.” (Office of Justice, 2017) These different sciences can help achieve and assist in solving a case. Forensic science has also the ability to prove that a crime was committed, it can find the elements of the crime, it can help place the suspect at the scene and whether the suspect had any contact with the victim. However, in the last several years the techniques and with the use of technology the evidence that forensic science uncovers can also exonerate an innocent individual who has been falsely accused of the
Physical evidence is additionally important in every criminal investigation because too often witness accounts are sometimes biased or unreliable. Physical evidence such as trace evidence, DNA, and fingerprints may objectively attach one or more persons to a victim or suspect to a crime. Favorably, physical evidence can also demonstrate inestimable for exonerating an innocent suspect. Laboratory members and criminal investigators should perform together to resolve the biggest portion of evidence to institute the right suspect for a strong prosecution. Willingly, investigation officers should aggressively contact laboratory personnel when questions arise about the cases because DNA evidence is sensitive.
