(i) This law establishes the principles of creation and maintaining a database of DNA profiles, for identification purposes, and regulates the collection, treatment and samples of preserved human cells, their analysis and obtaining DNA profiles, the comparing profiles method of DNA extracted from samples and the processing and storage of the respective information in computer.
(ii) A database of DNA profiles also serves purposes of criminal investigation.
(iii) It is forbidden to use the analysis and treatment of any type of information obtained from analysing samples for different purposes of under section 4.
The reason and purpose of this law include the Civil and Criminal identification case together because this law wants to reduce pressure

“In most cases, the process involves the generation of a DNA profile from a crime scene sample (which may include biological material taken from the body of a victim, as in sexual assault cases) and comparing this with a sample taken from a suspect (which may be given voluntarily or pursuant to an order issued by a court).”
France, the legal authority can collect the DNA sample from 1) a suspect 2) a convicted offender that has a serious offence following from list of law and an imprisonment that an offence is not less than 10 years.
Germany, regarding the criminal procedure code section 81g (1) stated there is the criminal cases that the legal authority has to collect the DNA sample; 1) a serious offence 2) minor offence 3) a sexual offence. The legal authority can collect the DNA sample from 1) a suspect 2) a convicted offenders 3) third party (witnesses) 4) minors (14-17 years) 5) a mentally ill person. Obviously, the German law has clearly obtained the DNA sample especially from the third party

The process of the forensic evidence can help track down the girl. Since then, the forensic evidence became a police investigation’s tool that has been a surge of media attention and has a strong reputation. The forensic evidence helped the legal authorities to find causes for the disappearance of the girl. The duty of the police has been discussed regarding the reliability of forensic evidence which greatly assisted in the police investigation of this case.
On 7 September 2007, the police officers charged the girl's parents, as suspect. However, on 21 July 2008, the police officers would have to release the child parents because there was no evidence. Even nowadays there are no clues about the missing McCann at all. McCann parents will give an award to the person who can find their missing girl.
However, the PJ issues are also being attacked by British media. The British media have many questions about the police work. The crime scene was not secured and is preserved by the PJ. There were police errors about technical investigation and there was a failure to recover traces from the crime scene. There is the lack of detailed data collection from maritime police or border police after the McCann
The analysis of the samples should be used only to confirm or negate match between the sample taken from the crime scene fgand the sample taken from the suspect. That is, it should sdfremain as an identifgication tool only. There should be no further analysis of the DNA to suggest psychological characteristics that would make the suspect more likely to have cdfommitted the crime. This rule should apply also to samples taken from convicted dfdoffenders for a data vor dagta bank.
The repeat segments are cut out of the DNA strand by a restrictive enzyme that acts like scissors and the resulting fragments are sorted out by electrophoresis (Saferstein 391). However, there are some drawbacks using the RFLP method in the forensic science community. The RFLP technique requires a large amount of DNA and must be of high quality and cannot be degraded (Jones). Forensic scientists and the law enforcement community determined a need for a DNA profiling method that could be used on smaller DNA samples. Thus, the RFLP technique has been almost entirely replaced by Polymerase chain reaction.
Nowadays, DNA is a crucial component of a crime scene investigation, used to both to identify perpetrators from crime scenes and to determine a suspect’s guilt or innocence (Butler, 2005). The method of constructing a distinctive “fingerprint” from an individual’s DNA was first described by Alec Jeffreys in 1985. He discovered regions of repetitions of nucleotides inherent in DNA strands that differed from person to person (now known as variable number of tandem repeats, or VNTRs), and developed a technique to adjust the length variation into a definitive identity marker (Butler, 2005). Since then, DNA fingerprinting has been refined to be an indispensible source of evidence, expanded into multiple methods befitting different types of DNA samples. One of the more controversial practices of DNA forensics is familial DNA searching, which takes partial, rather than exact, matches between crime scene DNA and DNA stored in a public database as possible leads for further examination and information about the suspect. Using familial DNA searching for investigative purposes is a reliable and advantageous method to convict criminals.
The Trace Evidence Unit is known to examine the largest variety of evidence types and uses the biggest range of analytical methods of any unit. materials are compared with standards or known 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 investigators use it to solve cases and convict criminals. Trace evidence was first discovered by Edmond Locard. Edmond Locard was born in 1877, and founded the Lyon’s Institute of Criminalistics.

In the world of forensic science, exoneration holds a very crucial role. In cases where a person has been convicted of a crime and needs to be proven innocent, exoneration plays a key part. It is what helps the court to decide in a just manner whether the crime was committed by that person or not. Exoneration is based on DNA evidence and therefore, is the most authentic. The main purpose of exoneration is to help the legal system by allowing innocent people to be discharged of guilty verdicts. Majority of the legal systems are built on such structures that the people responsible for crimes can be identified and penalized. Exoneration removes the burden, charge or responsibility which is being erroneously imposed on someone by the law. On one hand where it finds out about the actual convict, it also helps the innocent.
DNA in forensic science has been around for a long time. DNA has had help in solving almost every crime committed. There have been a lot of crimes where people are raped or murdered and the person who did it runs free. Scientists can collect the littlest item they see at the scene, such as a cigarette butt or coffee cup and check it for DNA. People have spent years in jail for a crime they didn’t commit till DNA testing came into effect. People are getting out of jail after 20 years for a crime they didn’t commit, cause of the DNA testing. DNA has helped medical researchers develop vaccines for disease causing microbe. DNA has become a standard tool of forensics in many murders and rapes.
Overall, though, I believe that Stein is the closest scholar here-mentioned to have accounted for the explanation behind these controversies. The main mistake made by many modern scholars lies in the planning and the research – too much effort is spent on seeking to explain this opposition between the Proculians and the Sabinians in terms of two internally coherent law schools which differ entirely and have held controversies stemming from a specific occurrence. I have personally, as a student of the Roman law, found it difficult in reading the sources and differing theories from scholars to do just this – because, as Scarano Ussani stated, nowhere, in the mass of research that has been done, have any definitive results been reached. As afore-mentioned, I ruled out the political explanation for the purpose of answering this question, and the social explanation does not add a great deal to the debate for me. The theories supporting the social standpoint as addressed in this essay are among the worst for choosing to ignore many of the hard facts in order to make their theory fit better. This leaves only the philosophical and methodological explanations. The philosophical explanation is a reasonably sound one, although as explored above, I do believe that its significance has been largely exaggerated. There is no doubt over the fact that philosophy has played an influential role - even if you only look at Gaius’ ius gentium which contains a certain level of Stoic influence, but as mentioned above there are major differences which have been overlooked slightly in those arguments. The methodological explanation is another seemingly logical one, and the most reliable of all theorems explored in this essay, in my opinion, as it i...
The criminal justice system has changed a lot since the good old days of the Wild West when pretty much anything was legal. Criminals were dealt with in any fashion the law enforcement saw fit. The science of catching criminals has evolved since these days. We are better at catching criminals than ever and we owe this advancement to forensic science. The development of forensic science has given us the important techniques of fingerprinting and DNA analysis. We can use these techniques to catch criminals, prove people's innocence, and keep track of inmates after they have been paroled. There are many different ways of solving crimes using forensic evidence. One of these ways is using blood spatter analysis; this is where the distribution and pattern of bloodstains is studied to find the nature of the event that caused the blood spatter. Many things go into the determination of the cause including: the effects of various types of physical forces on blood, the interaction between blood and the surfaces on which it falls, the location of the person shedding the blood, the location and actions of the assailant, and the movement of them both during the incident. Another common type of forensic evidence is trace evidence. This is commonly recovered from any number of items at a crime scene. These items can include carpet fibers, clothing fibers, or hair found in or around the crime scene. Hairs recovered from crime scenes can be used as an important source of DNA. Examination of material recovered from a victim's or suspect's clothing can allow association to be made between the victim and other people, places, or things involved in the investigation. DNA analysis is the most important part of forensic science. DNA evidence can come in many forms at the crime scene. Some of these forms include hair; bodily fluids recovered at the crime scene or on the victim's body, skin under the victim's fingernails, blood, and many others. This DNA can be the basis of someone's guilt or innocence; it has decided many cases in the twentieth century. As the times continue to change and the criminals get smarter we will always need to find new ways to catch them. Forensic science is the most advanced method yet, but is only the beginning. As the field of science grows so will the abilities of the
Once a crime has been committed the most important item to recover is any type of evidence left at the scene. If the suspect left any Deoxyribonucleic acid (DNA) at the crime scene, he could then be linked to the crime and eventually charged. A suspect’s DNA can be recovered if the suspect leaves a sample of his or her DNA at the crime scene. However, this method was not always used to track down a suspect. Not too long ago, detectives used to use bite marks, blood stain detection, blood grouping as the primary tool to identify a suspect. DNA can be left or collected from the hair, saliva, blood, mucus, semen, urine, fecal matter, and even the bones. DNA analysis has been the most recent technique employed by the forensic science community to identify a suspect or victim since the use of fingerprinting. Moreover, since the introduction of this new technique it has been a la...
In today’s time, modern Crime Scene Investigation has increased rapidly. From throughout the late 1900’s and in the early 2000’s (Taylor 1). For all of the evidence that they find, a solid foundation has formed over the thousands of years of Crime Scene
People disappear for several reasons; it could be to start a new life, it could be to hide from someone or it could be because someone doesn’t want you found. This paper is about the disappearance of Yessenia Suarez and her two children. Can the police determine if a crime was committed and by whom? This paper will describe the evidence and the timeline of events in the case.

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.
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
