What Are the Methods of Inquiry and How Are They Used in Criminal Investigation?

The popular television show, CSI: Crime Scene Investigations has been on the air for 12 years, and it has brought forth the behind-the-scenes actions of criminal investigations, even if its portrayals are not always scientifically accurate. This has caused an interest in the forensic sciences that has led most people to a skewed view of how a criminal investigation actually works. The reality of a criminal investigation is that it is generally more tedious and difficult than the theory of criminal investigation would have you believe. By examining the forensic and investigative procedures of the case of Pamela Foddrill, it is apparent that the theory of criminal investigation was not representative of the procedures concerning examination

Physical evidence is anything that can establish a crime has occurred and anything that links the crime to a criminal. Three examples of physical evidence are fibers, weapons, and hair.

One of the most important purposes of physical evidence is to establish the identity of a suspect or victim. Some of the most valuable clues at a crime scene are fingerprints. "Processing a crime scene" is a long, tedious process that involves focused documentation of the conditions at the scene and the collection of any physical evidence that could possibly shed light on what happened and point to who did it.

However, back in the 1980s, detailed studies were done to try to accomplish this task. One specific comprehensive study was done in 1984 by Peterson et al. In this study, the analysts found that physical evidence was discovered in only about twenty to thirty percent of serious crimes (Peterson, 2013). When each of the crimes were studied separately, however, they found that only crimes such as homicide, drug, or rape resulted in a large chance of physical evidence being found at the crime (Peterson, 2013). Cases such as attempted murder, burglaries, and robberies yielded lower chances of the retrieval of physical evidence from the crime (Peterson, 2013). When considering all of these possible crimes, the most commonly collected evidence were controlled substances, and then in lesser amounts, there was other physical evidence such as blood, hair, firearms, and fingerprints (Peterson, 2013).

Forensic evidence plays a huge role in most criminal cases. After the Daubert trial, forensic scientific evidence was reevaluated in criminal and civil cases. Scientific and forensic types of evidence can be extremely helpful in proving the case. It can help identify the suspect in a criminal case. That will help put a criminal in prison. There are many different types of forensic evidence that can be considered as scientific evidence. The different types include DNA matching, fingerprint identification, and hair evidence. The methods used to show these types of evidence are usually beyond the scope of knowledge that judges and juries know. Those types of forensic evidence are usually introduced as scientific evidence. Scientific evidence can sometimes be omitted from a courtroom or

In a criminal investigation, there is the need to break down two things. Firstly, the investigation itself and secondly the investigator involved. It is of utmost importance that the criminal investigation is done accurately, failure to do so will have negative consequences on the society. Investigation involves the collection of facts, scenarios and situations which are directly or indirectly related with the case. Whereas investigator is the person who should observe, question, analyze and scrutinize the available details. Careful evaluation then helps to achieve the much needed evidence. Criminal investigation is one of the most essential functions of the Law Enforcement agencies, as it is their prime responsibility to maintain a secure environment and

The Criminal Justice process involves the gathering of evidence by the proper authorities, witness testimonies, expert testimonies, psychological examinations, forensics reports,

What three aspects does a forensic autopsy seek information about? Describe each of these aspects.

The procedures and techniques used in any criminal investigation help the investigators to do their investigation properly. By correctly following the investigative stage, the investigators can improve the quality of their case and investigation and the police will get a better chance to solve any criminal case. In any criminal investigation, five stages are involved. The police and investigators have the duty to follow all this stages, in order to get the best results.

Followed by documenting all investigation performed, obtained evidence along with the witnesses and suspects interviews. Always the report should be accurate and with no mistakes, also make sure that everything went thru the proper channels complying with the law, before submitting it to the prosecuting attorney. Finally prepare & testify in court.

They have to make sure that before they entered the crime scene, nothing in the scene should have been moved. While they are going through a walk-through, they may have to construct theories about what happened in the crime scene based on visual examination. Investigators have to take photographs of the scene and will later on be collected. Taking photographs of the scene will help them solve the crime because there are some points of the investigation that investigators may have overlooked evidence, and that evidence could be found in the photographs. After taking photographs of the scene, they will start to collect clue and evidence that may lead them to their possible suspect(s). What they may find in the crime scene are fingerprints which can be done using colored powder and a brush, other thizngs such as blood, firearms, hair, glass and many more things that can be found in the crime scenes.

3. After interviewing the victim of a crime and two witnesses, and examining the crime scene and the physical evidence, you use all of this information as a basis for developing a unifying and

The first is the preservation of the crime scene. If the crime scene has not been secured and borders not set up this will result in the contamination or loss of physical evidence, which is crucial in a reconstruction. The second is an investigator is the use of inductive and deductive reasoning, not have any preconceived ideas) by using the facts of the case, in addition to photography, video, crime scene sketches, and other documentation to draw inference (M.U.S.E. (2), 2017)

Nothing is more crucial to any investigation than the actions of the first officers on the scene and the actions they take regarding the preservation of the crime scene, detention of witnesses and an arrest if possible. The immediate objective of the first officers on the scene must be the safety of all parties involved and all else follows

Evidence is defined as any matter of fact, the effect, tendency, or design of which is to produce in the mind a persuasion, affirmative or disaffirmative, of the existence of some other matter of fact that a crime has been committed.(Paul B. Watson, 1986) In a legal sense, evidence is the information presented in court during a trial which enables the judge and jury to decide a particular case (Garland & Stuckey, 2000). There are two main types of evidence, which are testimony and physical items which can be presented to the judge and jury during a criminal trial. Physical evidence is any evidence found at the perpetrator’s
