Criminal investigation

Arrived at 6:28. Today our PT was individual runs. The weather was cool, but not cold, and was thus perfect for running outdoors. I tried to keep up with Duck and Steele, and managed to do so for the first half fo the run. My goal is always to make it to the halfway point without having to slow down to a walk. I achieved this goal, but was feeling short of breath. I shortened my walking stints as short as possible, and only did so twice. As usual, I finished strong with a sprint to the finish.…

DNA is the process of using and collecting DNA from crime scenes to solve criminal investigations and to ensure accuracy and fairness in the Criminal Justice System. DNA profiling has grown significantly in the past years and has been extremely useful in identifying suspects, criminals and other people involved in the crime. If the suspect is unidentifiable, DNA evidence is compared to a DNA database to identify the criminal. DNA testing has both advantages and disadvantages many of which relate…

conclusions (NSRL Rochester, 2015). In the criminal justice field it would generally commence as an inductive process and cases are used to illustrate the application of the scientific method to criminal investigation (Osterburg, 1981). The scientific method can be applied to criminal justice research, and can formulate or construct an accurate representation of the world (Osterburg, 1981). The scientific method is commonly used in criminology and criminal justice. It is applied to gather…

DNA testing which can also be label as DNA fingerprinting, DNA profiling and even DNA typing is considered a forensic technique that can be used to identify a person by their characteristics of their DNA. (What is DNA Testing?, 2016). DNA testing was developed in 1985, to identify a suspect and placed that initial suspect at the incident location during the time of the crime. DNA testing have evolve in the past decade that is can be used to study the animal populations. DNA testing can collected…

Some federal circuits require that the police have positive information that defeats the ambiguity and thus are allowed to proceed with the search. In U.S. v. Matlock, a resident of house consented to search of Defendant’s bedroom. She claimed that they shared the bedroom. She consented voluntarily to the search of the house, including the east bedroom on the second floor which she said was jointly occupied by Matlock and herself.

Introduction: Offender profiling can be defined as making predictions about offender’s characteristics from the way they behaved during a crime (Davies & Beech, 2012). Offender profiling can play an important part in criminal investigations, especially when there is no DNA left at crime scenes. It requires using other types of evidence such as characteristics of the crime scene and eye-witness testimonies from victims and witnesses. Profiling techniques can be unified with police forces to help…

Codes of ethics are usually adapted by dissimilar organizations in order to help its members by giving them the understanding of things, which are right and wrong.

In law enforcement, there are codes that…

analysis and its use in the judicial system however, is quite complex. From its infancy until now, DNA use in forensics has grown into something that has become quite beneficial to the court system. Many a jury, lawyer, judge, and person involved in criminal proceedings has been affected by the use of DNA evidence. The usage of DNA in forensics has affected the court system by supplying stronger evidence for juries to come to verdict with, helping to free wrongly convicted persons, and solving…

The guidelines for the preliminary investigation of a criminal case are as follows: Officers authorized to conduct preliminary investigations are city prosecutors, judges of the municipal trial courts and municipal circuit trial courts, national and regional state prosecutors, and other officers as authorized by the law. The preliminary investigation begins when a…

Reliability and Validity Reliability refers to the extent to which a series of similar assessments are consistent in the result they give (Rubin & Babbie, 2010). This is a crucial aspect of carrying out tests which may be a way of testing bias as well as distortion. For instance, this can be tested in an actual situation with a DNA test. A DNA test that needs to show if a suspects DNA matches a sample at a crime scene. To ensure that the scale is reliable, the sample can be tested twice and if…
