Past events cannot be observed, cannot be predicted or deduced from physical evidence, and cannot be tested experimentally. The forensic scientific method is a modified form of the scientific method that compares anamnestic evidence obtained by investigators with observable physical findings discovered at the crime scene, in the crime laboratory, or in the autopsy suite.
Forensic science follows the steps of the scientific method, from the observation of the crime science, collection of initial data, experimentation and validation of results that are generated from the analyses.
Molecular biology as well as other analytical techniques have been developed and improved the field of forensic science, resulting in precise details and additional information that could be used in court.
Introduction The field of forensic science involves the application of the scientific method to questions regarding criminal cases Brettell et al.
Similar to an experiment conducted by a scientist, a forensic science case allows a forensic scientist to use the four major steps of the scientific method in order to solve a criminal investigation. To date, the results generated from forensic analysis are accepted as evidence in court hearings.
The power of forensic science was recognized as molecular techniques which were initially designed for biomedical purposes were applied to the judiciary system. Methods in isolation, as well as manipulation, of deoxyribonucleic acid DNA from different types of tissues have facilitated the precise identification and comparison of biological materials between suspects and victims of a crime.
In addition, other assays involving other biological materials such as pollen and insects, have increased the specificity and reliability of the field of forensic science.
The analysis of insects, also known as entomology, has allowed a forensic scientist to determine stages of decomposition of human bodies, as well as determine whether a certain material of interest has been exposed or transported from one place to another.
On the other hand, the study of pollen or palynology, has facilitated forensic analysts in investigating conditions of the crime scene based on the presence and classification of pollen on the surfaces of materials of interest that were collected at the crime scene.
The employment of forensic data has thus revolutionized the field of criminal justice because it has provided an additional means of determining whether an individual should be convicted of a crime Hunter, In addition, forensic science has also helped in reviewing cold cases, or unresolved crime cases that are decades old, and has given light on the actual details of the crime.
Observation and description of a phenomenon or a group of phenomena Forensic science, similar to any scientific investigation, involves the observation and description of a phenomenon or a group of phenomena.
The usual phenomenon involved in a forensic case is a crime, wherein an unlawful act was performed in a specific area. The location of the crime is known as the crime scene and it is important for a forensic scientist to look at the entire scenario in order to generate an initial assessment of the case.
The observation involved in this process includes the collection of photographs of the entire crime scene, as well as gathering smaller yet essential specimens such as blood stains, hair strands, fibers, pollen, finger- and footprints. Formulation of a hypothesis or hypotheses to explain the phenomena Based on the initially collected information, the forensic scientist may generate a number of possible scenarios that could have taken place in the crime scene.
The possible scenarios formulated by a forensic scientist are equivalent to the hypotheses of a scientific experiment. For example, the presence of blood in the crime scene easily signifies that there was some kind of physical injury that occurred at the crime scene.
However, it should be understood that with this kind of inquiry, there are several hypotheses that are presented. One hypothesis is that some kind of physical assault was committed by an unidentified individual.
Another hypothesis could pinpoint a person of interest as a possible culprit of the crime. A few other individuals can also be suspected to be involved in the crime. However, it should be understood that unless a human body is found, it is difficult to determine whether a murder was indeed committed.
In addition to the question of who committed a certain crime, a forensic scientist also designs additional hypotheses which attempt to answer the question of how the crime was actually committed. Formulation of hypotheses also includes the sequence of events of the entire crime, such as what the criminal first performed and when exactly was a certain murder committed.
Use of the hypothesis to predict the existence of other phenomena, or to predict quantitatively the results of new observations In order to answer the hypotheses that were formulated by a forensic scientist, all specimens collected in the site are brought into the forensic laboratory for further analysis Lee and Ladd, This step is thus equivalent to the experimental step of the scientific method.Running head: SCIENTIFIC METHOD APPLIED 1 Scientific Method Applied to Forensic Science Kathy Wingfield CJA/ February 6, Stacy Hernandez SCIENTIFIC METHOD APPLIED 2 Scientific Method Applied to Forensic Science Scientific method is the way to investigate why or how something works.

The forensic examiner must observe an incident or situation. How this scientific method step relates to forensic science would be, for example, in a crime scene investigation involving ballistics.
The forensic scientific method is a modified form of the scientific method that compares anamnestic evidence obtained by investigators with observable physical findings discovered at the crime scene, in the crime laboratory, or in the autopsy suite.
It makes it natural for this science to use not only specific forensic methods, but general scientific method tested by time and different branches of natural and physical knowledge as well.
