Crime Scene Investigation

...Crime Scene Investigation John J. Camacho University of Maryland University College Imagine if solving crimes were done in an hour. In twenty four hours evidence is collected and processed and all suspects are investigated and dealt with as deemed necessary. There is a reason why things like this only happen on television, because this is very unrealistic. There are so many T.V. shows that glamorize this possibility; one of those shows is CSI: Crime Scene Investigation. This show is so popular that there are a few different versions; one set in Las Vegas, New York, and Miami. The show is based on crimes, usually murder, that is solved by the criminal investigation unit of the police department. Their jobs are to collect evidence from the crime scenes to help solve the crime. Because this is television all the crimes are solved within an hour and it does not go through the realistically long and tedious process of gathering and processing evidence. Season five episode twenty-one of CSI: Miami involves the murder of three people; a female personal trainer, a male who bought a car from a rich couple, and a lawyer.

Crime Scene Investigation

...The purpose of crime scene investigation is to help establish what happened (crime scene reconstruction) and to identify the responsible person. This is done by carefully documenting the conditions at a crime scene and recognizing all relevant physical evidence. The ability to recognize and properly collect physical evidence is oftentimes critical to both solving and prosecuting violent crimes. It is no exaggeration to say that in the majority of cases, the law enforcement officer who protects and searches a crime scene plays a critical role in determining whether physical evidence will be used in solving or prosecuting violent crimes. Documenting crime scene conditions can include immediately recording transient details such as lighting (on/off), drapes (open/closed), weather, or furniture moved by medical teams. Certain evidence such as shoeprints or gunshot residue is fragile and if not collected immediately can easily be destroyed or lost. The scope of the investigation also extends to considerations of arguments which might be generated in this case (suicide/self-defense) and documenting conditions which would support or refute these arguments. In addition, it is important to be able to recognize what should be present at a scene but is not (victim's vehicle/wallet) and objects which appear to be out of place (ski mask) and might have been left by the assailant. It is also important to determine the full extent of a crime scene. A crime scene is not merely the immediate area...

Generally speaking, a person arrested for breaking a criminal law appears before a judge within twenty- four hours. The judge will inform the person of the charges and bail or conditions of release. For some minor offenses, the judge may allow the person to enter a plea of guilty or not guilty at the initial appearance. After the initial appearance, the defendant is entitled to a preliminary hearing to determine if there is sufficient evidence to continue the case. Generally the defendant will waive that right, and the prosecutor will file trial information, which is a formal statement of the charge. Following the filing of a trial information or indictment, the defendant will appear for an arraignment. At the arraignment, the court may read the formal charges and the...

...it is in their possession.

 Initial Collection * Before any evidence is removed from the crime scene, there should be an evidence custodian designated as the person in charge of initiating and maintaining all evidence. This person needs to document the crime scene location, as well as his time of arrival. There should also be a crime scene log established, witness list and documentation of identification, arrival and departure times of all law enforcement crime scene personnel.

 Record Keeping * The investigator who handles the evidence initially should affix her name, badge number and assignment to the package containing the evidence. When the evidence leaves the officer's possession, a record should be made in her case notes identifying to whom the evidence was given, the date and time, and the reason it was turned over. A signed receipt should be obtained from the person accepting the evidence and another signed receipt should be obtained when the item is returned. When the item is returned, the officer should examine the item and determine if the item is in the same condition as when it was discovered

...An Event-Based Digital Forensic Investigation Framework∗ Brian D. Carrier carrier@cerias.purdue.edu Eugene H. Spafford spaf@cerias.purdue.edu Center for Education and Research in Information Assurance and Security - CERIAS Purdue University West Lafayette, IN 47907 USA Abstract In this paper, we present a framework for digital forensics that includes an investigation process model based on physical crime scene procedures. In this model, each digital device is considered a digital crime scene, which is included in the physical crime scene where it is located. The investigation includes the preservation of the system, the search for digital evidence, and the reconstruction of digital events. The focus of the investigation is on the reconstruction of events using evidence so that hypotheses can be developed and tested. This paper also includes definitions and descriptions of the basic and core concepts that the framework uses. 1 Introduction Since the first Digital Forensic Research Workshop (DFRWS) in 2001 [Pal01], the need for a standard framework has been understood, yet there has been little progress on one that is generally accepted. A framework for digital forensics needs to be flexible enough so that it can support future technologies and different types of incidents. Therefore, it needs to be simple and abstract. On the other hand, if it is too simple and abstract then it is difficult to create tool requirements and test procedures for each phase. For this paper...
