Criminal Investigations History of criminal investigations The first "detective force" dates back to 1750, when a small group of community members called the "Take Thieves" banded together and rushed to crime scenes to investigate (Swanson, 2003). This group, spearheaded by Henry Fielding, eventually led to the founding of a police force in London (Swanson, 2003). The next famous "father of criminal investigation" is Robert Peel, who authored the twelve "Peel's Principles," outlining

Potential contamination issues with the collection of evidence include: environmental and human factors. Environmental contamination occurs when heat, humidity and related elements will damage any kind of clues that are at the scene of the crime. While human factors, are when investigators, emergency personnel and the family could touch something (effectively contaminating the crime scene). Once this happens, is the point that it is more difficult for investigators to establish

All samples must be properly collected, using gloves and other tools in order to prevent contamination, as well as properly stored until analysis can be performed. It is vitally important that this chain of evidence be maintained so that the evidence collected from using the samples can then be admissible in a court of law. This requires those collecting and storing samples not only to use gloves and tools to

Abstract This paper provides an overview of the use of DNA in criminal investigations. It shows how DNA can be helpful and harmful in terms of validating a narrative, how it has been used to exonerate inmates and used to wrongfully convict others. It shows how juries view it as 95% accurate while Israeli scientists show that DNA evidence can be manufactured simply by scientists obtaining access to a DNA profile.

Capital Punishment & DNA DNA Evidence, Capital Punishment, & the Criminal Justice System Capital Punishment is an issue of great contention. There are many people who strongly favor the use of capital punishment; there are also a great number of people that are adamantly against the use of capital punishment. DNA (deoxyribonucleic acid) evidence has become a crucial factor in the criminal justice system and the issue of capital punishment. Since the

Criminal investigation plays a crucial role in law enforcement in relation to the arrest, prosecution, and conviction of criminals. This paper examines the evolution of criminal investigation research in light of the developments that have taken place in this field. A history of the criminal investigation is also discussed as well as a definition of the criminal investigation process. The author also examines how DNA, fingerprinting, and forensic science have
