A DNA profile is generated with the help of the DNA is that is left behind by the skin cells. This is known as the Touch DNA. Even though the samples that are used in this case are very small but the Touch DNA can be retrieved with the help of a technique that is launched recently and is known as the Polymerase Chain Reaction (PCR) which will take small samples of the DNA and make similar millions of copies within just two to three days . As the collection of fingerprints is a difficult task, and there is a ...

An analysis of how the criminalist in Ted’s case handled the evidence and whether it was positively or negatively involved in the outcome of the case Voelker & RDH (2012) proclaims that the investigators obliged that Bundy to offer a dental impression to aid in the investigation but Bundy refused. After sometimes, the criminalists were granted a search warrant to get the impression in any possible tactic.

The type of bloodstain evidence at the scene is a cast off pattern. According to Becker (2005), a cast-off pattern normally results in blood striking nearby surfaces such as walls, floors and ceilings. A cast-off pattern indicates that a blunt force trauma to the head. The large wound on top of the head is indicative of repeated use of the blunt force weapon on the victim. The first step in the documentation process of the room would involve conducting an initial scan of the room to ascertain the evidence present. This would then be followed by photographing of the scene in ...

Mass disasters are events that occur without warning and causes large number of deaths. These disasters may be natural, accidental or intentional. Natural disasters include calamities like earthquakes, tsunamis, flooding etc., while accidental disasters include building collapses, train and aircraft disasters. Intentional disasters are observed recently with acts of terror like bombing and other weapons of mass destruction. The large number of human lives lost in these disasters requires identification. The forensic examination is not only for humanitarian reasons but also for possible criminal investigations. DNA analysis is one of the best methods for identification of individuals from ...

Mathematics

The topic for this research study is the applicability of DNA evidence in resolving criminal cases. Thesis Statement: DNA evidence is not an accurate means of identification of suspects because DNA analysis can be compromised, prone to errors and opposing interpretations due to external factors such as environment, contamination and bad laboratory practice. According Gardner and Anderson (2009), DNA evidence remains to be the most accurate means to identify a person. It has been an important development in criminal investigation and also a significant contribution to the entire criminal justice system. It provides a reliable basis for conviction. It has ...

Since its introduction in the United States in 1987, the use of forensic techniques analyzing deoxyribonucleic acid (DNA) has evolved into a standard form of evidence in criminal proceedings (Calandro, Reeder, & Cormier). There are at least three major ways that DNA forensics can be utilized in combating crimes. First, it can act as evidence of the presence of a suspect at the scene of a crime, or for certain crimes that can leave DNA evidence such as rape, even stronger evidence in support of guilt. Second, DNA forensics can be utilized to help solve older crimes that have gone cold, where materials ...
