Question 1

When analyzing the blood droplet or bloodstain, the presence of scallops, spatter, tails or spine usually assist the analyst to identify the path that the droplet was travelling in at impact. Unless the impact of the droplet was at 90o, the axis that is associated with the travel direction of the droplet tends to be longer due to droplets skimming action on the target. For example, at an impact of 90o, smaller scallops tend to appear around the stain’s entire periphery. When the impact is 70o, larger scallops tend to be more concentrated on one side of this Continue reading...

ABSTRACT

Bacteria can be beneficial to other organisms or can be pathogenic. Their diversity and versatility have caused scientists to study them deeply. A classification procedure using morphological and biochemical tests have since been implemented in microbiological studies in order to characterize isolated microbes. In this experiment, two unknown bacteria were characterized using Gram staining and a number of metabolic assays. Using the tests results, the unknown bacteria were successfully classified as Pseudomonas aeruginosa (Unknown A) and Staphylococcus aureus. Both bacteria are commonly found within humans and are occasionally potentially dangerous especially for people with compromised immune system. Additional testing Continue reading...

To determine whether the method used by an expert is valid, several factors are considered. The first factor is to determine whether the technique being employed or the theory used can be or has been subjected to testing. The second factor is whether the methodology has been done through peer review leading to its publication. The third factor requires the Continue reading...

In almost all homicide cases, the blood is considered to be the most common physical evidence that the investigators will find in the crime scene. The blood is considered to be the most vital physical evidence that can be taken for forensic analysis to help solve crimes and in reconstructing the crime scene. Geberth (2007) emphasizes the crucial role of bloodstain analysis in aiding the investigators when trying to understand what happened between the victim and assailant, such as creating the sequence of events. The patterns of bloodstain as evidence on a crime scene can illustrate the victim’s Continue reading...
