At the conclusion of each laboratory project, a written report will be required. This is your opportunity to tell the instructor what you have learned from the weekly content by focusing on the criteria listed above. Reports should display critical thinking as well as demonstrating a grasp of how the information in this week’s class builds on previous class materials.
Prior to completing this assignment, review your Week Six Final Paper to determine what aspects of this week’s material may be used. You should also review the week’s readings, lab materials, and lab notes. Your report must focus on the collection and analysis of blood evidence from a crime scene, and it must include the following:
Describe the results you obtained from each laboratory activity.
Describe the history of blood evidence.
Explain the characteristics of blood.
Describe common tests for blood and explain how blood is analyzed.
Explain how blood stains and spatter are collected and analyzed.
Articulate what aspects of this week’s material you can use to complete your analysis of the crime scene in your Final Paper.
Having answered the questions, there was a requirement to carry out a single blood drop analysis from different distances. To accomplish this, one had to document the blood stain diameter of a single drop at varying distances and then proceed to analyze the blood diameter of varying drips at the same distance. The first bloodstain considered was at a distance of 15 centimeters. The diameter of this stain was 7 millimeters in diameter. It was observed that the bloodstain size was small and circular. At 30 centimeters, the bloodstain had a diameter of 12 millimeters.
It was noted that the size of the stain increased and appeared as small spines. At 45cm, the bloodstain measured 20mm. it was observed that the size of the stain got bigger as the number of spines increased. At 60cm, the stain had a diameter of 25mm. The chief observation was that the size of the stain enlarged as the degree of spines increased. Satellite spatter also appeared at this distance. There was a distance of 75cm. It was revealed that the diameter of the stain stood at 28mm and that the size got bigger with an increasing number of spines. Besides satellite spatters and...
