List of Illustrations
Figure 6.1. This diagram depicts how the sphere is formed in f‌light due to
surface tension. The arrows show the direction of air pressure as
the droplet falls. 115
Figure 6.2. This diagram depicts how a bloodstain pattern may indicate
the direction the blood source was moving at the time of
deposition. 116
Figure 6.3. The circular bloodstain () and the elliptical bloodstain () do
not provi de information about the direction the blood source was
moving at the moment of impact. 116
Figure 6.4. Bloodstains deposited on a concrete surface. 117
Figure 6.5. Bloodstains deposited on a carpeted surface. 117
Figure 6.6. Bloodstains deposited on clothing. 118
Figure 6.7. This f‌igure depicts the angle of impact calculation. As the
trigonometric table indicates, the sine of 0.5 is 30, indicating a 30
degree angle of impact. 119
Figure 6.8. This f‌igure depicts the inverse relationship between the length
of the droplet and the angle to the blood source; the longer the
droplet, the closer it was to the blood source. 119
Figure 6.9. This f‌igure depicts a two-dimensional analysis of an impact
pattern to determine the area of convergence. By drawing lines
through the centre of several bloodstains, a view of the area of
convergence of these bloodstains can be seen. 121
Figure 6.10. This f‌igure depicts a three-dimensional analysis of an impact
pattern. By applying trigonometric functions to each bloodstain,
an area of origin can be visualized. 121
Figure 6.11. This f‌igure depicts the inverse relationship between the amount
of force and the size of the resulting bloodstain: the lower the
force, the larger the bloodstain. 122
