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
