Impact spatter pattern
A bloodstain can present itself differently depending on the situation and the material on which it appears, and bloodstains may be hard to examine on porous surfaces such as fabric, and may be distorted. Bloodstain pattern analysts consider the angle of impact to determine its origin and the amount of force behind it; variations in external forces can cause satellite drops. A point … A bloodstain can present itself differently depending on the situation and the material on which it appears, and bloodstains may be hard to examine on porous surfaces such as fabric, and may be distorted.
