1. Explain the terms area of convergence and area of origin and explain what each term reveals to an investigator. The area of convergence of an impact spatter pattern is the area the individual stains emanated from on a two-dimensional plane. The area of origin of a bloodstain pattern in three-dimensional space may represent the position of the victim or suspect when the stain-producing event took place. These areas can determine and reveal to an investigator the direction of force‚ angle of impact
