Many crimes that are committed may require that a bloodstain pattern analysis is performed. Typically, a law enforcement agency or detective will be responsible for consulting with the team that will be performing the analysis.
The Preliminary Steps
When a crime is reported, the scene where the incident occurred must be carefully sealed off. The blood that was shed, the positioning of a victim's body, the victim's personal possessions, and the furnishings or other items that are within the crime scene must be preserved.
