Le sang qui parle

Blood drops and patterns are not just mess — they physically reconstruct what happened through bloodstain pattern analysis (BPA). They help answer:- Where the injuries occurred (location of origin of the blood spatter)- How the injury was inflicted (type of weapon, amount of force, number of blows)- In what sequence events unfolded- Who was where (position of victim vs. attacker, post-injury movement)- Suicide, accident, or homicide? (very often the decisive factor)
