Affect of impact angle variations on area of origin determination in bloodstain pattern analysis.

The estimation of the location of the area of origin of a blood source is of major importance within bloodstain pattern analysis. Given this, it is particularly important to establish the accuracy of such estimations. This study examines error rates by investigation of alpha angle inaccuracies of upward directional stains and compares a virtual bloodstain pattern model to real bloodstain patterns.
