The added value of behavioural information in crime scene investigations.

Forensic and behavioural science are often seen as two different disciplines. However, there is a growing realization that the two disciplines should be more strongly integrated. Incorporating psychological theories on human behaviour in forensic science could help solving investigative problems, especially at the crime scene.

Visual characteristics for sequencing of overlapping bloodstain patterns.

The deposition sequence of overlapping bloodstain patterns can be valuable reconstructive information. A formal method for sequencing overlapping bloodstain patterns has yet to be published. We present a method for sequencing overlapping transfer and drip stains using visual characteristics.

Improving the point of origin determination in bloodstain pattern analysis.

In bloodstain pattern analysis, it is important to know the point of origin (PO) of an impact pattern. This point can be estimated by means of the stringing method, the tangent method, or by commercially available computer programs. In this study, the accuracy of two computer programs was investigated under different conditions.

Enhancement of muddy footwear impressions.

Methods for chemical enhancement of muddy footwear impressions were compared in order to differentiate between utilisation at the scene of crime, the local (regional) police laboratory and the Netherlands Forensic Institute (NFI)

Enhancement of footwear impressions in blood.

Methods for chemical enhancement of footwear impressions in blood were compared in order to make a separation between utilization at the scene of crime, the local (regional) police laboratory and the Dutch Forensic Science Laboratory (DFSL).
