For example, if someone claimed they were going to the aid of a victim, but there was suspicion of assault, blood pattern analysis (BPA) could assist in determining any involvement that person may have had.

Hau Forensics can also offer an informed expert opinion if the circumstances surrounding the mode of blood transfer are in dispute. Our experts are experienced in recovering samples from different backgrounds, maximising potential testing opportunities from the very slightest traces of evidential material. In addition, BPA can determine which area of staining is likely to provide the most informative result if sampled for DNA testing.
