The pattern of blood staining is often critical in establishing what actions led to the deposition of the blood. This can help to resolve conflicting accounts by determining, for example, whether someone assaulted a victim or was simply going to their aid. Pattern analysis is also fundamental in deciding what samples to take for DNA analysis in order to establish from whom the blood could have originated.
