What type of evidence might be found as a result of hit-and-run accidents?

In hit-and-run accidents, blood can often be a significant type of evidence found at the scene. When a pedestrian is struck by a vehicle, it is likely that the impact may cause injuries resulting in blood spillage. This biological evidence can provide crucial information, such as the presence of the victim and potentially the dynamics of the accident. Analyzing blood samples can also lead to DNA identification, which helps in establishing the identity of the victim or even tracing the vehicle involved in the hit-and-run if bodily fluids are collected from the vehicle.

Other options like tool marks, fabric samples, and shoe prints might not be as directly related to the circumstances of a hit-and-run. For example, tool marks typically relate to burglary or other crime scenes involving tools. Fabric samples might be relevant if there was contact between the vehicle and a person, but they are less common than blood evidence, which is more prevalent in such accidents. Shoe prints can sometimes be found, particularly in scenarios where a pedestrian interacts with the scene, but blood remains the most crucial and telling evidence in this context.
