What does 'lead snowstorm' refer to in crime scene investigation?

In crime scene investigation, the term 'lead snowstorm' specifically refers to the presence of white fragments of lead that can be found around areas where tissue is missing, typically as a result of a gunshot wound. These fragments are remnants from bullets that have shattered upon impact, scattering tiny lead particles into the surrounding area. This phenomenon can provide significant investigative leads, as it points to the location of a shooting and may help forensic teams understand the dynamics of the event, including the type of ammunition used and the distance from which the shot was fired. By analyzing these lead fragments, investigators can glean important information that may aid in reconstructing the sequence of events in a crime. This element of physical evidence is crucial, as it connects the victim to the crime scene and potentially identifies the weapon that was used.
