A study of case dynamic by fingerprints' fragments analysis.
Fingerprints are an extremely helpful tool for investigators as they can lead to personal identification through the observation and comparison of the characteristic minimal elements present in their structure. As forensic scientists and not only like investigators we have considered the hypothesis they may also be useful to study the dynamic of a gun shot murder in order to realize how the event took place. We have detected the presence of some papillary crest impressions on a gun which had shot and killed a person: afterwards, we have studied how those traces were oriented on the gun itself in order to determine how it was grasped, which led us to understand the murderer's behaviour on the crime scene.
