Mutant City Blues - Manhattan
Evidence Collection and Handling
Although HCIU possess the expertise and equipment (or Mutant Powers) to examine and process evidence, actual evidence collection is handled by civilian criminalists detailed to the Crime Scene Processing Unit. Although you can count on them to collect obvious evidence, a good detective always remains at the scene to request the bagging and tagging of all relevent materials.
You must perform all necessary paperwork when removing or accessing materials from Evidence Storage, to thoroughly document the whereabouts of each piece of evidence that might be introduced in court at all times. This process flow is called The Chain of Custody. Defense lawyers win acquittals by successfully calling into question the Chain of Custody. When this chain is broken, police careers go along with it.
