Upon concluding an administrative investigation, a special agent
recommending prosecution must prepare a special agent's report (SAR) that details
the investigation, its results, and the agent's recommendations. After review
within CID, the SAR, together with the exhibits, is reviewed by District Counsel.
When prosecution is deemed warranted, District Counsel prepares a criminal
reference letter (CRL), that discusses the nature of the crime(s) for which
prosecution is recommended, the evidence relied upon to prove it, technical
aspects and anticipated difficulties of prosecution, and the prosecution
recommendations themselves.
