SIU Field Investigation Case Plan and Log

This template is for documenting a special investigations unit field case from the initial assignment through final findings and sign-off. It helps investigators record the investigation objective, planned activities, interviews, scene observations, digital review, corroboration, and referral decision in one place. Use it when you need a defensible record that can support an internal escalation, claim decision, or law-enforcement referral.

Use this template when the matter requires field work, witness interviews, evidence handling, or a documented referral decision. A simple incident note is usually enough for routine observations or low-risk follow-up, but not for cases where facts may be disputed or evidence preservation matters. If the case could end up in legal review, this log gives you a cleaner chain of reasoning and a clearer audit trail.

The assigned SIU investigator should complete the log, with supervisor or case manager approval where required. If the investigation involves scene access, privacy-sensitive records, or external referrals, legal, compliance, or claims leadership may also need to review parts of the file. The key is that one accountable owner keeps the record current and distinguishes observed facts from assumptions.

Update it as each investigative step occurs, not after the case is closed. Intake, interviews, scene work, digital review, database checks, and referral decisions should each be recorded while the details are fresh. Delayed documentation is a common source of missing timestamps, incomplete source attribution, and avoidable credibility issues.

Yes, the structure includes a place to record applicable legal, privacy, and company authorization review before field activity begins. That matters because SIU work often touches public records, social media, workplace access, and internal databases, all of which may have limits on use and retention. The template helps you note those constraints without turning the log into legal advice.

It helps prevent vague objectives, undocumented interview dates, missing source URLs, and scene notes that mix facts with interpretation. It also reduces the risk of failing to record why a referral was or was not warranted. Another common issue is skipping corroboration notes, which makes it harder to explain conflicting statements later.

Yes, the structure is flexible enough for insurance SIU, HR misconduct, benefits fraud, vendor fraud, or policy-violation cases. You can rename fields, add case-specific evidence types, or include organization-specific approval steps and escalation paths. The core workflow should stay the same: plan, document, corroborate, decide, and sign off.

Ad hoc notes are easier to start but harder to defend because they scatter evidence, timestamps, and decisions across multiple places. This template keeps the investigation narrative in one sequence, which makes review, audit, and handoff much easier. It also reduces the chance that a critical detail is lost when a case moves between investigators or managers.
