Why OCC Investigations Matter

Over the past three decades, I’ve worked with investigators in dozens of agencies. What I’ve learned is this: the difference between an investigation that changes an institution and one that’s forgotten in six months is methodology.

OCC’s investigative approach is designed to be thorough, defensible, and consequential. This is why courts cite our findings. This is why institutions respect our citations. This is why our violations actually change behavior.

Let me walk you through what makes OCC investigations different.

The Foundation: Standards-Based Investigation

Every OCC investigation rests on clear legal authority. We don’t investigate because we think something might be wrong. We investigate when we have statutory authority and documented evidence suggesting violation of law.

This matters because:

  • Our investigations can withstand legal challenge
  • Our authority is recognized by courts
  • Institutions can’t easily dismiss our findings
  • Compliance is legally enforceable

Chain of Custody Discipline

From the moment an investigation begins, we maintain rigorous chain of custody:

  • Every document is logged
  • Sources are documented
  • Access is tracked
  • Nothing is lost or misfiled
  • Evidence cannot be challenged as tampered

Why this matters: Physical evidence collection is worthless without chain of custody. Our evidence holds up in court because we’ve documented every step.

Phase 1: Pre-Investigation Assessment

Before we commit investigative resources, we conduct careful assessment.

Preliminary Review

We examine:

  • The nature of the complaint or evidence
  • Whether OCC has jurisdiction
  • Whether we have sufficient evidence to proceed
  • What specific legal violations may be present
  • What investigative resources will be required

What we’re asking:

  • Is this worth investigating?
  • Will we find anything?
  • Can we prove what we find?

Risk Assessment

We evaluate:

  • What institutional failures might exist
  • What vulnerable populations might be affected
  • What documentation likely exists
  • What timeline is appropriate
  • What investigative team we’ll need

This assessment determines whether we investigate and how.

Phase 2: Investigation Planning

Detailed Investigation Plan

Once we decide to investigate, we create a detailed plan:

  • Specific allegations to be investigated
  • Legal authorities relevant to each allegation
  • Evidence we expect to find
  • Interviews we’ll conduct
  • Document reviews required
  • Timeline for investigation
  • Required expertise on investigative team

This plan is crucial because:

  • It focuses the investigation
  • It prevents wandering or bias
  • It documents what we intended to investigate
  • It allows oversight of investigative decisions

Team Assembly

We assemble teams with:

  • Relevant legal expertise (prosecutor, judge, attorney)
  • Relevant operational expertise (court experience, detention experience)
  • Investigative expertise (experience in evidence collection)
  • Geographic diversity (preventing local bias)
  • Complementary personalities and perspectives

Why this matters: The best investigations benefit from diverse perspectives. We intentionally assemble teams where members will challenge each other.

Phase 3: Evidence Collection

Document Review

Our document reviews are systematic:

  • We review all relevant documents, not selected ones
  • We look for what’s present and what’s missing
  • We verify document authenticity and chain of custody
  • We compare documents to verify consistency
  • We identify patterns and anomalies

Key discipline: We take notes during review that document what we looked at, what we found, and why it matters. These notes are then reviewed by other team members.

Interviews

When we interview staff, detainees, or witnesses:

  • Interviews are documented (recorded when possible)
  • Questions are consistent across similar interviews
  • Follow-up questions explore contradictions
  • Interviewers are trained in proper interview technique
  • Interviews are reviewed by team members not present

What we avoid:

  • Leading questions
  • Suggestive language
  • Interviews by investigators with obvious bias
  • Surprise questions designed to trap
  • Pressure or coercion

Physical Evidence

When physical evidence is involved:

  • Evidence is photographed and documented
  • Chain of custody is maintained
  • Specialized expertise is used for technical evidence
  • Multiple investigators examine evidence independently
  • Findings are documented and reviewed

Phase 4: Analysis and Synthesis

Individual Analysis

Each team member conducts independent analysis:

  • What does the evidence show?
  • What legal standards apply?
  • What violations appear to have occurred?
  • What questions remain?
  • What additional evidence is needed?

Members document their analysis in writing.

Team Review

The team then meets to:

  • Compare findings from independent analyses
  • Discuss areas of disagreement
  • Identify evidence gaps
  • Determine additional investigation needed
  • Explore alternative explanations

This is crucial: When investigators agree without discussion, we ask hard questions. Agreement after healthy disagreement is more credible.

Our lawyers review:

  • Whether evidence supports legal conclusions
  • Whether procedures were properly followed
  • What legal authorities support findings
  • What citations will be issued
  • What remedial actions to recommend

Phase 5: Multi-Layer Review Process

This is where OCC investigations become powerful.

Investigative Team Review

The team that conducted investigation reviews findings:

  • Do findings match evidence?
  • Are recommendations appropriate?
  • Are conclusions clearly supported?
  • Can we defend this in court?
  • What holes remain?

Independent Review Panel

A separate panel of commissioners reviews:

  • The investigation process
  • The evidence and its quality
  • The legal analysis
  • The conclusions and recommendations
  • Whether additional investigation is needed

This panel hasn’t been involved in the investigation, so they bring fresh perspective.

Our general counsel conducts legal review:

  • Are procedures followed?
  • Are findings legally sound?
  • Are citations appropriate?
  • Can we defend findings if challenged?
  • What language should be used?

Executive Review

Leadership reviews:

  • Overall quality of investigation
  • Appropriateness of conclusions
  • Reasonableness of recommendations
  • Consistency with previous cases
  • Message being sent by this investigation

Only after all these reviews do we issue final findings.

Phase 6: Documentation and Reporting

Investigation Report

We prepare detailed reports showing:

  • What we investigated and why
  • What evidence we examined
  • What interviews we conducted
  • What findings we reached
  • What legal authorities support findings
  • What recommendations we make
  • What timeline we expect for compliance

Citation Language

Citations are precise:

  • Specific legal authorities referenced
  • Specific evidence cited
  • Precise description of violation
  • Clear statement of what must be corrected
  • Reasonable timeline for correction

The Disciplines That Make Investigation Credible

1. Documentation Discipline

Everything is documented:

  • Investigation plan is documented
  • Evidence examination is documented
  • Interview notes are documented
  • Analysis is documented
  • Review comments are documented
  • Decision-making is documented

Why this matters: Documented investigations are defensible investigations. If we can’t document it, we don’t claim it.

2. Objectivity Discipline

We work hard to prevent bias:

  • Investigators are rotated when bias is possible
  • Teams are diverse
  • Review panels include different perspectives
  • Alternative explanations are explored
  • Evidence is examined carefully

What we know: Investigators unconsciously bias investigations. We account for this through process.

3. Evidence Discipline

We maintain standards for evidence:

  • Sufficient evidence is required before claiming findings
  • Evidence is examined by multiple people
  • Expert evidence is reviewed by qualified experts
  • Chain of custody is maintained
  • Authenticity is verified

Standard: We only claim findings we could defend in court.

We understand our legal authorities:

  • We don’t exceed our statutory authority
  • We apply law correctly
  • We cite appropriate authorities
  • We follow procedures required by law
  • We respect appellate precedent

Standard: Courts consistently uphold our findings because we apply law properly.

5. Procedural Discipline

We follow our own procedures:

  • Investigation plan guides investigation
  • Reviews are completed before findings are issued
  • Documentation is completed as work happens
  • Nothing is added after the fact
  • Procedures are consistently followed

Why this matters: If we don’t follow our own procedures, why should institutions follow theirs?

When We Find Nothing

Sometimes OCC investigations conclude that violations didn’t occur. This happens when:

  • The evidence doesn’t support violation claims
  • Legal authority doesn’t apply
  • Alternative explanations are more credible
  • Institutional procedures were adequate
  • Decisions were reasonable under the circumstances

This is important: An investigation that finds no violations is honest investigation. Some of our most credible investigations are ones that could have found violations but didn’t, because evidence didn’t support it.

Why This Approach Creates Consequences

Institutions change behavior because of OCC investigations because:

  1. Findings are thorough - We’ve examined everything, not just selected items
  2. Findings are legal - Citations rest on clear legal authority courts respect
  3. Findings are defensible - We could defend them if challenged
  4. Findings are consequential - Institutions understand we mean what we say
  5. Reviews are real - Multiple reviewers aren’t just rubber-stamping
  6. Process is rigorous - We do the hard work of investigation properly

The Cost of Rigor

This approach requires:

  • Experienced investigators and lawyers
  • Time (8-12 weeks per investigation)
  • Meticulous documentation
  • Multiple reviews
  • Willingness to conclude “not founded” when evidence requires it

It’s expensive. But findings that change institutions are worth the cost.

For Institutions Reading This

If you’re an institutional leader concerned about OCC investigation, understand this: we investigate thoroughly because we take your institution seriously.

Our rigor means:

  • We’ll find problems if they exist
  • We won’t find problems that don’t exist
  • We can defend what we claim
  • Our recommendations are thoughtful
  • Our timeline is reasonable

Cooperation with thorough investigation is in your interest. OCC investigation is more likely to find and address real problems than to create false ones.

Prepare for investigation by fixing your own problems first. That’s the best defense against unwanted findings.

But if we do find violations, understand that our findings rest on rigorous investigation you can trust.

That’s the OCC difference.
