How to Use AI Evidence Analysis
This guide shows you how to use AI to analyze evidence in your cases. You will learn to request categorization, review anomaly alerts, generate summaries, and verify AI suggestions.
You need the ai:analyze_evidence permission to use evidence analysis features. Most Detective and Supervisor roles have this permission by default.
What AI Evidence Analysis Does
AI evidence analysis helps you:
| Capability | What It Does |
|---|---|
| Categorization | Groups similar evidence items together |
| Anomaly Detection | Flags items that seem unusual or inconsistent |
| Summary Generation | Creates readable summaries of evidence collections |
| Gap Identification | Suggests evidence that might be missing |
| Connection Mapping | Shows relationships between evidence items |
The AI identifies patterns. You decide what matters.
Request AI Categorization
AI categorization groups your evidence by type, relevance, and characteristics.
Step 1: Open Evidence Tab
- Open your case
- Click the Evidence tab
- Click AI Analysis in the toolbar
Step 2: Request Categorization
- Click Categorize Evidence
- Select the evidence items to analyze (or choose "All")
- Click Analyze
The AI reviews each item and suggests categories.
Step 3: Review Categories
The AI presents categories such as:
| Category | Example Items |
|---|---|
| Physical - Weapons | Knife, firearm, blunt object |
| Physical - Biological | Blood sample, hair, DNA swab |
| Digital - Communications | Text messages, call logs, emails |
| Digital - Media | Photos, videos, audio recordings |
| Documentary | Receipts, contracts, notes |
| Scene Documentation | Crime scene photos, diagrams |
For each item, you see:
- Current category assignment
- AI suggested category
- Confidence level
- Reasoning
Step 4: Accept or Modify
For each suggestion:
- Click Accept to apply the AI's category
- Click Modify to choose a different category
- Click Skip to leave unchanged
AI categorization is a suggestion. Review each item to ensure accuracy. You know your case better than the AI.
Review Anomaly Alerts
AI anomaly detection flags evidence items that seem unusual or inconsistent with other items.
Step 1: Check for Alerts
- Open the Evidence tab
- Look for items with a yellow alert icon
- Or click AI Analysis then View Anomalies
Step 2: Review Each Anomaly
For each flagged item, you see:
| Field | What It Shows |
|---|---|
| Item | The evidence item flagged |
| Anomaly Type | What seems unusual |
| Details | Why the AI flagged this |
| Related Items | Other items involved in the pattern |
Common Anomaly Types
| Anomaly Type | What It Means |
|---|---|
| Timeline Inconsistency | Item timestamp does not fit the timeline |
| Location Mismatch | Item location differs from related items |
| Duplicate Potential | Item may duplicate another |
| Chain Gap | Missing step in chain of custody |
| Description Conflict | Description contradicts other evidence |
| Unusual Pattern | Item does not match expected patterns |
Step 3: Investigate the Anomaly
For each alert:
- Read the AI's explanation
- Check the related items
- Investigate whether this is:
- A real issue that needs attention
- A data entry error to correct
- A false positive to dismiss
Step 4: Resolve or Dismiss
- Click Investigate to add the item to your task list
- Click Note to add your assessment without action
- Click Dismiss to mark as reviewed (not an issue)
All actions are logged for audit.
Generate Evidence Summaries
AI summaries compile your evidence into readable narratives for reports and briefings.
Step 1: Request a Summary
- Open the Evidence tab
- Click AI Analysis
- Click Generate Summary
Step 2: Choose Summary Type
Select the type of summary you need:
| Type | Best For |
|---|---|
| Complete Inventory | Full listing of all evidence |
| Executive Summary | Brief overview for supervisors |
| Timeline Summary | Evidence organized chronologically |
| Category Summary | Evidence grouped by type |
| Lab Status Summary | Focus on items at or pending lab |
Step 3: Select Scope
Choose what to include:
- All Evidence — Everything on the case
- Selected Items — Only items you select
- By Category — All items in specific categories
- By Date Range — Items from a time period
Step 4: Review the Approval Card
Because generating a document is a significant action, you see an approval card:
| Field | What It Shows |
|---|---|
| Action | Generate evidence summary |
| Type | Summary type you selected |
| Scope | What will be included |
| Risk Level | Usually Low or Medium |
Click Approve to generate the summary.
Step 5: Review and Edit
The AI generates a draft summary. Review it for:
- Accuracy — Are facts correct?
- Completeness — Is anything missing?
- Clarity — Is it easy to understand?
- Tone — Is it appropriate for the audience?
Make edits as needed before sharing.
AI-generated summaries are starting points. Always review and verify before using in official reports or court documents.
Verify AI Suggestions
Every AI analysis requires your verification. Here is how to verify effectively.
Check Facts Against Source
For any AI statement:
- Identify the claim
- Find the source evidence
- Verify the claim matches the source
Example:
- AI says: "Blood sample collected at 3:45 PM"
- Check: Open the evidence item, verify the timestamp
Look for Missing Context
AI may miss context you know:
- Prior history with subjects
- Information from interviews
- Details not in the system
- Your professional assessment
Add this context to your notes.
Trust Your Experience
If something seems wrong:
- Investigate further
- Check the source data
- Note your concerns
- Do not accept AI output that contradicts your training
Document Your Verification
When using AI analysis in reports:
- Note that AI assisted with analysis
- Document your verification steps
- Add your professional assessment
- Sign as your work (because it is, after verification)
Best Practices
Regular Analysis
Run AI analysis periodically, not just at case end:
- After adding significant evidence
- Before briefings
- When preparing reports
- When the case seems stuck
Cross-Reference
Use AI analysis alongside manual review:
- AI catches patterns
- You catch context
- Together you miss less
Act on Anomalies
Do not ignore anomaly alerts:
- Most are worth investigating
- Document why you dismiss any
- Patterns of dismissed alerts may indicate a real issue
Save Summaries
Keep generated summaries:
- They show investigation progress
- Useful for case reviews
- Help with handoffs
Troubleshooting
AI Analysis Button Not Available
- Check that you have
ai:analyze_evidencepermission - Verify you have at least one evidence item on the case
- Try refreshing the page
Analysis Taking Too Long
For large evidence collections:
- Select a subset of items
- Analyze in batches
- Contact support if consistently slow
Anomaly Alerts Seem Wrong
- Check the evidence data for errors
- Review the AI's reasoning
- Dismiss with a note explaining why
- Report persistent false positives to admin
Summary Does Not Match Evidence
- Check that all evidence is current
- Verify items were not modified after analysis
- Re-run the analysis
- Manually correct the summary
