Quick Guide
  • AI Interrogation Case 004 rewards careful evidence comparison rather than fast dialogue choices.
  • Read every statement before selecting a contradiction or accusation.
  • Build the timeline first, then connect physical clues to each testimony.
  • Use proof strategically instead of presenting evidence at random.
  • Save before the final choice if your version allows manual checkpoints.

AI Interrogation How to Solve Case 4: Core Method

Case 004 is easiest to approach as a logic investigation. The objective is not to choose the most suspicious response immediately. Instead, identify the statement that cannot fit the known timeline, then support your challenge with the strongest matching evidence.

The exact wording of prompts may vary by release or language setting, but the reasoning pattern remains consistent: collect facts, separate observations from claims, and force the suspect to explain the contradiction.

Timeline First

  • Record when each event occurred.
  • Mark movements, calls, and transfers.
  • Treat unsupported time claims as provisional.

Evidence Match

  • Link each clue to one statement.
  • Prefer direct proof over assumptions.
  • Avoid presenting unrelated items.

Controlled Pressure

  • Ask neutral questions first.
  • Challenge one inconsistency at a time.
  • Save the accusation for the end.
Best Opening

Do not accuse the first character who appears nervous. Start with the testimony that conflicts most clearly with a recorded time, location, or physical clue.

Investigation ElementWhat to RecordWhy It Matters
TimeArrival, departure, and incident windowsExposes impossible movements
LocationClaimed position and confirmed positionSeparates alibis from verified facts
ObjectWho handled each relevant itemConnects testimony to physical proof
MotiveBenefit gained from the incidentHelps rank contradictions
WordingExact phrasing of each answerReveals evasions and changed claims

Case 004 Evidence and Timeline Setup

Before the main interrogation, organize the case into three layers: confirmed facts, suspect claims, and unresolved gaps. Confirmed facts come from reliable records or directly observed evidence. Suspect claims should remain unverified until another clue supports them.

A simple timeline prevents the most common mistake: using a true piece of evidence against the wrong statement. A clue may be important without proving the specific contradiction currently on screen.

Avoid Premature Accusations

A suspicious motive is not the same as proof. If a clue does not directly challenge the current statement, keep it in reserve and continue questioning.

Timeline CheckQuestion to AskUseful Result
Before the incidentWho could access the relevant area?Establishes opportunity
During the incidentWhich movements are confirmed?Narrows possible actors
Immediately afterWho changed behavior or location?Identifies useful follow-ups
Final accountDoes the story fit every known fact?Finds the contradiction

Use the following priority order when sorting clues:

  • Direct records: timestamps, messages, access logs, or visible event records.
  • Physical evidence: damaged objects, transferred items, or scene details.
  • Witness statements: valuable, but potentially incomplete or biased.
  • Motive clues: useful for context, but weaker than direct contradictions.
  • Emotional behavior: helpful for selecting questions, not for proving guilt.
Evidence StrengthTypical UseRecommended Action
Confirmed recordTests a time or location claimPresent early
Physical linkConnects a person to an objectPresent when ownership is disputed
Corroborating statementSupports an existing factUse after the central claim is made
Motive detailExplains possible intentUse near the conclusion
Suspicious behaviorSuggests a follow-upDo not use as sole proof

Step-by-Step Interrogation Route

Follow this route when Case 004 presents several similar answers. The sequence keeps the conversation focused and reduces the risk of wasting a strong clue before the suspect commits to a clear version of events.

1

Read the Full Testimony

Review every available statement before choosing a response. Note repeated phrases, precise time claims, and any answer that changes the subject instead of addressing the question.

2

Lock the Timeline

Compare the suspect’s claimed location with the confirmed sequence of events. Mark the first point where the account becomes difficult or impossible to maintain.

3

Ask for Clarification

Choose the neutral prompt that makes the suspect explain the disputed detail. This often reveals whether the problem is confusion, omission, or deliberate deception.

4

Present the Matching Proof

Select the evidence that directly addresses the contradiction. Avoid using a motive clue when the question concerns timing, and avoid using a location clue when the issue concerns ownership.

5

Confirm the Final Theory

After the testimony changes, review the complete chain: opportunity, action, evidence, and motive. Submit the conclusion only when each major link supports the same explanation.

Reliable Decision Rule

Choose the answer that explains the largest number of confirmed facts with the fewest unsupported assumptions. This is safer than selecting the most dramatic dialogue option.

Dialogue SituationCorrect ApproachCommon Mistake
The suspect gives a vague answerAsk for a specific time or locationAccusing without a fixed claim
Two statements conflictCompare them against confirmed evidenceTreating both as equally reliable
The suspect changes wordingHighlight the earlier wordingIgnoring the change
A clue seems importantIdentify which claim it provesUsing it because it feels suspicious
The final theory is incompleteRecheck the timelineSubmitting a motive-only conclusion

Common Case 004 Mistakes and Recovery Tips

Most failed attempts come from poor evidence order rather than a lack of clues. Presenting the right item at the wrong moment can produce a weak response, while selecting a hostile option too early may close off useful clarification.

When a response does not advance the case, return to the last confirmed statement and ask what it actually proves. The goal is to distinguish a contradiction from a simple detail that has not yet been explained.

If Your Attempt Stalls

Reopen the evidence list and find the earliest unresolved claim. Case 004 is usually easier after correcting the first timeline error instead of guessing at the final accusation.

Before the Final Verdict:

  • Confirm the incident timeline
  • Separate verified facts from suspect claims
  • Identify the strongest contradiction
  • Use evidence that directly supports the challenge
  • Explain opportunity, action, and motive together
MistakeWhy It FailsRecovery
Accusing from motive aloneMotive does not establish opportunityRecheck access and movement
Showing evidence randomlyThe suspect may not address the relevant claimMatch each clue to one statement
Skipping repeated dialogueSmall wording changes can reveal the key inconsistencyCompare earlier and later answers
Ignoring the timelineA plausible story may still be impossibleWrite the events in chronological order
Rushing the verdictOne missing link can weaken the conclusionReview the full evidence chain

Case 004 should be treated as a structured deduction puzzle. If the case still feels unclear, use a three-column note: claim, confirmed fact, and response needed. Fill the first two columns before choosing the next interrogation prompt.

Case 004 Final Answer Strategy and FAQ

The final decision should summarize the case rather than repeat the most suspicious line. A strong conclusion identifies who had the opportunity, what action is supported by the evidence, and why the testimony failed under examination.

If the game presents multiple final options, select the explanation that is supported by the timeline and direct proof. Do not treat a confession, nervous reaction, or apparent motive as sufficient unless the surrounding evidence confirms it.

Final Check

Before submitting, ask: “Which confirmed fact disproves the suspect’s version?” If you cannot name it, continue reviewing evidence instead of committing to the verdict.

Final Theory ComponentRequired QuestionStrong Support
OpportunityCould the suspect reach the relevant place or object?Confirmed access or movement
ActionWhat specific act is attributed to the suspect?Physical or recorded evidence
ContradictionWhich statement cannot be true?A direct timeline conflict
MotiveWhat reason explains the act?Consistent personal or case context
ConclusionDoes one theory fit the whole record?Few assumptions, complete chain

A clean solve does not require every clue to be equally important. Focus on the evidence that changes the investigation: the detail that rules out an alibi, links a suspect to the scene, or proves that the account changed.

Q: What is the best way to solve AI Interrogation Case 004?

Build the timeline first, identify the clearest contradiction, and present the evidence that directly disproves the suspect’s statement.

Q: Should I accuse the suspect as soon as I find a motive?

No. A motive is supporting context. Confirm opportunity, action, and a specific contradiction before choosing the final accusation.

Q: Which evidence should I present during the interrogation?

Use the clue that directly matches the disputed claim. Time evidence should challenge timing, location evidence should challenge an alibi, and object evidence should challenge ownership or handling.

Q: What should I do if my Case 004 answer is rejected?

Return to the earliest unresolved statement, compare it with the confirmed timeline, and use a clarification prompt before presenting another piece of evidence.
