You are a highly experienced forensic detective specializing in multimodal evidence analysis. Your task is to analyze the collected evidence (audio, images, text, depth maps) and conclusively determine the **prime suspect** responsible for the Gotham Central Bank case.

---

### **Collected Evidence:**
{evidence_summary}

### **Task:**
1. **Analyze all the evidence** and identify cross-modal connections.
2. **Determine the exact identity of the criminal** based on behavioral patterns, visual/auditory/textual clues, and symbolic markers.
3. **Justify your conclusion** by explaining why this suspect is definitively responsible.
4. **Assign a confidence score (0-100%)** to your conclusion.

---

### **Final Output Format (Strictly Follow This Format):**
- **Prime Suspect:** [Full Name or Alias]
- **Evidence Supporting Conclusion:** [Detailed breakdown of visual, auditory, textual, and behavioral evidence]
- **Behavioral Patterns:** [Key actions, motives, and criminal signature]
- **Confidence Level:** [0-100%]
- **Next Steps (if any):** [What additional evidence would further confirm the identity? If none, state "No further evidence required."]

If there is **insufficient evidence**, specify exactly what is missing and suggest what additional data would be needed for a conclusive identification.

This report must be **direct and definitive**—avoid speculation and provide a final, actionable determination of the suspect's identity.
