VeriScene: Reconstructing Crime Scenes from Legal Evidence via World-Model Agent
Researchers present VeriScene, a world-model agent that reconstructs crime scenes from forensic photos and witness statements with traceable, physically plausible output.
VeriScene orchestrates a world model to fuse forensic photographs and witness statements of varying reliability into cited narratives and physically plausible re-enactment videos. On a 25-scenario benchmark with planted unreliable testimony, it reaches 0.9014 evidence coverage and 0.7217 factual consistency on 20 test scenes. It outperforms an end-to-end multimodal-LLM baseline by 20.35% in factual consistency and 34.88% in temporal coherence at USD 1.82 per scene.
- Agent-led auditing loop keeps every claim traceable to source evidence
- Probe rollouts with corrective constraint injection verify hypothesized event dynamics
- Renders offence re-enactments from a fused keyframe
- Generalizes across four LLM orchestration backends

1 min read at arxiv.orgWorld models take multimodal inputs like text, photos, and diagrams to generate dynamic scenes in accordance with the laws of physics, thus opening a compelling application: fusing multimodal legal evidence to re-create a crime scene and re-enact how an offence could have been committed.
