Note: the "agent" the title refers to has nothing to do with an AI/LLM agent. Originally I thought this had something to do with an AI agent, as if someone put an AI agent in charge of identifying dark web pictures for clues. It's a good story nevertheless and I'm glad the victim was rescued, but nothing to do with AI/LLMs.
The term "agent" with regards to law enforcement substantially predates "agent" in the context of AI.
