This isn't something that gets written into the case files. Jiang Yuan, grasping the key points, asked, "So the case drew a lot of attention as soon as it came out?"
Pang Jidong replied, "You could say that. But generally speaking, it's an area where the middle class can afford to live, and the rich are willing to live as well, so it's supposed to be a very safe neighborhood. Actually, we have a hypothesis, because there were surveillance cameras around the area at that time, any vehicle entering or leaving would have the risk of being exposed. We suspect that the killer might also live in this area."
Jiang Yuan neither agreed nor disagreed. This also counted as reasoning, though not very rigorous. Compared to Liu Jinghui's reasoning, it lacked competitiveness and felt more like a guess.
