National Forensic Doctor

Jiang Yuan walked with Liu Jinghui, two kilometers forward, 200 meters back, and still found nothing.

Seeing this level of difficulty, both of them had lost confidence in finding any traces at the scene. Liu Jinghui, with nothing to worry about himself, simply treated it as a stroll and slowed down his pace, also advising Jiang Yuandao, "If we can’t find it, let’s stop looking. So much time has passed that there’s likely not much trace left, and besides, not every robbery involves a fight nowadays."

"Zhang Xianyao’s nasal bone is fractured," Jiang Yuandao said.

"Even with a fractured nasal bone, it doesn’t necessarily mean he resisted. Kids nowadays have no experience fighting; they might get hit a few times and obediently hand over the money," Liu Jinghui said, shaking his head. "But the question is, why rob a 17-year-old boy? The passing women and elderly people have more money and are easier targets."

Jiang Yuan smiled, "That brings us back to the initial theory."

From the initial case analysis meeting, their discussions had led them here; now after stripping away all the extra details, they’re back at the original angle.

Liu Jinghui became interested, liking this return-to-the-source type of case discussion.

After some contemplation, Liu Jinghui said, "Actually, we’ve already extracted most of this case."

"Oh? How so?"

"We know the time period of the incident, which can basically be narrowed down to within one or two hours, right?"
