Chapter 559: Chapter 529 Suspicious Laboratory_1

Liu Yongxin's face showed excitement, and he kept waving at a junior criminal police officer next to him, signaling for him to hurry and call people over.

"Call through the intercom; tell the folks from Technical to get here."

The junior police officer nodded frantically, repeated Mr. Zhao's words into the intercom, and in moments everyone rushed over. Liu Yongxin, panting, squatted beside Mr. Zhao.

"What did you find?"

"Footprints. Although they're not complete, the pattern is so distinctive. I think it's the same as the one found in Mr. Qu's flower bed. And looking at the position, this guy has a keen eye. He said it's a pit made from peeing, and I found it indeed looks like it. Mr. Liu, take a look. According to the position where the footprints were left, this person must have been peeing facing the slope."

Mr. Yang also squatted down, took off his mask, and sniffed closely at the spot.
