"The woman is Zhou Yang's mother, the man... has been watching from behind."
In the footage, after Zhou Yang took the money and left, the man basically moved along, walking not far behind Zhou Yang's mother.
Then they ran into Zhou Yang's father at the supermarket entrance.
Afterward, he followed the direction Zhou Yang left and disappeared from the footage.
"Brother Hui, the video doesn't show the shoes' soles clearly."
The most important reason Lu Chuan suspects this person is due to the wear on the edge of his leather shoes, which is similar to the wear found on the footprints at the scene.
Therefore, Lu Chuan most wants to see the soles of this man's shoes.
Lu Chuan has done assessments analyzing the footprints at the crime scene and has a very deep memory of the shoe pattern.
Thus, once he sees this man's shoe sole pattern, Lu Chuan can determine if this man was present at the scene.
However, for Zhang Hui, there's no need to be so troublesome.
