章 411: Chapter 378 Supply Chain

Liu Jinghui speculated on the identities and relationship between Number One and Number Two in various ways.

The most plausible guess was that the two were old acquaintances who met by chance, but Number Two, for reasons like drug use or something else, developed a murderous intent.

Jiang Yuan did not oppose his speculation, but when it came to the actual case investigation, Jiang Yuan still preferred to follow the evidence.

The current evidence was the surveillance footage.

Surveillance in Ningtai County was quite comprehensive. The density in the urban areas might not be higher than in Changyang City, but because of the newer and fully equipped systems, which were configured more rationally, it was definitely superior to that of Changyang City.

Additionally, it was extremely convenient to have a group of people pulled together to view footage for case-solving purposes.
