Notes From A Criminal Investigation 8 Chapter 23

When encountering a murder case, many investigators' first reaction is to suspect the people around them. Owen had just investigated the case of Qiu Hongbing's wife murder. When faced with Zhao Daijun who was murdered at home, he did not think about the problem according to the investigation direction of the Huzhou Criminal Police Detachment, but instead turned his attention to the people around Zhao Daijun.

Jiang Keyang asked: "If it was Yang Mei, how did she get the drugs? How do you explain the similarities between the other two cases and this one?"

Owen said: "On the day of the crime, the other two cases had not yet occurred. We can temporarily put aside the latter two cases and reconstruct the scene purely from this case."

Jiang Keyang was surprised and said: "After linking the cases together, there are more clues, which is why we are investigating the cases together. Why do you want to start with Zhao Daijun's case alone?"

Owen explained: "In fact, the evidence linking the three cases is not very strong, it can be regarded as a soft link. The only common point of the three cases is the drug, and the other similarities are summarized by us. In fact, there are more differences that have been overlooked. In order to investigate this case, the Huzhou police dug up the drug sales chain in Huzhou, sentenced and detained 31 people, but did not find any clues that match this case. If we still focus on drugs and fallen women, we will definitely reach a dead end. Based on this, we temporarily regard the Zhao Daijun case as an independent case, starting with his social relations and behavioral trajectory, and conducting an in-depth investigation."
