Chapter 1018: Investigation

"Victim Yu Mingguo. Divorced. His wife raises a 12-year-old child alone and has basically no contact with the victim in daily life."

"Yu Mingguo lived alone and had no fixed girlfriend. After searching his residence and office, no bloodstains or effective biological samples were found, and it was initially determined that it was not the first crime scene."

"The last few calls Yu Mingguo made were to his business partners. The last location where his signal disappeared was also in Yu Mingguo's own shop. The surveillance in the shop only faced the front door and found nothing."

"In addition, Yu Mingguo operated a cake shop and a Hunan restaurant outside the campus, and also sold alcohol, all of which had dismal business. He had conflicts with many people and had been administratively punished for fighting after drinking."

Jiang Yuan's autopsy hadn't been finished yet, and Wang Chuanxing brought the preliminary investigation report over.

After vomiting, the much more comfortable female reporter Ye Xin huddled in the corner, copying the answers of other reporters. Hearing Wang Chuanxing's report, she immediately stood up.

She is a reporter who often reports on police activities. She not only has various qualification certificates but has even filmed documentaries for the police force with the crew, so she knows the working mode of the general police force.

Ordinary police handling cases are actually multi-threaded, that is, a policeman holds multiple cases in his hands at the same time, and he advances whichever case has an opportunity.

A special task force, as the name suggests, can abandon this multi-threaded mode and focus wholeheartedly on one case.

However, a special task force can focus on one case itself, which does not mean that other units have the obligation to cooperate, or that they are too busy with the cases in their own hands, and in multi-threaded work, if you have cooperation requirements, you can only be ranked in multi-threaded tasks, becoming a part of it. It is impossible to turn the surrounding units into a special task force just because you are a special task force.

Therefore, assistance tasks are often time-consuming, and it is not uncommon for them to delay work or even miss opportunities.

Precisely because of this, special task forces often have to send people to other places to investigate themselves, because if you don't go on a business trip, the local criminal police team will not put your needs in the main position. It's good enough to give assistance.

But the treatment of Jiang Yuan's special task force is obviously different.

The residence of the victim Yu Mingguo is in Changyang City. If people were sent from Ningtai County, plus the coordination time, it would be good to find the location in four or five hours.

Jiang Yuan directly asked the Changyang Criminal Police Detachment to assist in the investigation. A phone call went over, and the other party not only investigated the residence and office but also sent scene investigation personnel to conduct a preliminary investigation. Otherwise, they wouldn't dare to say that "it is not the first crime scene."

In Ye Xin's concept, even if it is a case supervised by the provincial department, it is very difficult to complete such work with such efficiency.

Ye Xin couldn't help but take out her mobile phone and took a few half-length photos of Jiang Yuan.

She didn't take photos of the autopsy table. The impact of that scene was too great. Ye Xin hadn't practiced it before, and didn't want to practice it in the future.

Jiang Yuan was still doing the autopsy, and his movements had no deformation at all.

Wang Chuanxing, who had just completed the report, stood by, not in a hurry.

The criminal police of the cold case special class gathered together and discussed in a low voice.

Speaking of which, this case hasn't even established a special task force, so naturally, it belongs to the ordinary cases of the cold case special class.

Shen Yaowei said first: "In the environment where the victim is, business-related conflicts are the main contradictions, right? He made his last few calls to business partners. These business partners should be listed for investigation."

Meng Chengbiao reminded: "The person is dead, and the money will be even harder to get back."

"Maybe it was a moment of anger." Shen Yaowei said.

"It's possible." Meng Chengbiao paused: "Love-related killings should also be considered. Although he didn't have a fixed girlfriend, for someone who opened two or three shops, even if he was losing money, it wouldn't be difficult to find a partner. We should investigate his situation in this regard."

"Either it's a married woman, or it's prostitution. It's really possible to have a love-related killing." Liu Wenkai didn't know when he walked over. Hearing the discussion inside, he immediately joined in actively.

Liu Wenkai is now the captain of the Ningtai County Criminal Police Brigade. Theoretically, the Taihe Working Group is a unit that is balanced with it, but Liu Wenkai is not willing to be so estranged, and instead takes the initiative to come over to visit.

Jiang Yuan saw this, took the initiative to greet Liu Wenkai, and said: "If it's a love-related killing, what is Captain Liu's suggestion?"

Liu Wenkai came to his spirit and said seriously: "If it's a love-related killing, prostitution is the best to check. Either it's a long-term relationship that has produced conflicts, or it's a conflict caused by the prostitution fee. No matter which one it is, just check the flow of money. Either it's a transfer, or it's a cash withdrawal. In our Shannan Province, we won't use Bitcoin."

Liu Wenkai paused and said: "If it's a married woman, it's also simple. As long as you find the person, either the husband killed, the wife killed, or the couple killed together. Finding people is also simple. Check the contact information carefully and match it with the phone number. Calls always have to be made, but people usually chat with chat software now. It is possible that they deliberately don't use WeChat, so you have to check a few more software."

"Why must the victim's partner be a married woman?" Wang Chuanxing's question was also the question of many people at the scene, and they all looked over.

Liu Wenkai curled his lips and said: "If the other party is single, even if they don't aim for marriage, they won't make it public, but it's impossible to have no traces at all. At the very least, there won't be no traces on the victim's side. A 43-year-old man, whose business is dismal, hanging on to people... he doesn't look handsome, right?"

"Maybe he's very good at PUA or something?" Shen Yaowei raised a point.

"It doesn't affect it. PUA always needs mutual contact, right? And, given the victim's situation, unless the woman asks, otherwise, he doesn't need to hide it. In other words, Yu Mingguo is in the lower position in the relationship. How could a PUA be in the lower position." Liu Wenkai talked eloquently, very confidently, and said: "However, according to my observation, the probability of Yu Mingguo prostituting is greater. He doesn't look like he has the ability to talk to a married woman."

"Captain Liu is wise." Shen Yaowei was convinced.

Jiang Yuan saw this and said: "Then for this love-related killing route, can I trouble Captain Liu to investigate?"

"No problem!" Liu Wenkai immediately agreed.

The Taihe Working Group has a staff of 40, and it hasn't been fully staffed yet. It is absolutely insufficient to investigate homicide cases by itself. Therefore, it is reasonable for the Ningtai County Criminal Police Brigade to cooperate.

It's impossible to say that because Huang Qiangmin no longer holds a concurrent post, they become estranged. Liu Wenkai came over this time to adjust the working mode of both sides.

"For business conflicts, if it's this line, I can narrow the scope." Jiang Yuan said while taking off his gloves, and said to Wang Chuanxing: "The victim's time of death is initially estimated to be between 15 and 18 days ago. You calculate it and see how to investigate it appropriately."

"You can do a space-time intersection of the mobile phone. In addition, business partners who called the victim before his death but didn't take the initiative to call or send text messages after his death should also be included in the suspect list." Wang Chuanxing grew up very quickly and already knew how to come up with a plan himself.

Jiang Yuan nodded in approval, and everyone immediately got busy.

The female reporter stared with colored contact lenses, and the case-handling mode of Jiang Yuan's cold case special class obviously exceeded her expectations, and in her mind, she had already begun to imagine the report, and the scene after the report. ===== CHAPTER 1019 =====
