Notes From A Criminal Investigation 7 Chapter 2

"He is getting more and more powerful now. I never thought that Grandet would become Professor Ge. Everything is possible. This is really not a lie."

Li Jianwei disinfected his hands again. He had disinfected his hands after checking the head. Although he did not touch the body parts again, he still disinfected them repeatedly with alcohol. Many professions have occupational diseases, and this is Li Jianwei's occupational disease.

The police walked along the river for more than an hour, and at ten o'clock, they found two more black bags. The body parts in the four black bags weighed only 34 kilograms, and it was obvious that there were other body parts that had not been found.

People along the river gathered together and talked about it.

Chen Yang, Liang Gang, Owen, Li Jianwei, Chen Haodang and others stood by the river. Team leader Liang Gang took a pack of cigarettes, tore open the package, spread it around, and said: "Since the water of the Maxi River was introduced into Jiangzhou City, the water volume has increased and the flow rate has obviously increased. The body parts should come from Dongcheng, or even farther away."

"Keep looking for body parts. This is the most important thing." Chen Yang stood by the river, smoking hard.

Owen walked up to Chen Yang and said, "Captain, the Serious Case Unit has no cases on hand, so leave this case to us."

Chen Yang glanced at the white hair on the young investigator's temples and said, "Every time a big case happens, you take the initiative to volunteer. That's great."

Owen heard the hidden meaning and asked, "Aren't you going to hand this case over to Group 1?"

Chen Yang said: "Let's talk about it later. I'm going back and reporting to the palace bureau."

After listening to the case report, Gong Jianmin, the deputy director in charge of the command center of the Municipal Public Security Bureau, said: "After the Huang Dasen bombing, we can no longer use the human wave tactic. Everyone is very tired. From now on, we will focus on Group 2 and continue the pursuit. Teng Mazi and Group 3 will withdraw and let Group 3 handle the dismemberment case."

Chen Yang said: "Team Three is handling the dismemberment case, so the revenge murder case will have to be put aside."

Gong Jianmin said: "After Group 3 participated in the pursuit of Huang Dasen, the revenge murder case was actually put aside. Serious Case Group 1, Group 2 and Group 3 are a whole, but there should still be competition between them, and they cannot eat from the same pot. It is a good thing to be unwilling to admit defeat to each other, and it is a manifestation of self-esteem. Owen led the Serious Case Group to solve difficult cases repeatedly. In comparison, Group 3 had the most difficult period. As an old investigator, Li Ming's self-esteem was hurt. This dismemberment case will be handed over to Li Ming. If the dismemberment case can be successfully investigated, Group 3 will be able to get out of the shadow left by the revenge murder case."

Chen Yang hesitated for a moment and said, "There are few clues in this dismemberment case, and it is quite difficult. If Team 3 stumbles again in this case, their morale will be ruined."

Gong Jianmin frowned and said, "Are you more confident in group one?"

Chen Yang thought about it seriously and said, "Maybe, but not entirely. Owen has been doing well since he started working and has not suffered any major setbacks. He has built up enough confidence. It would be a good thing for Owen to lead the team to investigate the dismemberment case and solve the case. If he fails to solve the case, morale will not be affected too much."

Gong Jianmin said: "The three teams of the Serious Crime Squad are not flowers in a greenhouse and do not need our protection. Every investigator has unsolved cases. If they lose confidence because they have not solved a case, they are too fragile and it is really not worth staying in the Criminal Police Detachment."

Chen Yang said: "Then I will talk to Li Ming. After the dismemberment case is handed over to Team 3, he must be fully alert and make sure to catch it."

Gong Jianmin then changed the subject and stopped talking about the case. He said, "I received a call from Lao Pu. The Provincial Public Security Department has officially set up a special task force for the Shannan Provincial Public Security Department's homicide backlog. Liu is the team leader. The task force consists of seven teams, of which Owen is the designated team leader of the second team. Five of the seven team leaders are from the team, and two are transferred from the municipal bureau."

Chen Yang was surprised and said, "Owen is going to be transferred? I haven't heard any news about it!"

Gong Jianmin said: "It took more than half a year to prepare for this plan before the department officially approved it."

Chen Yang said: "I originally wanted to recommend Owen as the deputy captain of the serious crime team, but I didn't expect the provincial department to be so accurate and ruthless. Entering the provincial department means reaching a new level. Although I am reluctant to let Owen go, I still support him. He is very proactive in his work. When he saw the body parts by the river, he took the initiative to measure the speed of the Jiangzhou River."

At this time, at the entrance of the Mabei Mountain Tunnel of Jiangzhou River, Owen, Lao Ke's team and two engineers from the Water Conservancy Bureau stood by the river. A fat engineer from the Water Conservancy Bureau said: "The flow rate of Jiangzhou River has two obvious sections. The flow rate is slow in the upper reaches. After passing Mabei Mountain, the flow rate is significantly faster due to the influence of the Maxi River. The flow rate is different in each season, with high flow rate in summer and low flow rate in winter. In addition, the water volume is large in summer, so floating objects will not be stranded and will drift farther with the current."

Owen asked: "What is the current flow rate?"

The fat engineer said, "That still needs to be measured. The easiest way to measure the flow rate on this kind of river is to use a buoy. Select two points on the river bank, put the buoy into the river, measure the time it takes for the buoy to drift from point A to point B, and then measure the distance between points A and B to find the flow rate."

The black bag containing the body parts floated down from the upstream, and by finding out the flow speed, we can roughly infer the time and place where the body was dumped. With the help of engineers from the Water Conservancy Bureau, they measured the flow speed below the Mabeishan Tunnel to be 2.1 meters per second, and the flow speed above the Mabeishan Tunnel to be 1.2 meters per second.

There are 8.2 kilometers from the Mabeishan Tunnel to the place where the black bag was found. The Jiangzhou River flows at a speed of 2.1 meters per second. It takes about an hour to flow from the Mabeishan Tunnel to the place where the black bag was found. Going upstream along the Mabeishan Tunnel, it is about 3 kilometers to the outskirts of the city. The flow speed in this section is 1.2 meters per second. It takes about 40 minutes to flow from the eastern edge of the city to the Mabeishan Tunnel.

That is to say, if the black bag is thrown into the river from the eastern edge of the city, it will take about a hundred minutes to reach the place where the black bag was found. The black bag was found at seven in the morning, which means that the bag needs to be thrown at the eastern edge of the city at around five in the morning.

The time of dumping the body varies depending on the location. The further east you go, the longer it takes and the earlier the body is dumped; the further west you go, the shorter it takes and the later the body is dumped.
