"Team Qiu's analysis just now is very accurate. Let me add a few more points."

Li Xiang is not modest. People already look down on you. If you continue to hide your humility, others will look down on you even more.

So he immediately got into the situation, assumed the position of leader of the task force, and began to conduct a comprehensive analysis of the case.

He did not elaborate on the content of Qiu Cang's previous analysis, but directly added: "As for the source of the corpse, I would like to share a few opinions. First: the body parts in the plastic bag are only some of the stumps and broken arms of the victim. So, Where are the remaining parts, especially the most important head. Since the murderer chose to dump the body, it is impossible to dump only part of it. We have to find where else is there first. If we find it, this case will be half solved."

"Of course we know that there are still some human tissues that have not been found. The key question now is that we have searched everywhere, not only in the river, but also on the shore, within a five-kilometer radius of the center point, and still can't find it. "

At this time, a young detective sitting in the audience spoke.

Huali Huawei is also saying that what Li wants to say is nonsense. If experts are all of this level, then he can also be an expert.

"Xiao Mo, wait until Team Leader Li has finished speaking." Seeing Xiao Mo in the team suddenly attacking Li Xiang, Qiu Cang's expression changed. What he was most worried about had happened.

If Li Xiang gets upset and goes back to sue them, they will be in trouble.

Even though Li Xiang is young, he can bully him.

The younger he is, the more it means that the other person has an unusual background.

Maybe the young master from whose family came out to practice.

Otherwise, he could be sent out at a young age?

He thinks he has a relatively clear view on this matter, but he is afraid that the people under his command will not accept this trick and will contradict the other party and then be put in the shoes.

Xiao Mo was still a little afraid of Qiu Cang. When the captain spoke, he swallowed it even though he was angry.

He turned his head and stopped talking.

Li Xiang did not argue with him and continued: "Second: the investigation of missing persons. I see that you visited and investigated very carefully, including migrant workers. It is very good, but we cannot limit it to the local area and surrounding cities. We must also investigate and do not rule out the possibility that the murderer dumped the body across the city. I request that all the police records of missing persons in the surrounding area in the past three months be carefully screened, as long as they are looking for someone, even if they are not close relatives."

"Okay, we are still investigating the missing persons, because we cannot yet determine the physical characteristics of the deceased. Now we can only roughly screen based on age, and then compare the blood stains of the family members for DNA testing to rule out the possibility, so the progress is relatively slow. ." At this time, Qiu Cang explained that in fact, they have been carrying out the content arranged by Li Xiang.

"Okay then. Finally, let me talk about the analysis of the suspect. Judging from the body parts picked out from the garbage bag, it is the murderer's first time to kill. The dismemberment method is very immature, chopping the bones like avoiding ribs. Human bones are very hard, and friends who often dismember bodies should know that the knife should be cut at the bone joints to dismember the body, which saves effort and is less likely to dull the knife."

Frequent dismemberment?

Everyone in the task force broke out in a cold sweat. This expert looked young, but he was also a ruthless person.

"Of course, this is off topic. It can be seen from this that the murderer should be the first time to kill someone. So let me ask you another question. Have you ever thought about why the murderer chose to dismember the body?"

Facing the questions raised by Li Xiang, the elite detectives who had just been restrained by Li Xiang soon had different answers:

"The murderer may be trying to hide something."

"Maybe it's some kind of hobby."

"Easy to transport?"

Everyone has different opinions on murder and dismemberment, and everyone has expressed his or her own opinion.

"You are all right, but combined with this case, I think it is more likely to be convenient for transportation. The murderer probably did not have a car or bought a suitcase, but chose the most economical garbage bag. This shows that the murderer's economic The strength should not be strong. Secondly, you have basically completed the investigation of the local missing persons. The next step is to investigate other places. I think we should investigate along the upper reaches of the Xiangshui River."

"Bring the map."

Soon, the local map was spread out. Qiu Cang marked the location of Xiangshui River on the map, and put a five-pointed star on the location where the body was found.

"This is where the body parts were found."

"I need data on the water flow and water depth of the Xiangshui River during this period. Please arrange for someone to measure it."

Li Xiang also suspected that the body parts were caused by the recent overgrowth of water and grass, and then the rainwater level rose and flowed downstream with the water. Now he had to judge the approximate location of the body based on the speed of the water flow and the degree of decay of the body.

"Okay, I'll contact you now."

"It just so happens that I have nothing more to say, so I will go with you to the crime scene and take a look at it, bringing the map with me."

Qiu Cang immediately contacted the technical department, brought professional measuring tools, applied for a kayak, and set off.

Four police cars formed a convoy. The last pickup truck had a kayak on it and some professional measuring tools on it, and drove all the way to the scene of the crime.

Yang Ming, who was driving, saw that Li Xiang was calm and composed, so he asked curiously: "Captain Li, do you have any idea?"

"I have some ideas, but we have to wait until the measurement results come out before we can be sure."

After Li Xiang came, he found that this case was not simple.

Even more difficult than the 3 mystery he solved last time.

Because the police had fewer clues this time, he couldn't even perform skull reconstruction because there was no skull.

There's just a pile of minced meat, how can I check it?
There is no way to check it, even if it is turned on.

He is not a god, nor is he a judge of the underworld. He can tell who she is, how she died, who killed her, and whether she has any grievances by looking at the book of life and death.

He is not.

All cases must be solved based on evidence. Without evidence, there is nothing he can do.

Long Hai's task force is not a fool. They investigated for a week and sorted out all the clues they could find. They still had no clues. They could only ask the provincial department for help, hoping that some experts would come and give some ideas.

So Li Xiang came.

The vehicle stopped soon. Li wanted to get out of the car and saw Qiu Cang walking over.

"Team Leader Li, let me take you to see where the body parts are recovered first."

"it is good."

Qiu Cang brought Li Xiang to a cement embankment. Looking around, he saw that this was a winding waterway, only a hundred meters wide. The water was turbid and overgrown with aquatic plants. A large part of the aquatic plants on the embankment had been salvaged. Under the sunshine, Under the irradiation, it has shriveled.

Looking back, I saw a cement road next to the embankment. It was well built and there were many pedestrians coming and going.

Seeing a police car parked here, they all got out of their cars and started to watch.

The nearby villagers already knew that a murder had occurred here. When they saw several police cars coming with boats, they also ran over curiously to see the excitement.While driving away the spectators, members of the task force cooperated with technicians to put the kayak into the water, and then threw some measuring instruments such as buoys and neutral floats into the water.

This is the buoy drift flow measurement method, which determines the flow rate and direction of river water based on the flow of free drifting objects with the river water. It is mainly suitable for surface flow observation of river water.

Through the flow measurement data, the time of death estimated by the forensic doctor, and then based on relevant formulas, Li Xiang was able to estimate the approximate location of the body parts.

In order to accurately measure the time, the buoy measured for half an hour, and then the on-site technician summarized the data in the computer and gave it to Li Xiang.

Li wanted to know the formula, but it was too laborious to calculate.

He has his own labor-saving method. In order to control the "Xiaomu" at home at any time, Li Xiang bought a laptop, which can remotely control the workstation at home.

This allows him to get the computing power support of "Xiaomu" anytime and anywhere.

Li Xiang gave the measured data to "Xiaomu", and then asked it to estimate how far the body parts traveled in the water based on the time of death estimated by the forensic doctor.

While waiting, Li Xiang had already seen the direction of the water flow, and then asked Qiucang to bring the map over.

"The direction of the water flow is from northwest to south. In other words, the body parts are most likely from the northwest, which is where this area is."

Li Xiang drew a circle on the map. Any area where the Xiangshui River flows may be the place where the body parts were dumped.

"This Xiangshui River flows through three cities, namely Langhua, Huaicheng and Yuquan. Once I calculate the floating corpses, I can roughly calculate the first place where the corpses were dumped."

After hearing what Li Xiang said, Qiu Cang finally recognized Li Xiang's status as an expert.

Although they also have buoys and other equipment that can measure the speed and direction of water flow, their initial investigation direction was mainly local and they spent a lot of time visiting and investigating.

It was also before Li Xiang came that he focused his investigation on surrounding cities.

However, measuring the body dump site through water flow is not a simple matter. It is easy to say that the measurement is accurate. If the measurement is inaccurate, the entire investigation direction will be biased.

So even if Qiu Cang knows this method, he doesn't have the courage to use it. He would rather spend more time and investigate one more city than go all the way to death and lead everyone into a ditch.

Only the expert group came over and said that this method should be used. If something went wrong, Li Xiang would take responsibility.

So when Li wanted to come over, the first thing he thought of was the buoy drift current measurement method. He was also quite surprised. This courage alone deserves recognition.

"Ding."

The computer beeped and "Xiaomu" had been calculated. Li wanted to take a look and calculated based on the formula that the body parts had drifted in the river for about fifteen kilometers. If the water level rose due to the last rain and the body parts were washed away, If you come here, the distance will be shortened to about five kilometers.

In other words, the location from five kilometers to the northwest to fifteen kilometers from the place where the body parts were salvaged is the first place where the body was dumped.

Seeing this result, Li Xiang asked them to bring a ruler to measure and map on the map.

"This ten-kilometer stretch spans two cities and is right at the junction of Huaicheng and Yuquan."

After Li Xiang's surveying and mapping, the ten-kilometer stretch of river in the middle happened to be at the junction of the two cities.

"It's not a loss. At least one city has been reduced and the workload has been reduced by one-third."

Seeing this result, Qiu Cang comforted him.

“One more city can be ruled out.”

At this time, Qiu Cang suddenly heard Li Xiang's affirmative tone, saying that one more city could be reduced, and asked curiously: "How to investigate?"

"Have you forgotten what I just said? Why did the murderer choose to dismember his body?"

"Easy transportation, don't have a car?"

"Yes, this is the suspect's first murder, and his psychological quality is definitely not strong. Panic is inevitable. In addition, he did not have a car to transport the body, nor did he use a suitcase to transport the body. Instead, he chose to throw the body in a garbage bag. Four pieces for a person, not one or two. If you use a garbage bag of this size, you must put at least four bags with four bags of body parts. He will definitely not choose to dump the body arrogantly. You see, it borders Huaicheng and Yuquan. Let’s analyze the location and characteristics of the Xiangshui River and see if you find anything?”

After hearing what Li Xiang said, Qiu Cang quickly looked at the map.

This look really gave him some clues.

The places where Huaicheng and Yuquan meet the Xiangshui River are on both sides of the river. Traffic is relatively developed on the Huaicheng side. There happens to be an expressway built on this section of the road. Generally, non-motorized vehicles cannot go there, so it is difficult to complete. Dumping corpses, but Yuquan is different. It just borders the edge of the city. There is a village here. The name of the village on the map is Xiaowang Village.

"If I were a murderer, I would probably choose this area."

"Not bad, I don't need to say anything about what to do next, right?"

"I understand."

Seeing that Li Xiang had narrowed the scope to a village, Qiu Cang, as the leader of the task force, naturally knew what to do next.

He immediately called the members of the task force together and assigned the tasks of each group.

The kayak was put away and after completing the measurement task, everyone called it a day and went back.

The next focus of investigation became Yuquan Xiaowang Village.

Li Xiang also followed the field investigation team and prepared to go to Xiaowang Village to take a look at the situation.

This place is only about ten kilometers away from Xiaowang Village, and they arrived there in 10 minutes by car.

"Along the Xiangshui River, all social surveillance and civil surveillance data within a five-kilometer radius are copied for as many hours as possible."

"Yes."

"The villagers in Xiaowang Village will also visit and investigate to see if any girls have lost contact recently. The men will also investigate in the same way."

Although the deceased was a woman and missing persons were mainly investigated for women, Qiucang had rich experience in handling cases and knew that men should also be included.

Often this decision may have unexpected gains.

Because Li wanted to say that the murderer is very likely to be a novice. If he is a novice, he will be nervous. What if the murderer is from Xiaowang Village and he absconds in fear of crime. Didn't he just hit the gun of the police?
"Yes."

Qiu Cang arranged their respective tasks in an orderly manner, and everyone carried them out quickly. Soon, only Li Xiang and the others were left on the scene.
