Chapter 1315 Robbery?

Chapter 1315 Robbery?

The group of people, each with their own tasks, quickly emptied most of the office.

The Jiangyuan backlog case task force and Cao Chujun's three detachments together have about 60 people, but when they are chasing several targets at once, the manpower is just enough.

Of course, this is the configuration for the homicide case project, and it was already like this in the early stages. If needed later, it would be natural to increase the configuration.

Liu Jinghui stood up, straightened his police uniform, and asked Jiang Yuan, "Want to come along and take a look?"

"Which part do you want to investigate?" Jiang Yuan asked, standing up as he spoke.

As the master of deduction, Liu Jinghui spends most of his time in his office reading documents and handling cases, and he doesn't even conduct as many crime scene investigations as Jiang Yuan.

Liu Jinghui was very satisfied with the dragon's obedience. He then spoke in a mature middle-aged tone, "I want to see if there are any signs of a struggle at the scene. Hmm... Although I said to start with the easy and then move on to the difficult, based on the current investigation, the probability of a robbery-like crime of passion is increasing."

“Yes, then let’s go take another look.” Jiang Yuan said “another.”

Liu Jinghui suddenly realized: "You've already checked the location where she fell into the water?"

"I didn't look carefully. I only glanced at the riverbank when I was collecting the diatoms. I walked along the river, but I didn't see any messy footprints near the edge. However, now that we've determined where the water fell in, it's a good idea to check the entire surrounding area." Jiang Yuan also realized this and felt that Liu Jinghui's idea was good.

He said the diatoms were collected along the Taihe River, but in reality, they were also collected from other sites along the river, roughly every 50 meters, for about 8 kilometers.

Jiang Yuan himself walked along the river, but not the whole way, mainly just glancing around. He mainly looked for signs of a fight on the riverbank, along the road, and in the surrounding green areas.

Because many of these places have paved roads, the grass doesn't leave footprints, and traditional methods of taking footprints like electrostatic discharge are not used, only particularly large anomalies would attract Jiang Yuan's attention. Even for Jiang Yuan, such observations could only reveal very obvious traces, and could certainly not be described as detailed.

However, according to Liu Jinghui's previous idea, now that the point of entry into the water has been determined, it would obviously be meaningful to thoroughly re-examine the area around the point of entry into the water.

Even if the deceased committed suicide by drowning, he might still have left traces of his passing.

If a robbery or similar incident occurred and the deceased had obvious injuries, then the two parties may have argued or fought near the point where the victim fell into the water, which could leave behind things like messy footprints or fallen plants.

Although the probability is not very high—mainly because there are cleaners and landscaping maintenance workers nearby who clean daily…

Thinking of this, Jiang Yuan immediately reminded him, "Find out to the sanitation department or someone to ask if there has been any repair work done on the green belts near the spot where the water fell in these past few days."

“I’ll call them,” Wang Chuanxing immediately accepted the task.

Jiang Yuan and Liu Jinghui then took a car to the location where the deceased had fallen into the water.

The Level 6 drowning-related plankton detection allowed Jiang Yuan to pinpoint the victim's fall location in just one day. Since samples were taken every 100 meters, the fall location was essentially within a 200-meter radius.

Running two 100-meter dashes can take as little as 20 seconds as Usain Bolt, but walking normally would take about 5 minutes. However, if you want to carefully survey the area, it would take about half an hour to complete the entire walk.

This riverside road near Changyang Vocational School of Science and Technology, from near to far from the Taihe River, consists of a stone riverbank about two meters wide, a green belt of two to three meters wide, a pedestrian walkway about two meters wide, a two-lane asphalt road, then another pedestrian walkway and a large green belt seven or eight meters wide. Further outwards, there are scattered buildings, open spaces, and small hills.

Near the point where the water fell, there is a restaurant, a teahouse, and a small park, all of which are far from the point. The restaurant also has its own greenery in front of it. There is no public transportation nearby, so diners either live nearby or drive by car. Most of them look out at the Taihe River dozens of meters away from the private rooms upstairs. If they want to see the riverside, they have to go out and cross the road.

In general, this riverside route is just an extension of the southern suburbs of Changyang. The main people who come here are students from nearby schools and residents of two small communities.

Police officers have begun interviewing people in the vicinity and collecting surveillance video, but so far they have not found anything.

Liu Jinghui brought Jiang Yuan over hoping that Jiang Yuan could find traces of the crime near the point where the drowning occurred, without even expecting to find any traces of the suspect.

Sanitation workers were cleaning along the riverbank, but after so many days, even if Jiang Yuan checked in person, Liu Jinghui didn't have much hope of finding any trace of the suspect.

Jiang Yuan had previously mainly walked along the river embankment, and this time he also walked along the 200-meter section of the embankment again.

Sanitation workers rarely clean the riverbanks, at least not daily or every other day. Theoretically, the stone riverbanks could provide some clues.

For example, if the footprints of the deceased Zhang Xianyao could be found, it would be very helpful in determining his condition on that day.

In reality, it's almost impossible to find them. During the day, the footprints on the stone embankment are barely visible, and at night, even with a surveying light, you only get a large number of messy footprints. Analyzing them one by one... is actually not very meaningful.

Several days later, the wind and humidity on the riverbank were high, and the green belt next to it provided a constant source of decomposers, which made the erosion of the footprints very fast and the deformation very severe.

Even for Jiang Yuan, it would be difficult to scan all the footprints of this type over a 200-meter stretch; at the very least, it would be very difficult to do meaningfully.

The most promising place is actually the green belt. Jiang Yuan hopes to find bent branches, deep footprints, etc. - if there was a conflict or fight at the time and it affected the green belt, this is the most likely scenario.

Half an hour later, Jiang Yuan could only spread his hands to Liu Jinghui.

"Nothing?" Liu Jinghui couldn't say he was disappointed; he could only say he saw no hope.

"We can't find any matching traces. What did the sanitation department say?" Jiang Yuan asked.

"No. I asked the sanitation workers who cleaned this section, and they didn't find anything unusual either." Liu Jinghui frowned, looked behind him again, and said, "We didn't find anything either among the customers with records of purchases at the restaurant or the staff."

"Okay, fine." Jiang Yuan was used to not getting any results. In the process of handling cases, what he encountered most often was actually not getting any results.

Liu Jinghui could only shake his head: "If it's not a robbery or a conflict, this case will be difficult to handle..."

"Look ahead," Jiang Yuan suddenly pointed ahead and said, "The point of impact is over here, but it doesn't necessarily mean it happened right here."
