Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 1169 Behind the Suicide
In this case, if Lu Chuan and others just made this case a simple suicide, it would definitely not make sense. Judging from the clues we have obtained so far, the possibility of Wang Dahai committing suicide is very small.

Of course, judging from the scene where Wang Dahai jumped off the building, he must have jumped by himself.

The results of the on-site investigation came out last night, and the forensic report was also reported to Lu Chuan.

First, let's take a look at the criminal police's investigation into the house where Wang Zhaokai jumped from.

The first one is the traces found inside the house, which only belonged to Wang Dahai and Zhao Limei.

The criminal police have now carefully investigated the footprints, fingerprints and other conditions at the scene, and combined with the traces of life, the supplies in the kitchen, the clothes in the cupboards, the shoes in the hallway and so on, they can be confirmed that the people living in this house are Zhao Limei and Wang Dahai.

In addition, the on-site criminal police conducted a detailed investigation on the balcony where Wang Dahai jumped.

There are obvious traces of the lighthouse on the balcony and the windows of the balcony, and through identification and comparison of footprints, it can be confirmed that they belong to Wang Dahai himself.

Although Zhao Limei's footprints were collected on the balcony, they were very few, only a few, and the rest were all Wang Dahai's own. Two cigarette butts were also collected on the balcony.

The two cigarette butts were in a state of natural extinguishing, which means that after Wang Dahai finished smoking, he casually threw the two cigarette butts on the ground without crushing them.

The saliva on the cigarette butts was also extracted and DNA analysis results showed that the saliva on the two cigarette butts belonged to Wang Dahai himself.

The lighter and cigarettes on the balcony also had Wang Dahai's fingerprints on them.

The cigarette butts in the ashtray on the coffee table were also identified, and the results showed that they were all smoked by Wang Dahan himself, with no traces of any outsiders.

Then the on-site investigation police simulated the location and range of Wang Dahai's fall from the 13th floor, which was consistent with the situation of a natural fall.

The final conclusion given by the on-site investigation was that Wang Dahai was probably alone at home and then jumped off the balcony.

From the perspective of on-site investigation, the conclusion that Wang Dahai committed suicide is valid.

Lu Chuan was not at all surprised by the conclusion of the on-site investigating police.

As for the on-site investigation, Lu Chuan said that first, no one in the entire Haizhou City or the entire province dared to speak. Second, although he did not use instruments to carefully investigate the scene, he could basically determine it after walking around. Wang Dahai was indeed the only one at home at the time, and the other party did jump off the building and died.

The analysis data provided by the on-site investigating police only further confirmed Lu Chuan's conclusion from the evidence level.

In addition, the forensic examination of the body also confirmed that Wang Dahai did die from falling from a high place.

There were obvious signs of rupture and contusion of many organs in the body caused by falling from a high place.

The time and cause of death all correspond to what was found at the scene.

The reason why the time of death corresponds to the situation found at the scene is to prevent someone from killing Wang Dahai in advance and then pushing him down the stairs.

Another thing is that the cause of death is the same.

Lu Chuan had handled a case before. The victim was actually strangled to death by Le Jing before being pushed down the building to make it look like a death from a fall.

The murderer thought that this method was very safe and covert and no one would notice it. However, once the forensic doctor identified the cause of death, it would be easy to identify that it did not match the characteristics of a high fall, so it could not be hidden at all.

Now let's look at the fact that Wang Dahai committed suicide. It is certain, but why did Wang Dahai commit suicide? This is the reason behind it that the police need to find out.

Judging from the current investigation results, Wang Dahai holds a huge amount of wealth and such a person should not commit suicide.

What's more, he committed suicide by jumping off a building in his mistress's home, which is even more unreasonable.

"Looking at Zhao Kai's condition, the Criminal Police Brigade must focus on investigating the cause of Wang Da Kai's suicide. He did not leave a suicide note, but only left his ID card and cell phone on the coffee table."

After some thought, Lu Chuan began to arrange the next investigation direction and key tasks.

Wang Dahai did not leave a suicide note when he committed suicide, but there was one thing that was rather strange: he placed his ID card and cell phone on the coffee table, and they were arranged very neatly.

Generally speaking, most people don't carry their ID cards with them. They may be placed in a drawer at home or in a fixed location, such as together with their household registration booklet.

But before committing suicide, Wang Dahai took out his ID card, placed it on the coffee table in a bright yellow color, and placed it together with his mobile phone.

Given the degree of dependence of people on mobile phones in modern society, Wang Dahai apparently placed his mobile phone on the coffee table in the last moments of his life, and then smoked on the balcony before preparing to commit suicide.

This is a bit strange. Why did Wang Dahai do this?
"I think we should first check Wang Dahai's close contacts. The fact that he has so many properties is definitely related to his being the director of the grain depot. So we should check Wang Dahai's economic behavior before his death. There should be something wrong with it. Is his suicide related to this? I think we can make a similar hypothesis now."

This is what Lu Chuan thought of naturally.

Wang Dahai has so many properties. Regardless of where these things came from, they must be related to his work. This is basically certain.

So, Wang Dahai embezzled so much money. Was it just one person who did it? Were there other people above him or below him?

Where are the greater interests? Is his death related to the greater interests?

Lu Chuan felt that in order to find out why Wang Dahai committed suicide, he had to understand Wang Dahai's entire interpersonal relationships and interest relationships. Once all these relationships were sorted out, many things would naturally come to light.

Of course, it might not be enough for the Criminal Police Brigade alone to investigate this matter. After all, Wang Dahai is a civil servant. So after Lu Chuan made the arrangements, he went to the High-tech Zone Branch to call him, and Chen Weiguo went directly to the Municipal Bureau.

The criminal police mainly investigate criminal cases, such as economic crimes, which are generally handled by the Economic Investigation Detachment.

Therefore, for some matters, they still have more methods and richer experience over there. Lu Chuan meant to ask for instructions from their superiors first.

As for the High-tech Zone Branch, it doesn’t matter. It has its own professional department for economic crime investigation.

As the deputy director, Lu Chuan can be transferred.
