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

After Tang Jun came out of the rental house, he did not choose the nearest route back to the hotel.

"I came here during the day and checked. The surveillance cameras were good. I deliberately avoided them because I still had to go to the pond. I had already thought about throwing away my shoes and other things by the pond. There was also a piece of clothing. The clothing was stained with blood, but I was afraid that it would float in the pond, so I didn't throw it in the pond."

He handled the relevant murder weapons and the clothes and shoes that Tang Jun was wearing at the time in batches.

When he reached the edge of the pond, he pointed to the spot where he had thrown his shoes.

"The fruit knife was buried under the wall of the self-built house over there, but I forgot which one it was, anyway, it was under the wall near the cafeteria."

There are no self-built houses within thirty meters around the pond, so the distance is still quite far.

Following the direction pointed out by Tang Jun, the police took Tang Jun there and soon found traces of turned soil under the wall of one of the self-built houses.

The other party was not buried very deep. They should have used the tiles nearby to dig a small hole, and soon found the fruit knife that killed Zhang Lili.

"Director Lu, this is it."

The following scene shows the fruit knife being brought to Lu Chuan. The blood stains on it have been cleaned off, leaving only some brown marks.

"Take it back for experiments, extract fingerprints, and compare blood types."

"Yes!"

It doesn't mean that just because Tang Jun identified the fruit knife sold in this place as the murder weapon, it means that it is definitely the murder weapon.

But the evidence is about details, so the bloodstains on the fruit knife must be analyzed to see if it belongs to Wang Mengmeng, and whether the fingerprints on it can match Tang Jun's fingerprints. These are all very important.

The detection of murder weapons is the most important part of any criminal case.

A dozen or twenty years ago, technology was not as advanced as it is today, and the criminal investigation process in some places was not so rigorous, so many cases were missed.

Lu Chuan studied a case when he was in college.

The suspect's confession was also about a murder with a sharp knife. The results were basically consistent with the crime scene investigation, but the problem was discovered after the murder weapon was found.

Because the suspect burned the body after killing the person, some results are uncertain.

After finding the knife, the police did not conduct a detailed inspection of the remaining materials on the knife.

Many years later, when another missing case was solved, it was discovered that although the murderer had killed someone, the person he killed was not the person the police believed to be dead at the time.

The blood stains left on the sharp knife were actually pig blood, not human blood at all. The whole process was a conspiracy and a frame-up.

Therefore, all the people involved in the case at that time were dealt with, and the key thing is that the case was not solved at that time, and the suspect had already escaped the law and went abroad.

After so many years, the case has not been completely solved.

Every step in the criminal case investigation process is essential and this is a hard rule. Lu Chuan is always very cautious when executing these procedures.

Another is the necessity of identifying the scene.

Identifying the scene is not like taking photos in movies, or pointing randomly like watching news footage of a suspect. That's it. This is not identifying the scene, this is called posing.

In fact, the identification of the crime scene requires the suspect to reconstruct the entire crime process at the scene, including when and where the conflict occurred and what actions were taken during the conflict. The suspect is required to repeat it as clearly as possible.

This is to prevent the suspect from committing a crime on someone else's behalf.

It's not like there haven't been such cases before.

Three years ago, a similar case happened in Haizhou City. The son killed someone and the father came out to convict him.

The result was that when identifying the crime scene, the father did not describe the entire process of the murder very clearly, and some of the details were even completely opposite to the police's investigation results and were full of contradictions.

It was precisely because of this that it was finally determined that this was a case of taking the blame.

After finding his brothers, Chen Jiang, Lu Chuan and others continued to escort Tang Jun to the small hotel where he had lived. Tang Jun demonstrated the entire process of climbing in from the kitchen window on the first floor and then returning to his room.

"I didn't have time to wash the clothes I wore that night. They are in the suitcase under the bed. You can see them once you open it."

In fact, Tang Jun originally wanted to burn or throw away the clothes, but felt it was a pity.

The coat and shirt were both bought this year, and the pants were also a new pair bought not long ago last year, so he thought of washing them and wearing them later.

But before he had time to clean it, the police kept coming to his door to ask about the situation, and he dared not take any action.

In this way, the whole case was completely solved.

The Criminal Police Brigade was responsible for sorting out the relevant materials and the entire case. That morning, Lu Chuan took Wang Zhaokai to report to Chen Weiguo of the High-tech Zone Branch.

In the afternoon, Chen Weiguo and Lu Chuan went directly to the Municipal Bureau and reported the relevant situation to the Municipal Bureau Director Song Jiangguo.

The impact of this case is quite large. Two people died, and the disease spread very quickly in densely populated areas.

But fortunately, Lu Chuan and others solved the case quickly.

Within three days, the Tang army was captured.

This is the Criminal Police Brigade.

The relieved crowd gathered together to discuss the case.

Sun Biao picked up the teacup and took a sip.

“I feel like this case is a bit ridiculous.”

"There are actually two reasons why Tang Jun killed someone. First, he must have had a grudge against Wang Mengmeng and Zhang Lili. He and Liu Lingling had almost agreed to remarry, but after these two girlfriends instigated the matter, the plan basically fell through."

"The second one was the passionate murder that night."

Chen Jiang was responsible for the entire interrogation process, and he agreed with Sun Biao's judgment.

"In fact, the two of them didn't have any deep feelings for each other. After Liu Lingling divorced, she felt that it was okay to remarry or not, but her family didn't agree with her remarriage, and her two best friends didn't agree with her remarriage either."

The reason was very simple. Both Liu Lingling's family and her best friend believed that he had no children, and Liu Lingling could get some dowry money if she got married again.

In particular, Liu Lingling's family strongly opposed his remarriage and have recently been thinking about arranging a blind date for her.

"The divorce was because Liu Lingling's grandfather lost 1000 yuan, and Tang Jun took it, so the conflict was over there."

"It's too utilitarian. They just treat marriage as a transaction and don't even think about spending their whole life together."

But the police can't do anything about this kind of thing.

It is still very common in rural areas. (End of this chapter)
