Chapter 2432 Solve the mystery!

Zhen Zhen felt that Wu Jia must be Zhang Shanshan, so he immediately arranged for people to keep an eye on Zhang Shanshan. At the same time, he also arranged for people to search the places where Zhang Sicheng had stayed before his death to see if there was any data that could be used to check DNA.

She wanted to check whether the DNA that Bai Xiaofu was investigating before her death was the same as Zhang Sicheng's.

After all, if it was really Zhang Sicheng who killed Bai Xiaofu, it must be that Bai Xiaofu threatened Zhang Sicheng.

But Bai Xiaofu is Zhang Sicheng's wife, and they have a child. Under what circumstances would Zhang Sicheng have to kill Bai Xiaofu?
Zhen Zhen soon found out that before Bai Xiaofu died, she seemed to have been commissioned by Lao Lu from the Evidence Examination Department to check the DNA left under the fingernails of a deceased person.

Zhen Zhen felt that this DNA was the key clue to the matter.

Captain Lu actually knew about the investigation arranged by Zhen Zhen, but he felt that using big data to investigate cases was a bit ridiculous. However, Zhen Zhen was his direct superior, and even Director Lin Hao supported her, so he could only reluctantly agree to Zhen Zhen's investigation.

Therefore, Captain Lu never took Zhen Zhen's investigation seriously. She felt that Zhen Zhen, a big name in the criminal investigation field, must be from the academic school, with too much theoretical data and a serious lack of experience.

Even Captain Lu began to doubt the cases that Zhen Zhen had handled in the past.

However, the slap in the face happened soon. After the progress of Zhen Zhen came out, Captain Lu had to take it seriously.

After all, Zhen Zhen used big data to actually find the very suspicious murderer.

When a criminal policeman who has been in the profession for more than ten years pays attention to a person, many details of his life can be infinitely magnified.

For example, when they were solving the case in 1997, they always felt that someone seemed to know them very well.

Now that I think about it, Captain Lu’s master Wei Zhengrong and Bai Xiaofu were originally a couple. Although they broke up later, they had always been in contact and their relationship was extremely ambiguous.

Even Bai Xiaofu's son's name is Zhang Shanshan, which is exactly half of Zhengrong's. This stimulates Zhang Sicheng all the time.

It is very possible that a person will gradually become a pervert under such circumstances!

Captain Lu thought of the provocative message Wei Zhengrong received that year, "His honey is my poison. You can't take it away, but I will get it in the end!"

And it was not long after this news came out that Bai Xiaofu died. What a coincidence!

Now Zhen Zhen's investigation results have made Captain Lu suspect that when Bai Xiaofu had a car accident, it was very likely that Zhang Sicheng was chasing Bai Xiaofu.

Therefore, even if Zhang Sicheng is not the murderer of the serial killers, he is the murderer of Moran.

So, Lu Xingzhi told Wei Zhengrong the news and asked Wei Zhengrong to investigate it personally.

Then, a sad fact was laid before everyone!

The murderer thirteen years ago, Zhang Sicheng, is dead!

And the one killing people now is Zhang Sicheng’s son, Zhang Shanshan!

What kind of situation led to Zhang Shanshan inheriting his father's business?
Wei Zhengrong, Zhen Zhen, Lu Xingzhi and others were all feeling very aggrieved, so they wanted to catch Zhang Shanshan red-handed and interrogate him thoroughly!

……

It was during this multiple investigation that Zhang Shanshan, who knew nothing about it, was caught by Lu Xingzhi who rushed out when he kidnapped Xue Hong and was about to kill her to make a picture.

Even when he was caught red-handed, Zhang Shanshan remained silent at first. When he heard that Wei Zhengrong was the one who arrested him, he asked Wei Zhengrong to interrogate him, and then he told the truth.

It turned out that Zhang Sicheng had been torturing Zhang Shanshan for years after Bai Xiaofu's death, and before he died, he told the truth about his murder.

It was all because Wei Zhengrong was a policeman and Zhang Sicheng happened to have killed Mo Lan, so he deliberately provoked Wei Zhengrong, his love rival.

After hearing this result, Wei Zhengrong looked much older in an instant, and the others also fell silent.

In fact, Wei Zhengrong is also a pitiful man. He and Bai Xiaofu were in love with each other. But when he was on a mission, he was infected with a virus and thought he was going to die, so he broke up with Bai Xiaofu.

What Wei Zhengrong didn't expect was that he unexpectedly survived, so he couldn't wait to find Bai Xiaofu.

But at this time, Bai Xiaofu was so angry that she married Zhang Sicheng, and the two missed each other.

It’s hard to say who is right or wrong. We can only say that it’s fate that plays tricks on us.

...When Zhen Zhen and Wang Yue described the process of solving the case, they said with great emotion, "After the establishment of the anti-crime cooperation organization, this old case was suddenly solved. It really boosted the morale of the domestic police."

Wang Yue had to admit that this was indeed true. The fact that such an old case could be solved really showed the strength of the domestic police. If the news of this case being solved spread, the police officers involved in the case would be able to hold their heads high.

Wang Yue saw Zhen Zhen was obviously proud of this case, and suddenly realized something, so he asked very seriously, "Should we announce it to the public?"

After listening to this, Zhen Zhen nodded and said, "I heard that they are preparing to announce the optimization of the border inspection process, and our anti-crime cooperation organization also needs to expand its team to ensure that domestic security is not affected after the entry procedures are optimized.

But after hearing about our plan, the LW region also wanted to participate, and recently we are considering whether we should wait for them. "

Wang Yue knew that this would not be easy to accomplish, so he jokingly said, "By the way, Zhen Zhen, you are using big data to investigate cases. I'm afraid this will open up a new faction in the police force."

Seeing that Wang Yue had changed the subject, Zhen Zhen did not continue. Instead, she said proudly, "They didn't expect that it would be so easy to find the murderer by investigating in this way, so they planned to use this method more often.

It's just that they don't have the same technology as you, and they can't quickly and accurately check and compare from the database."

Wang Yue saw the look in Zhen Zhen's eyes when she said this, and he immediately understood what Zhen Zhen wanted. He took out a USB drive and said helplessly, "You can use the automatic screening auxiliary system. I wonder if they can trust my software except you?"

Zhen Zhen took the USB drive and kissed Wang Yue on the face, then said simply, "Never mind them, I'll take this thing over anyway, do I need to look at them?
However, I think it will probably be used, but it may be mirrored to prevent accidental leaks. "

Wang Yue thought this might be the case, so he let Zhen Zhen hand it over without any worries. He thought it would most likely be used in Yunnan and Nawa areas at the same time, and would consider whether to promote it after a period of trial.

In fact, it was just as Wang Yue imagined. After Zhen Zhen handed over the software, some people really had concerns, but they were reluctant to not use such a good thing.

Therefore, the Yunnan police mobilized a large number of manpower to develop their own software while also preparing to use it in Yunnan and Nawa areas.

If it is used appropriately, it will be gradually promoted in border areas in the future, and of course it will be used together with other areas of the border.

If it is used inappropriately, it will be terminated directly and the loss will not be particularly large.

When Wang Yue learned about this result, it was before the announcement of the joint anti-crime regulations, which could be regarded as a message to Wang Yue first.

Wang Yue was not mentally prepared for this result, so he did not raise any opinions. If they took joint action, Zhen Zhen would be able to meet him more often, which made him even happier.

After all, Wang Yue has not seen anyone more suitable than Zhen Zhen to continue to preside over this cooperative organization. In the future, Zhen Zhen will not have to travel between Jinshanjiao and Yunnan, and can just stay in the Nawa area.

……

After the incident of optimizing entry procedures in Nawa region and Yunnan was announced, it was more shocking than the anti-crime cooperation organization and immediately attracted the attention of the whole world.

In particular, several neighboring countries, especially the armed forces in the NM region, are all worried.

It’s just that now it’s not the two major regions that have simplified the entry procedures, but only the two small regions that have simplified the entry and exit procedures, which makes people a little confused.

Unlike other countries that were hesitant, the LW region was the first to respond.

They knew that it was not easy to apply for the entire region to join this simplified process, so they let their six northern provinces form the northern Laos region and apply to join this project to simplify entry and exit procedures.

The LW region was already troubled by the frequent appearance of criminal organizations on the border, but now, after a joint crackdown on crime, their public security has improved a lot, so they think it is better to apply to join the simplified entry procedures, which will be beneficial to the development of the tourism industry.

As the main members, Nawa and Yunnan, after brief consultations, the two sides decisively agreed to the joining of the northern Laos region.

The TG region has always attached great importance to tourism, and they feel that if the entry process is simplified, it will also be a good boost to their income.

Therefore, after the northern Laos region joined, the Lanna area in the TG region also applied to join in order to attract domestic tourists to travel.

The entire Lanna area is actually the nine northwestern provinces of the TG region. Due to the influence of the border environment, the tourism industry in these areas is relatively poor, which has always been a headache for the TG region.

The Mekong River was rectified some time ago and so many criminals were cracked down on, which has improved the public security in their country and increased the number of tourists.

This also gave the TG region more recognition for the anti-crime cooperative organization.

People from all over the country feel that, if public security permits, simplifying the entry and exit procedures will not only promote the development of tourism, but also allow people to go abroad and prosper the local economy, so they are all very excited.

However, this caused headaches for other countries.
