After returning to the office of the second group, Han Bin immediately called a meeting of everyone.

"Binzi, what did you do just now, there was no one in a blink of an eye. Li Hui said curiously.

"I went to Team Zheng's office, and in order to have a more in-depth understanding of the 715 case, Team Zheng invited the person in charge of the 715 case and told me about the investigation of the case. Han Bin said.

"The person in charge of the 715 case back then seems to be called Ding Xifeng. Tian Li remembered that the file had the signature of the person in charge.

"Not bad. Han Bin responded.

"How I feel, the name is somewhat familiar. Li Hui muttered.

"This senior Ding was the person in charge of a major case ten years ago, and now he is probably a leader. Zhao Ming guessed.

Han Bin didn't sell it, and introduced: "He is now the deputy captain of the Municipal Criminal Investigation Detachment and the captain of the First Municipal Criminal Investigation Brigade. ”

"My day, such a cow!" Zhao Ming said in surprise.

"I'll just say, I think I've heard it somewhere. Li Hui muttered.

Tian Li's heart was more careful, and she frowned: "Team Leader Han, what does this Captain Ding mean when he comes to our branch?"

"Provide clues and guide the investigation of the case. Han Bin said.

"Doesn't that mean that if we solve the case, we will have a share of Captain Ding's credit. Zhao Mingdao.

Han Bin smiled: "Don't worry, Captain Ding doesn't look down on our little credit, as long as you don't make mistakes." ”

Han Bin's words have two meanings, the first is not wrong, which means that there is no mistake in the investigation of the case, and the second is that Ding Xifeng has the idea of making amends.

Since Ding Xifeng is here, he must be named, so that even if Han Bin and others discover new clues and overturn the direction of the investigation of the case that year, it will be completed under the guidance of Ding Xifeng.

For this case, Ding Xifeng does not seek merit but no fault.

The person in charge of the case is Han Bin, this point must not be able to run, originally knew that it was Zheng Kaixuan who investigated the case, and now there is another Ding Xifeng, as long as Zheng Kaixuan has no opinion, it will have no impact on Han Bin, and it will not affect his credit.

With Han Bin's words, everyone has a bottom in their hearts.

The people present were not stupid, the people who handled the 715 case back then basically became leaders, and if the people in the second group didn't care about only thinking about making meritorious contributions and overturning the original direction of the investigation of the case, even if they solved the case and made meritorious contributions, they might have been recorded in a small book by a certain leader.

Now Ding Xifeng is willing to come out to carry the banner, but Han Bin can't ask for it.

After a brief introduction to the situation, the morale of the second group of members was also restored, and Han Bin began to arrange tasks.

"Li Hui, Xiaopeng, you two go to the communication company and check Lu Jiaping's call records to see if there are any abnormal contacts. Han Bin commanded.

"Yes. Li Hui smiled.

If Lu Jiawei is still alive, it is very likely to contact his sister, as long as he finds clues from the communication records, he can find out Lu Jiawei's location and arrest the other party.

"Zhao Ming and I went to Lu Jiaping's house again, made a transcript for her again, and extracted Lu Jiaping's DNA at the same time. ”

"Tian Li, you write a report and apply for a re-examination of the identity of the deceased, re-compare the DNA samples of Lu Xiaojie and the deceased, and at the same time, compare the DNA samples of Lu Jiaping and the deceased to see if there is a blood relationship between them. Han Bin said.

"Team leader, do you want to compare Liang Zhibo's father's DNA with the DNA of the deceased. Tian Li said.

"Let's write a report together. Han Bin said, as for whether you agree or not, that's the leader's business.

......

At ten o'clock in the morning, Han Bin and Zhao Ming came to Lu Jiaping's house again.

When Lu Jiaping saw Han Bin and the others, a surprised look appeared on her face: "Why are you two here again?"

"The transcript of the last time is not perfect, and some more questions need to be asked. Han Bin said.

"Heck, let's be honest with you, it's been so long, I can't remember. Lu Jiaping sighed.

"It doesn't matter if you can't remember, remember how much you say, as long as you don't lie, it's okay. Han Bin said.

"Officer Han, look at what you said, how could I lie. Lu Jiaping squeezed out a smile and invited Han Bin and the others to their home.

The purpose of Han Bin's coming this time is to make a transcript or second, mainly to get Lu Jiaping's DNA sample.

After asking about the suicide note and Lu Jiawei, I asked some more about the aftermath.

This time, the transcript was very fast, lasting only ten minutes.

After making the transcript, Han Bin opened his mouth and asked, "Zhao Ming, go collect some Ms. Lu's DNA."

Lu Jiaping was stunned for a moment, and said in surprise: "Officer Han, why do you want to collect my DNA." ”

"Routine. Han Bin said perfunctorily.

Lu Jiaping hesitated, but under Han Bin's strong request, she still agreed to Han Bin's request and asked Zhao Ming to collect DNA.

Then Han Bin and Li Hui left Lu Jiaping's house.

Out of the gate of Lu Jiaping's house, Han Bin glanced at his watch, then found a remote corner, and waited for half an hour, but Lu Jiaping's house did not move.

Han Bin then took Zhao Ming back to the sub-bureau and handed over the DNA to the technical team.

Not long after Han Bin returned to the office, Li Hui and Sun Xiaopeng also returned.

Han Bin got straight to the point and said, "How are the communication records checked?"

Lu Jiaping's family has a family of three, in addition to her husband, there is also a daughter, and the correspondence records of these three people have been printed, but they have not had time to study it. Li Hui said.

Han Bin glanced at his watch: "At about half past ten today, did Lu Jiaping make a call?" ”

Li Hui checked it and said, "Yes, it was called to his husband." ”

"After the two finished talking on the phone, did her old husband call anyone else?" asked Han Bin.

"Yes, mobile phone number 13514XXXXXX."

"Go check the owner of this mobile phone number. Han Bin said.

"Okay. Li Hui responded.

"Da ......" A sound of footsteps sounded, and Tian Li walked into the office.

Han Bin glanced at her and asked, "What's the matter?"

"Half and half. Tian Li shrugged her shoulders.

Han Bin immediately understood and asked, "Liang Zhibo's father's DNA was not approved for comparison with the deceased's DNA?"

"Yes. Tian Li nodded.

"I can't eat hot tofu in a hurry, let's take it step by step, and first compare the DNA samples of Lu Xiaojie, the deceased, and Lu Jiaping. Han Bin said.

"I'll arrange it. Tian Li answered, turned around and walked out of the office.

Speculation is speculation after all, and evidence is needed to support it.

However, before the DAN comparison results are out, Han Bin will not wait stupidly.

Han Bin asked for the communication record sheet and began to study the call record on it.

If Lu Jiawei is still alive, then it proves that Han Bin's speculation is right, then the suicide note must be Lu Jiaping, who was written recently, in other words, Lu Jiawei and Lu Jiaping's two sisters and brothers must be connected.

As long as you find the contact information of the two, you can find Lu Jiawei along the way......
