After returning to the second group office, Han Bin immediately convened a meeting.

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

"I went to the Zheng team's office. In order to have a deeper understanding of the 715 case, the Zheng team invited the person in charge of the 715 case that year and told me some of the investigations of the year." Han Bin said.

"The person in charge of the 715 case back then seems to be Ding Xifeng." Tian Li remembers the signature of the person in charge on the file.

"Not bad." Han Bin replied.

"How do I feel that this name is a bit familiar," Li Hui muttered.

"Senior Ding was the person in charge of a major case ten years ago. He is probably the leader now," Zhao Ming guessed.

Han Bin did not sell Guanzi either, introducing: "He is now the deputy captain of the city criminal investigation detachment and the captain of the municipal criminal investigation team."

"My day, so awesome!" Zhao Ming said in surprise.

"Let me just say it, I seem to have heard it somewhere." Li Hui muttered.

Tian Lixin is relatively thin and frowns: "Captain Han, what does it mean that Captain Ding came to our branch?"

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

"Doesn't that mean that if we solve the case, Captain Ding will have a contribution." Zhao Ming said.

Han Bin smiled and said, "Don't worry, Captain Ding can't take any credit for this, as long as you don't make a mistake."

There are two meanings in Han Bin's words. The first is that there is no error, which means that there is no error in the investigation; the second is that there is no error, which means that Ding Xifeng has the idea of ​​fixing the situation.

Since Ding Xifeng is here, he must be named, so even if Han Bin and others found new clues and overturned the investigation direction of the case that year, it was done under the guidance of Ding Xifeng.

For this case, Ding Xifeng did not seek merit but no demerits.

The person in charge of the case is Han Bin. This is definitely not possible. I knew that Zheng Kaixuan was investigating the case. Now there is another Ding Xifeng. As long as Zheng Kaixuan has no opinion, it will not affect Han Bin in any way, nor will it affect him. The credit.

With Han Bin's remarks, everyone has a bottom.

The people present are not stupid. The people who handled the 715 cases in the past have basically become leaders. If the people in the second group just want to do meritorious service and overthrow the original investigation direction of the case, even if they solve the case and do meritorious service, they will have a good appearance. , Maybe it has been recorded in a small book by a certain leader.

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

A brief introduction to the situation, the morale of the second group of players also recovered, Han Bin began to arrange tasks.

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

"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 the location of Lu Jiawei and arrest the other party.

"Zhao Ming and I went to Lu Jiaping's house again, made another transcript for her, and extracted Lu Jiaping's DNA."

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

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

"Let's write the report together." Han Bin said, as for the same disagreement, it is a matter of leadership.

...

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

Lu Jiaping saw the two of Han Bin, with a surprised look on her face: "Why are you two here again?"

"The transcript last time was not perfect, and we still need to ask some more questions." Han Bin said.

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

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

"Officer Han, depending on what you said, how could I lie." Lu Jiaping squeezed a smile and invited both Han Bin to the house.

The purpose of Han Bin's visit this time was to make transcripts second, mainly to get a DNA sample of Lu Jiaping.

After asking about the suicide note and Lu Jiawei.

This time the transcript was very quick and lasted only ten minutes.

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

Lv Jiaping was stunned for a moment, and said in surprise: "Police Officer Han, why are you collecting my DNA?"

"Routine." Han Bin said perfunctorily.

Lv Jiaping hesitated, and at Han Bin's strong request, he still agreed to Han Bin's request and let Zhao Ming collect DNA.

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

After leaving the door 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 took Zhao Ming back to the branch and handed the DNA to the technical team.

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

Han Bin said straightforwardly: "How's the communication record check?"

"Lu Jiaping has a family of three. In addition to her husband, there is a daughter. The correspondence records of these three people have been printed out, but they have not had time to study." Li Hui said.

Han Bin glanced at his watch: "At around ten thirty today, did Lu Jiaping make a call?"

Li Hui checked and said, "Yes, I called his husband."

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

"Yes, the phone number is 13514XXXXXX."

"Check the owner of this phone number." Han Bin said.

"Okay." Li Hui replied.

"Da da da..." With a sound of footsteps, Tian Li walked into the office.

Han Bin took a look at her and asked, "What? How about the application for DNA testing?"

"Half and half." Tian Li shrugged.

Han Bin immediately understood and asked, "The application for comparing Liang Zhibo's father's DNA with the deceased's DNA failed?"

"Yes." Tian Li nodded.

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

"I'm going to make arrangements." Tian Li replied and turned and left the office.

After all, speculation is speculation, and evidence is needed.

However, Han Bin wouldn't be silly to wait until the DAN comparison failed.

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

If Lu Jiawei is still alive, then it proves that Han Bin’s speculation is correct. Then the suicide note must have been written to Lu Jiaping only recently. In other words, Lu Jiawei and Lu Jiaping must be connected.

As long as you find the contact information of the two, you can follow the vine to find Lu Jiawei...
