Forensic Doctor Qin is a forensic physician of the Provincial Public Security Department, and he has a wealth of experience in both practice and work.

In particular, he gave his own investigation ideas for this case based on a homicide case that he had participated in the detection.

"If you start the investigation from the close relationship, it will be much easier to do, and you can know a family of four at the same time, this scope is still relatively limited." Ling Zizhen nodded, and a confident smile immediately appeared on his face.

Lu Ke was also a little excited, and added: "Coupled with the height characteristics of about 1.85 meters, it is very easy to identify. Also, didn't we find the murderer's bloody footprints at the scene? ”

But hearing this, Ling Zizhen shook his head slightly, and explained in a deep voice: "The footprints at the crime scene can be used for accusations, but they cannot be used for investigation. Even if there are some characteristics, a lot of comparison is required. However, when the murderer is found, he can compare the traces of the bloody footprints with all his shoes to find important stride length features that can be used to convict. ”

After hearing this, Forensic Doctor Qin slowly stood up and said, "Then let's do it first, there are only so many inferences we can get through the autopsy, and the rest depends on you." ”

Lu Ke also stood up and said in a deep voice: "Thank you very much for the support of the forensic doctor of the provincial department, I will take the two of you to dinner for your hard work." ”

Forensic Doctor Han smiled and waved his hand: "Let's just go by ourselves, you still have work to do, so you won't be troublesome." ”

Forensic Doctor Qin turned around and left his seat and asked, "Does Forensic Doctor Jiang want to be together?" ”

Jiang Xiran's face turned pale, and he tried to cheer up: "No." ”

Lu Ke hurriedly said, "That...... Zhou Xiaoyi took two forensic doctors to dinner. ”

"Okay!"

Zhou Xiaoyi was also hungry, and immediately cheered up after hearing this.

He stood up and beckoned to the two forensic doctors: "Please two of you, I'll take you two." ”

Forensic Doctor Qin and Forensic Doctor Han left, and Ling Zizhen also stood up and said, "Team Lu, then I'll also go back to the trace examination department first, and some traces of the scene were still found at the scene of the murder this time." ”

Lu Ke raised his chin at him and said in a deep voice, "Okay, you can go." ”

Ling Zizhen turned around and left, and only Lu Ke and Jiang Xiran were left in the task force office.

Lu Ke also stood up, walked towards Jiang Xiran, and took out a box of juice from his pocket: "How is it?" It doesn't matter, right? ”

Jiang Xiran shook his head weakly, and said lightly: "It's okay, just rest for a while." ”

Lu Ke opened the juice, handed it to her, and asked with concern, "Are you really okay?" Do you want to go to the hospital? ”

Jiang Xiran took the juice, took a sip, and said weakly: "The forensic doctor is also a doctor, my body knows it by itself, it is low blood sugar, just rest for a while." You go and get busy, the autopsy is done, and it's time for you to go on next, I'm afraid you'll have to stay up all night. ”

Lu Ke looked at her seriously and said with concern: "Don't brace hard, pay attention to rest, your body is important." Then I'll go first, and call me if there's something. ”

Jiang Xiran nodded: "I'm fine." ”

At present, the direction of the police investigation is mainly on investigating the social relations of the deceased's family, and contacting the deceased Wu Changhai's eldest son-in-law Bian Yongshun and youngest daughter Wu Xiaodong. But since the incident, it has been nearly 12 hours, and the two have still not been contacted.

This can't help but think about what the two people who disappeared have to do with this case. Is there still some unknown relationship between brother-in-law and sister-in-law?

In the office of the criminal police team, Su Simeng walked in quickly and brought back a clue.

"Team Lu, I just investigated Wu Changhai's news on our internal Internet."

This was the first important information investigated after the incident, and Lu Ke hurriedly asked him: "What is the content?" ”

Su Simeng held a document in his hand and summarized: "A week ago, Wu Changhai reported a company suspected of illegal fund-raising and tax evasion, and now the city's economic investigation detachment and tax authorities have intervened in the investigation. ”

Lu Ke hurriedly took the information, which showed that Wu Changhai reported a financial investment company, and the legal person was called Nie Zhiyi.

He looked at the information, raised his head and said seriously: "The financial investment company, judging from the company's situation and business scope, is somewhat similar to Wu Changhai's financial company. ”

Su Simeng nodded, and then added: "And through the expanded investigation of Wu Changhai and Nie Zhiyi's identity information, it was found that these two people have known each other for many years, and their companies have had a cooperative relationship for many years before, and more importantly, the two have a very good personal relationship. ”

Lu Ke flipped through the information in his hand and smiled faintly: "People die for money, birds die for food, it seems that it is another story of brothers against their goals." ”

The corners of Su Simeng's mouth slowly raised, and he couldn't help laughing: "No matter what happened between the two of them, judging from the facts of the case alone, Wu Changhai's report on Nie Zhiyi had a great impact on Nie Zhiyi's company, and it was very likely that he would be imprisoned, which was enough to become Nie Zhiyi's motive for killing." ”

Lu Ke closed the information in his hand, and his expression became extremely serious: "This is definitely a major discovery, take a detective team, let's go to Nie Zhiyi's house to have a look." ”

Su Simeng said in a deep voice: "Okay, I'll arrange it." ”

Fifteen minutes later, two police cars slowly started and drove towards the city center.

"I have been in contact with the economic investigation detachment, and now Nie Zhiyi's financial investment company is in the stage of temporary seizure, and Nie Zhiyi has been restricted from leaving the market until the end of the investigation. So, now Nie Zhiyi is at home. ”

In the car, Su Simeng communicated Nie Zhiyi's details with Lu Ke.

Lu Ke nodded and said seriously: "Let the detective team prepare for the arrest operation, and if it is determined that Nie Zhiyi is suspected of committing a crime, arrest him immediately." ”

Su Simeng patted the police pistol on his waist and said with a smile: "Don't worry, it's all arranged." ”

The address of a big boss like this is relatively easy to find, and Nie Zhiyi is no exception, the police car drove into Nie Zhiyi's community and quickly found his home.

The detective team was armed with police weapons and stood on both sides of the door to deal with emergencies, and Su Simon stepped forward and knocked on the door.

"Who?"

No sooner had there been a knock on the door than a woman's voice came from inside.

"There's someone else in there." Lu Ke hurriedly pushed his hand to the detective police officer behind him, signaling not to act rashly.

Su Simeng did not answer and continued to knock on the door.

Immediately after, footsteps were heard, and the door lock opened.

"Who?"

As soon as the woman's words fell, Su Simeng pulled the door open, his eyes fell on the woman first, and then looked into the room.

"Police."

Lu Ke stood behind Su Simeng, and while showing his documents, he also took a step forward.

The woman looked at Su Simeng and Lu Ke with some confusion and asked, "You ...... Is there something wrong? ”

Su Simeng leaned out and swept around the living room, but he didn't find Nie Zhiyi's figure, and then asked, "Is this Nie Zhiyi's home?" ”

The woman nodded, didn't ask anything more, turned sideways to let out the passage at the door, and shouted into the inner room: "Old Nie! The police are here again! ”

It seems that police visits have become a norm, and women are no longer surprised.
