If you want to overturn Lu Jing's case, finding the murderer's motive is the most important thing.

The role that the forensic doctor can play is very limited.

Xie Qing simulated the process of the murder twice in his mind, and then followed the large team to conduct a detailed search of the whole house.

The hostess is not very diligent, which can be seen from the stove. The cement wall is covered with thick grease.

Tan Yi stood by the cupboard for a long time, as if he found something.

Xie Qing glanced and said, "There should have been a porcelain oil pot here, and the remains are in the dustpan over there."

Tan Yi smiled slightly, "You are very observant."

Xie Qing said, "Captain Tan, you are great." He went to the bedroom first, and then looked at the main room, and Xie Qing looked at the main room first, so he was naturally one step ahead of him.

Everyone exchanged places, and Xie Qing entered the east bedroom.

There was a large kang on the south side of the room, and an outdated and dilapidated high-low combination cabinet was placed against the north wall.

The curtains were drawn on the windows, but not tightly in the middle, revealing the plastic sheet nailed to the window.

The three quilts on the kang were still there, one alone at the head of the kang, and two next to each other at the end of the kang, at least one and a half meters apart.

The floorboards on the kang were covered with a thick layer of dust.

Everything was there, and nothing was there, a family was broken up like this.

...

The four people searched the entire house, found nothing, and had to retreat.

Lu Jing was right, his family was indeed not rich, and only had an old TV worth a few dollars.

There was no sign of rummaging at the scene. Wei Fenfang's bag contained 31 yuan, and Lu Jing's coat pocket contained 22.3 yuan.

A family only had so much money, so there was no possibility of murder for money.

As soon as everyone walked out of the door, a middle-aged couple quickly came to meet them.

The man asked rudely, "How many of you are from the police station?"

Li Ji said, "We are criminal police officers from the municipal bureau. My last name is Li. What's yours?"

The man said, "My last name is Wei, Wei Zhiping, the eldest brother of Wei Fenfang. I heard from the neighbors that someone came here, so I came to ask.

" The woman also spoke, "Officer, I heard that Lu Jings did not plead guilty. Are you trying to overturn Lu Jings's case?"

The man got emotional when he heard the word "overturn his case" and jumped up and said, "He killed my sister. That bastard is not a human being. My sister has never had a good day since she married him. If you overturn his case, you will be conscienceless!"

His voice was extremely loud and disturbed.

Dogs in the distance started barking, and the doors of Lu's neighbors on both sides also opened one after another.

Someone in the shadows supported the man, "Yes, that guy drank some cat urine for no reason and then beat people after drinking it. Fenfang suffered a lot. He must have killed the person accidentally!"

"Yes, it must be. He is just a thief crying "stop thief". Officer, don't believe him."

"That guy is a coward who only bullies the weak and fears the strong. Now it's his turn to die. He is scared and complains. He deserves to be shot!"

...

wait until the discussions stopped.

Tan Yi spoke, "Don't worry, everyone. First of all, the case was handed down by the Procuratorate, and they asked our Municipal Bureau to reinvestigate it. But reinvestigation does not mean overturning Lu Jing's case, but rather completing the key evidence in this case. There are two results of completing the case. One is to leave Lu Jing speechless, and the other is to bring the real murderer to justice. Either way, it is to redress the victim, don't you agree?"

Tan Yi is not good at making long speeches easily, but when he does, he has a set of ideas, and his words are sincere and reasonable.

Wei Zhiping's mood stabilized a little. "What the police officer said makes some sense. What have you found?"

Tan Yi did not answer but asked, "Does your sister have any enemies, or close friends?"

Wei Zhiping said, "What do you mean?"

Tan Yi said, "Generally speaking, most homicides are committed by acquaintances, either for money, sex, or some unspeakable secret."

Wei Zhiping's wife said, "Fenfang has good relationships with people. She has quite a lot of junior high school classmates who she gets along well with. The police from these branches have investigated."

Wei Zhiping nodded. "In the past few days, our whole family has been thinking about this matter over and over again. But my brothers and sisters each have their own families and we don't get together very often. I don't know how her interpersonal relationships are in the factory."

Several neighbors came over.

Tan Yi asked them, "Does anyone know?"

A younger aunt said, "Fenfang brought her friends back. I saw two or three of them. They were all women in their early twenties. It's unlikely that they would kill anyone."

"Yes, yes, yes." An older woman also spoke up, "I saw one too. She said she was a colleague of Fenfang's. She went home to get her pants. I saw her open the door and asked a few questions at the time."

Tan Yi said, "If you saw them, would you still recognize them?"

The older woman said, "It's hard to say. It happened about half a month ago. They just walked by and didn't say much."

Tan Yi asked, "Didn't anyone hear anything unusual that night?"

The older woman said, "My house is next door. I really didn't hear anything. It was around 4:30 when Lu Jing started yelling. That's when we all knew that Fenfang was in trouble."

...

Back at the Municipal Bureau, the four of them held a small meeting and formally read through the case file of Lu Jing murdering his wife. They had not read it carefully before because they were afraid of being influenced by the conclusion of the branch bureau and solidifying their thinking.

Compared with the investigation of the branch bureau, Tan Yi and others made the following discoveries: First, the fibers on the glass; second, Wei Fenfang's colleagues had been to Lu's home.

The fibers had to wait for the technical laboratory to test them.

Wei Fenfang's colleagues could conduct a deeper investigation, but the crime happened after dawn, and it was difficult to find time witnesses to prove his innocence or guilt.

Li Kesheng lay on the table in despair, "I never thought that such a case would come up before the New Year."

Li Ji leaned back in his chair and said quietly, "What do you think, could it be suicide?"

Xie Qing put down the autopsy report, "The deceased weighed less than 100 pounds, was 1.56 meters tall, and was relatively thin. There were no cuts. It is almost impossible that the knife hit her heart. In addition..." She pointed at the photo of the corpse, "Judging from the position and angle of the knife, the murderer would not be very short. Objectively speaking, Lu Jing is indeed a big suspect."

Li Ke sat up and snorted coldly, "If she wanted to commit suicide, she might as well kill Lu Jing."

Tan Yi said, "Li Ke, remember to hand the fiber over to the technical department. Li Ji will go to the brewery with me tomorrow, and Xie will go to the funeral home. That's it for now, everyone go to bed early."

"Let's go." Li Ke stood up.

Xie Qing handed the autopsy report to Li Ji and put it away together. She called the funeral home and went back to the dormitory with Li Li.

She called the two to her room and took out the remaining two envelopes. "Tomorrow is the New Year, I will return the money first, you can count it."

The two of them were very loyal. They knew that she was richer than them, but they still took out all their savings.

Li Ji disagreed, "Can you still neglect us?"

Li Ke said, "It's better to count it. My mother said that brothers should settle accounts clearly. The money must be counted in person to avoid any problems later and make everyone unhappy."

Xie Qing raised her eyebrows. Li Ke's mother was an intellectual and had done a good job in educating her daughter.

Li Ji accepted the advice, took them out and counted them, "Why are there so many?"

Li Ke said, "Yes, why?"

Xie Qing said, "My brother has been speculating in stocks recently. You can check the market index on the day I borrowed the money and the market index today, and do the math, and you will know that the money is what you deserve. I made some money, so I took you along."

"My brother said that now is the high point, and if we invest again, we will lose money. You understand what I mean, right?"

Li Ji said, "Are you afraid that we will speculate again after we have tasted the sweetness?"

Xie Qing asked back, "Don't you know how to do that?"

Li Ji shook his head, "My mother has calculated for me, and I don't have the destiny to make extra money. I have never won playing poker since I was a child."

Li Ke said, "It is impossible for me to speculate. I don't understand anything. What should I speculate for?"

Well, one is self-aware and the other is feudal and superstitious.

Worrying in vain!

Xie Qing said, "In that case, please keep it a secret for me, so as not to mislead others. That would be fatal."

Li Ji said, "Don't worry, what if everyone comes to look for you if this gets out? I can't take such responsibility."

Li Ke pouted and nodded, "It's better to have less trouble than more."

"Okay!" Xie Qing waved her hands, "Kneel down, kids."

...

Li Ke and Li Ji gave Xie Qing a slap on the face respectively and left her dormitory together.

Li Ji was very satisfied, "Xiao Xie is so kind. I have new clothes to wear for my blind date this year."

Li Ke collected the New Year's money every year, and he didn't feel much about the extra 800 yuan. He just looked at Li Ji with sympathy, "How old are you? You are going on a blind date now."

Li Ji said, "It's too late. If you don't go on a blind date, the good ones will be picked up by others." Li Ke

shook his head, "That's true. My mother said so too. I wish you a smooth blind date?"

Li Ji shook his head, "Your brother is so handsome, of course it will be smooth."

"You are so conceited." Li Ke entered the dormitory and closed the door without looking back.

Li Ji was not convinced, "How can I be conceited? Although I can't get you, there are many people who want to get me."

He shook the envelope and walked back happily.

...

The next afternoon, Xie Qing and Cao Haisheng went to the anatomy room together.

Because they had informed the deceased in advance, the body had almost completely decomposed.

The master and his apprentice re-examined the body together.

There were slight injuries around the lips of the deceased - these were mild contusions caused by covering the mouth.

The stab wound was diamond-shaped, consistent with the murder weapon in the photo, and the puncture in the clothing was consistent with the stab wound.

The wound was located on the upper side, and the stab wound had an angle. Based on this, the forensic doctor of the branch judged that there was no problem in judging that the murderer was tall.

The stab wound was longer than the murder weapon, and it was obvious that the murderer did not spare any strength when stabbing.

The cause of death was heavy bleeding caused by heart injury.

There were no resistance injuries on the body, and the murderer seemed to have killed Wei Fenfang in a single encounter.

Cao Haisheng straightened up and took off his gloves. "There are no suspicious spots on the body. We can do a scene simulation."

"Okay." Xie Qing found a few forensic photos of the scene. "If the murderer is not Lu Jing, then this door must not be locked. After the murderer jumped over the wall and sneaked into the main room, he happened to be heard by Wei Fenfang who couldn't fall asleep at night. The sound of Wei Fenfang putting on her shoes failed to scare the murderer away. Instead, he took the knife on the stove and waited at the door. As soon as Wei Fenfang came out, he gave her a fatal blow."

"The murderer was afraid of waking up Lu Jing, so he covered Wei Fenfang's mouth, dragged her to this position, and knocked her down... After she stopped making any sound, he left the Lu family along the same route. At around 4 o'clock, Lu Jing was awakened by the urge to urinate, and when he got up, he was tripped by Wei Fenfang. He found a knife in the middle, and in a panic he pulled out the knife, leaving fingerprints."

Cao Haisheng said, "The process is reasonable, but what was the murderer's motive for committing the crime? Well, forget it, this is something that Captain Tan should consider, so let's not worry about it."

Xie Qing nodded, "Call it a day!"
