In the case of Li Xiaonuan, Wu Honglin was considered the most important suspect because he appeared in the area of ​​the crime scene during the time of death.

However, Cai Xin's death was equivalent to clearing his suspicion in disguise.

Then, Jian Jing's previous speculation on the time of Li Xiaonuan's death was greatly increased.

Maybe Li Xiaonuan did not die at night.

Letting her eat at noon can confuse the estimated time of death. In addition, in the snowy weather, the body was first frozen and then burned, and it was impossible to detect from the body's reaction. A slight manipulation can create the illusion that the murderer could not catch up after the snow.

The murderer took great pains to create an alibi, undoubtedly to clear himself of suspicion.

Therefore, the person who did not have an alibi in the afternoon and had one in the evening is the most suspicious.

Unfortunately, after ten years, the memory of the case by the relevant personnel has become vague, and many clues cannot be retrieved once they are missed.

But can the same idea be applied to this case?

The case is so similar.

Based on the same inference of stomach contents, is it possible that Cai Xin's time of death is wrong?

It seems not.

Cai Xin appeared in Yu Can's store from 2pm to 2:40pm, and more than one person confirmed that she was still alive. Even if the murderer was eloquent and tricked her not to board the plane for the time being, and let her eat dinner, then there should be other food residues in her stomach.

Unless dinner and afternoon tea are exactly the same.

Who knows what afternoon tea is for? People in Yu Can's store, including Yu Can.

In terms of alibi, Yu Can is undoubtedly the most suspicious.

Although it may be cruel to think so, the fact is that she is the only person involved in the Li Xiaonuan case and Cai Xin case besides Zhao Bin.

Of course, it is also possible that the former led to the latter.

But the investigation must be objective. Is Yu Can a suspect?

She returned to the store at 3:20 pm and left at 7-8 pm. It is impossible for her to kill anyone during this time. Assuming that she found Cai Xin as soon as possible after work and let her eat a dinner that was exactly the same as afternoon tea, then she would not be able to do it until 10-12 noon at the latest.

Even if she killed someone at 10 o'clock, Ji Feng found her at her home at 10:25.

The scene of the body dumping is at least a 40-minute drive from Yu Can's home, and there must be no traffic jams.

This alibi is too strong. Even if Yu Can is confirmed as a suspect, it is difficult to solve, not to mention that she is not that suspicious now.

"Didn't the autopsy report say that there were sleeping pills?" Jian Jing rubbed his forehead and changed his mind. "The person who made her drink it without any defense must be her acquaintance. Did the surveillance at the subway station capture anything?"

Ji Feng said, "You can't park near the subway station. Yu Can said she parked it at the intersection ahead. I went to the traffic control office to check the surveillance. Just as she said, Cai Xin was in the car at the time and she is still fine."

Jian Jing was silent for a while.

After a moment, he said, "I insist on two points now. First, the murderer is an acquaintance of Cai Xin, otherwise there is no need to use exactly the same killing method. It is the most difficult to investigate when a stranger commits a crime, right? Only a serial killer can divert the police's attention away from the people around the deceased."

Ji Feng nodded.

"Second, the murderer wants to use this case to clear himself of suspicion. Who is the suspect now, but has no alibi?"

Ji Feng said helplessly: "We haven't started investigating her social connections yet. Yu Can mentioned Zhao Bin in her confession. The leader means to investigate this person first. He is very suspicious."

Jian Jing said: "Maybe this is what the murderer wants. But what's the use?"

She was puzzled: "The case has already become an unsolved case. If another person dies, the investigation will definitely be reopened. It's not like 2007. It's true or not. There is no Wu Honglin to take the blame. What's the use of buying some time?"

"Escape." Ji Feng looked at the gloomy sky and patted her shoulder. "It's going to snow soon. I'll go watch Yu Can. You go home. I'll call you if there's anything."

Jian Jing glanced at him and couldn't help saying, "I don't mean to steal your job. Look at yourself." She took out her small mirror and looked at him. "It looks like you haven't slept for half a month."

Ji Feng touched his chin.

She: "... You haven't really slept for half a month, have you?"

"I slept, it's okay, it's nothing." He smiled.

Jian Jing: "Staying up late will shorten your life."

Ji Feng laughed: "Why live so long? That's enough." He glanced at his watch, "There's a meeting at five o'clock. It's time to go back."

Jian Jing said, "I'll take a look at the scene. You can go."

Ji Feng didn't force it: "Leave early, be careful of catching a cold."

She waved her hand impatiently and told him to get out.

Ji Feng left and went back to the branch for a meeting.

Every time a big case came up, the superiors would come down to organize the investigation. Before that, some basic situations needed to be investigated clearly, explained clearly at the discussion meeting, and then the direction of the investigation could be determined.

Because it involved an old case, this meeting was extremely lengthy.

The forensic doctor talked about the autopsy report, the criminal detection technician talked about the traces at the scene, and Lao Gao started with the case in 2002, introducing the four victims one by one.

Ji Feng talked about Liu Meng's investigation results, and mentioned Jian Jing's views on the Li Xiaonuan case.

The leader held a thermos cup in his hand and listened very seriously, but he didn't say a word, which made everyone feel uneasy.

It was already past eleven o'clock when the matter was over.

Ji Feng couldn't hold on any longer, so he chopped down two mouthfuls of instant noodles and went back to the duty room to sleep. He

had a deep dream, and the sky and the earth were a cold silver-gray.

It took him a long time to realize that it was snowing.

The snow was gloomy, like unsolidified cement. Several charred corpses lay in the ruins, looking like burnt firewood sticks.

He just stood there, watching silently, until he woke up from his dream. His back and waist ached

all over.

After running around outside for half a month, he came back to work non-stop, which was too much for even an iron man.

Ji Feng climbed up with difficulty, and his bones creaked.

He took out a toothbrush and toothpaste from the cupboard and went to the bathroom to wash up. While he was brushing his teeth, Lao Gao came in with a slightly stiff expression.

Ji Feng glanced at him and brushed his teeth.

Lao Gao: "Uh, I had something to do this morning..."

"Pfft." He spat out the toothpaste foam and asked calmly, "Can you let me recuse myself?"

Lao Gao nodded with difficulty.

When he reported the case yesterday, he deliberately left out Zhang Peiru's matter, but the case file was there. As long as the leader's eyes were not blind, he would definitely know about this situation.

The relationship between Ji Feng and Li Xiaonuan's case is still unclear. My father has a clear interest in it. Considering the rigor and fairness of the case, he must be allowed to recuse himself from the investigation.

"Okay, I guessed it." He closed his eyes, "Then I'll take it as a paid vacation."

Lao Gao was very upset: "Dream, there are other cases."

"I'm not in the mood to investigate, so I'll take two days off." He moved his stiff neck, "I'm almost getting a stiff neck from sleeping on this hard bed."

He looked normal, but Lao Gao didn't take it seriously, and hesitated: "Or... I'll apply for Teacher Jian to participate?"

Ji Feng shook his head.

Lao Gao sighed and patted his shoulder: "Okay, go home and rest for two days. It's a rare vacation."

Ji Feng said "hmm" and didn't say anything else.

However, although he said he was going home to rest, he still stayed in the office honestly in the afternoon, making phone calls and typing on the keyboard, which was not much more free than going out. He

got off work on time at 5:30, and encountered the evening rush hour.

On the crowded street, Ji Feng looked at the magnificent sunset in the west, and a scene from a long time ago emerged in his mind.

That day, his father and mother divorced.

Ji Yunyun was ignorant and was sent to live with relatives, and only Ji Feng accompanied them.

His mother said, "Xiao Feng, don't blame me."

He said, "I don't blame you."

Really not.

Compared to his father who knew nothing, he actually discovered his mother's illness a long time ago. She had cancer and needed a long time of treatment and recuperation.

Ji Liming was a policeman and couldn't take care of the family. She could take care of the children before, but what about after she got sick? So he filed for divorce very forcefully, and didn't want any children.

The second month after the divorce, she married another man.

The man had pursued her for a long time and knew that she was sick, but he didn't care. He just wanted to be with her in the last moments of his life.

She hoped to spend the last few years of her life with her family by her side, and there was no reason not to agree.

Ji Liming was shocked to find out that his wife was so seriously ill until she died.

He regretted it, but was sadly glad that they were divorced. How much time could he spend with her? It would be too sad if her husband was not by her side at the last moment of her life.

Was there a sunset like this on the day of the funeral?

Ji Feng thought about it for a moment, then shook his head. He couldn't remember.

The car moved slowly, and the traffic lights changed. It took more than an hour, and the sun had completely set, before the car finally drove home with difficulty.

There were people at the door, all of them were quite tall.

Yunyun and who? Yu Can?

Ji Feng frowned, stopped the car immediately and walked over.

"Ms. Yu, why are you here?" He looked at Yu Can.

She was wearing a long black down jacket, flat boots, and holding an LV handbag. She looked stylish and beautiful, which attracted the guard's glance.

Yu Can hurriedly said, "Officer, I heard about your father's situation... I'm sorry." She was ashamed, "I didn't know my testimony would lead to such a result..."

Ji Feng said, "It's all in the past." He winked at his sister, and Ji Yunyun immediately said, "Yes, you are too polite. I can't accept your things."

As he spoke, he pushed away the foam box.

"It's not something valuable. It's strawberries my friend brought from the countryside." Yu Can said, "I originally wanted to give it to my daughter, but who knew..."

Her eyes reddened and she quickly lowered her head to wipe her tears: "You can eat it, don't be polite."

Ji Feng said, "We can't accept it."

"You can't take back something you gave away." Yu Can waved her hands, forcibly handed it to Ji Yunyun, and then said, "Officer, actually I came here today because I want to talk to you about something, do you think you can..."

She gestured to the lively neighbors around her and smiled bitterly.

Ji Feng didn't know why she came. After a brief thought, he was unwilling to miss the clue and nodded, "Okay." He made a wait gesture and said to Ji Yunyun, "You go home first."

Ji Yunyun whispered, "What should we do with this box of strawberries?"

He hesitated and said, "Put them in the carport."

She nodded.

Ji Feng didn't give her a chance to ask more questions. He waved his hand and followed Yu Can.

Yu Can invited him to get in the car.

"That's not necessary. Just tell me what you want to say." Walking to a quiet street corner, Ji Feng went straight to the point, "It just so happens that I have some questions to ask you."

Yu Can shook her head: "Let's get in the car. I want to take you somewhere."

Ji Feng raised his eyebrows and suddenly said: "Why don't I ask first? "

She smiled: "Okay."

"I called Huang Sheng - oh, the owner of the training class who hired Li Xiaonuan, why did he want to hire Li Xiaonuan and how did he find her? Guess what he said?" Yu

Can asked curiously: "What did he say?"

Ji Feng said: "He said that an agent recommended it to him and gave him a few flyers."
