The school Zhang Ying attends is not far from the community. It takes ten minutes to walk straight from the school to the community, then turn into an alley to buy snacks or milk tea, which takes 15 minutes.

Yuan Jin looked back and forth three times to choose the route from school to home through the panoramic simulation system, then pulled over and asked Xu Yiran to get out.

"We have done information transfer simulations, and we have been here five or six times." Xu Yiran saw Yuan Jin's intention, her eyes lit up, and she asked curiously, "Dr. Lin, you found out during the interrogation.

What?"

"Call me Yuan Jin." Yuan Jin blinked and explained with a smile, "When I was in high school, there was a boy in my class who liked me very much, or had a crush on me. The streets near the school were similar to here, and every time I got out of school

He would follow me quietly. I was thinking, if Zhang Ying and the murderer knew each other, they would pass the message on the way home from school in the most secretive and safe way."

With the popularization of electronic products, many previous communication methods are gradually being eliminated.

Especially when there is more and more surveillance, the two people conspired to plan the murder, and the communication method is not online, it must be in reality.

"We have deduced this possibility. The Technical Department checked all the surveillance cameras in this area one week before the incident, and found no trace of the suspect." Xu Yiran smiled bitterly, "We also used a lot of psychological tactics during the interrogation.

, But Zhang Ying never let go."

Everything she could think of, the task force had thought of.

Querying all the monitoring systems was the one she had improved and upgraded. The accuracy and speed of facial recognition are incredibly fast.

"She spoke." Yuan Jin looked around casually and walked along the sidewalk. "She was actually very happy today. It's not that she was on guard as you thought. She had a brief moment during the second interrogation.

Excitement, this kind of excitement is the uncontrollable emotional fluctuation in the heart when the goal is approaching."

Zhang Ying was interrogated five times.

For a person who is deeply depressed but suddenly redeemed, the person who redeemed her can give her infinite strength.

This power gives her a sense of security and dependence, so her emotional disguises will become better controlled as the number of interrogations increases.

"I didn't notice it, I just felt that she was more defensive." Xu Yiran was surprised, "It turns out she is happy."

Yuan Jin patted her shoulder and explained to her the reason for Zhang Ying's excitement while walking.

There is only half a month left before the expiration of her detention period. When the time comes, she will be free.

The person behind her has never been in the police's sight from beginning to end. This is the good news that today's interrogation brought her.

They must bring the real murderer to justice before the expiration of the detention period. This person can use Zhang Ying to exonerate himself, and he may commit crimes again in the future.

"I think we should go meet her mother." After hearing Yuan Jin's explanation, Xu Yiran couldn't help complaining, "I have never seen such a mother. Her daughter committed murder and was imprisoned. She just received the notice

I’ll do it once and never ask again.”

"When a child who lacks love suddenly breaks out, someone must give her the love she wants." Yuan Jin comforted her, "Just think about what will happen if you walk on this road with the boy you like."

Xu Yiran blushed and whispered, "Singles have no idea."

Yuan Jin:……

Well, she is single too.

According to Zhang Ying's mobile phone payment records, she has purchased milk tea from every milk tea shop on this street. This habit did not change recently, but has lasted for nearly three years since she entered grade 7.

Yuan Jin put himself into Zhang Ying's state and led Xu Yiran through all three routes twice, stopping outside a milk tea shop.

Xu Yiran's heart beat faster unconsciously, "Anything discovered?"

She and her colleagues were responsible for the investigation of this case. They went through it several times and found nothing wrong.

"Passed the note." Yuan Jin tilted his head and smiled at her. He went in and ordered two cups of milk tea. He took out Zhang Ying's photo and asked the clerk if he recognized her.

"She doesn't come here often, but the little girl likes to lower her head when walking, and her face is always cold, so she has a bit of an impression." After reading the photo, the clerk looked at Yuan Jin suspiciously, "Miss, what's wrong with her?"

"There was a little accident. Can I ask if she acted strangely when she came to the store?" Yuan Jin smiled, "She's a little weird and different from other people."

"Yes, she doesn't come here often, but every time she comes in, she stands in front of the message wall for a long time." The clerk raised his hand and pointed to the message wall, "The last time she came, she tore off a message note."

Xu Yiran glanced at Yuan Jin in disbelief, showed her ID, and asked to see the surveillance camera in their store.

The clerk contacted the boss with shaking hands.

The monitoring in the store can only be kept for one week, and the original one has been overwritten.

The owner of the milk tea shop came quickly. Hearing that the store's surveillance might have captured the murderer, he actively cooperated and expressed his willingness to let them take the host back.

Xu Yiran had all the procedures in place, issued him a notice for obtaining evidence, and went with Yuan Jin to get the car with the host.

Back in the car, Yuan Jin took a sip of milk tea and started the car to go back to the community where her parents lived.

She was going to meet Zhang Ying's mother.

On the day of the incident, downstairs, the neighbors on the same floor made rumblings, saying that Zhang Ying's mother was not serious.

Human malice is never lacking.

Zhang Ying's mother is the regional manager of a well-known beverage brand. After the divorce, she lived with Zhang Ying. She had a house and a car, and she was considered a successful strong woman.

She did not remarry, but she had several boyfriends, each one younger than the last.

But the one I've been dating recently is obviously someone he wants to settle down with.

The man is about the same age as her, has no history of marriage, and is a project manager for an IT company. Divorced and raising a child, she actually found an unmarried man to marry. His financial strength is not bad, so it is inevitable that some people will be jealous.

The task force investigated this person and found no doubts. She wanted to verify it again.

Knowing that Zhang Ying exchanged information with the murderer using the message board of the milk tea shop, she still couldn't get Zhang Ying to speak. She had to make sure that the man who sent Zhang Ying the information was an acquaintance.

Probably because they were lucky, they met Zhang Ying's would-be stepfather who aroused the jealousy of others before even visiting.

The man is about 40 years old, elegant and handsome.

At that time, he and Zhang Ying's mother had just come back from outside, and their expressions were not very good, adding a bit of dignity.

Yuan Jin caught up and called Zhang Ying's mother, but was interrupted before she could introduce her identity. "I've finished what I have to say. If you are investigating a case, please show me your ID."

This is a woman with a strong personality. Yuan Jin judged her and said with a smile, "Ms. Zhang, you seem to be indifferent to your daughter's affairs."

"Police, please cooperate with our investigation." Xu Yiran showed her ID and tried her best to control her emotions.

Zhang Ying's mother is Zhang Yu, and she has been extremely uncooperative with them since the incident.

"What do you want to investigate? I wasn't the one who committed the murder. I've already told you everything I know." Zhang Yu's face turned pale. "If you continue to harass me, I have the right to file a complaint against you."

"The police are only doing this for Yingying's good, why are you doing this?" The man's face showed dissatisfaction, and his body became even more majestic.

Zhang Yu opened his mouth and pulled his boyfriend away.

She didn't want to be good to her daughter. She had the best school and the best tutor, and she worked hard for her. As a result, even if she committed a murder case, she also had a history of miscarriage, and she didn't consider herself a mother at all.

The two chatted and walked away. Yuan Jin shrugged and stood downstairs for a few minutes, calling Xu Yiran back to the criminal police team.

Zhang Yu's reaction was expected. There was no panic in her current boyfriend's eyes, only dissatisfaction with Zhang Yu.

It can be seen that he really wants to have a good relationship with his stepdaughter.

It's not that Zhang Yu doesn't love his daughter, he just doesn't know how to be a mother and doesn't know how to love his daughter.

After returning to the criminal police team after dinner, Yuan Jin spent several hours exporting the covered surveillance data of the milk tea shop and trying to restore it.

The night passed by in the blink of an eye.

All data from one month before the incident was recovered.

At dawn, Yuan Jin called everyone over to watch the footage captured by the milk tea shop's surveillance camera the day before the incident.

"How could it be a woman?" Xu Yiran and the others were stunned. Jiang Jiayue, who had also stayed up all night, almost dropped her jaw to the floor.

Over the past half month or so, the investigation direction of the case has gone completely wrong.

"It's not like I checked in the wrong direction. This person is a man." Yuan Jin zoomed in on the figure on the screen. "Look carefully at the features, his finger bones, crotch, and his feet."

Xu Yiran/Jiang Jiayue:……

A woman who is more refined than them in private is actually a man?

Yuan Jin picked up his mobile phone, opened the obscene men display website, uploaded a screenshot of the man's face and searched, and the results quickly popped up——

Cheng Jiaping, male, 25 years old, graduated from the Academy of Fine Arts in C Province. Before coming to Jiangcheng, he was imprisoned for a year for molesting a minor. After he came out, he was detained by the security for secretly filming.

"Yuan Jin, I know your website." Xu Yiran said and immediately sat back, "I have to look at the surveillance on the day of the crime again."

Who would have thought that the murderer was a man, but he didn't wear men's clothes.

"I'll go back and take a nap, and you guys can do the rest on your own." Jiang Jiayue yawned and teased Yuan Jin, "Master, are you accepting a disciple?"

"Stop." Yuan Jin was infected by her and also yawned, "Go back to sleep."

Jiang Jiayue waved and left.

A major breakthrough was made in the 5.8 minor homicide case, and everyone in the task force became busy.

After breakfast, the project team was divided into three groups.

One group went to the detention center to interrogate Zhang Ying, one group went to monitor the suspect, and the other group stayed in the team to check why the suspect's sample was not included in the DNA database.

Yuan Jin and Xu Yiran caught up on their sleep and rushed to the detention center. It was already 11 a.m.

When Zhang Ying was brought over, she had an impatient look on her face and black circles under her eyes.

Yuan Jin said hello to her and chatted with her as he did yesterday, slowly leading the topic to her favorite milk tea.
