After saying that, Jiang Chengyi went back to the room, and when he came out, he was answering the phone with a stack of documents in his hand.

Lu Yan saw that he had no plans to cook, and remembered that the two of them hadn't had lunch yet, so she went to the kitchen to prepare.

When Mrs. Liu left in the morning, she left a bowl of something like a stew and put it in the refrigerator.

Lu Yan had seen it for a long time. Out of curiosity, she opened it and saw it. She only recognized that there was sauce like abalone in it, but she didn't know what it was for.

Just as was about to cook some home-cooked food for the couple, the phone at the dining table rang.

She came out and saw that it was an unfamiliar number, hesitated for a while, but picked it up.

"Miss Lu, guess who I am?"

It was a man, and a man with a very pleasant voice.

I only heard it last night, so it was very familiar. Lu Yan was surprised and said, "Yu Baifeng?"

Jiang Chengyi was answering the phone over there, holding something like a USB flash drive in his hand. Hearing Lu Yan's voice, he looked over here.

Yu Baifeng seemed to have just woken up, and his voice was still a little rusty, even more sexy and charming: "I'm so happy, Miss Lu still remembers me."

How could he have her phone number? Lu Yan's face was full of confusion.

Da Zhong and Tang Jie would not make their own decisions, and she herself did not have the habit of casually giving people her phone calls. After much deliberation, only Senior Wen Peng was the most suspicious.

She politely replied, "Mr. Yu, good noon."

Yu Baifeng smiled lowly: "Are you free on the weekend, no no, don't be too busy rejecting me, Miss Lu, you've only met me once, and you don't know me well enough, in fact, I'm... far better than you think. Be good."

Lu Yan laughed dryly: "Mr. Yu, I haven't eaten—"

"Please watch a movie on the weekend. The premiere of "The Stars Are Bright" starring me. Miss Lu, I know you are very busy, but your life needs to be adjusted. I bet you will like this film."

Jiang Chengyi threw the USB flash drive and the stack of documents back to the coffee table, and walked coldly to the restaurant. When he passed Lu Yan, he gave her a meaningful look.

Lu Yan turned sideways and said to the phone, "Mr. Yu, I have to go to work on weekends, and I don't like watching movies very much, but thank you for your kindness."

After hanging up the phone, only to find that Jiang Chengyi had taken out the bowl of stew from the refrigerator.

didn't mean to cook just now, it would seem like have to do it self.

Lu Yan didn't let her gaze stay on his thin waist and expressionless side face for too long. She returned to the room, took out the computer, and sat down at the dining table.

The meal will be ready soon.

Obviously, Jiang Chengyi not only knew how to handle that bowl of stew, but also handled it quite beautifully.

He made two plates of rice with abalone sauce.

The thickness of the abalone sauce is right, the color is authentic, and even the rice and broccoli go well together.

Lu Yan picked up the spoon and scooped a mouthful of it into her mouth. She felt that the juice had a strong aroma and was so sweet that she couldn't bear to swallow it all at once.

After eating, she couldn't hold back for a while, and bluntly said: "It's delicious."

Jiang Chengyi ignored her, and after a while he said, "What time do you go to work at night?"

"It's half past five." She took the initiative to clean up the dishes and walked to the kitchen.

Jiang Chengyi glanced at her back lightly.

The heating at home is very high, and she only wears a set of close-fitting home clothes, with long legs and thin waist, and her buttocks are upturned.

He suddenly flashed in his mind how she wore a cheerleading uniform a few years ago, with a white T-shirt and a white pleated skirt. When he saw her, she was sitting on the stand reading a book with her slender, snow-white legs bent.

There were many people on the basketball court walking by, and there were countless irritating and fiery glances around, but none of them belonged to her.

He pretended not to notice her, and while throwing a basketball, he chatted casually with his teammates. When he passed her, she was still reading a book without even looking up.

He glanced over her shoulder at the book in her hand, eh? Comic books, isn't she a master of class six, she actually likes to read comic books.

At this time, his teammate threw the basketball back, and he didn't know if he was out of his mind. He deliberately didn't catch it, let the basketball fall to the ground, and then dribbled into her shoe upper.

Her shoes were also white, washed very cleanly, and when they were touched by a dirty basketball, the uppers became dirty immediately.

She finally put down the book and looked up at him.

As if nothing had happened, he leaned over to catch the ball, his eyes swept across her knees, he was startled, it turned out that a girl's skin can be so delicate and milky.

She was still looking at him, wondering if it was his illusion, he always felt that her eyes were too clear, and he could see through his mind at a glance.

He pretended to look back casually, her attitude was still very indifferent, but under his gaze, her long eyelashes suddenly trembled imperceptibly.

He slowly stood up and said indifferently, "Oh, classmate, I'm sorry."

Ansan District Office

Lao Qin and others gathered at the desk to study the file, and when they saw Jiang Chengyi come in, they quickly said, "Team Jiang, Ding Jing's autopsy report has come out. Like Wang Qianqian, she was first strangled, and then wrapped in waterproof inflatable material by the murderer. in the lake."

Jiang Chengyi pulled out the computer chair and sat down, took the two files, turned to the photos of the scene, and compared them carefully again.

Lao Qin looked at Jiang Chengyi: "Jiang team, how is it, have we approved the report we handed in this morning?"

Jiang Chengyi nodded: "The modus operandi of the two cases has a high degree of overlap, and there is a high possibility of a series of crimes. There will be a meeting in the bureau in the afternoon to discuss."

It wasn't long before Xiao Zhou started working. After hearing this, he scratched his hair: "One is Yanping Lake in the suburbs, and the other is an artificial lake in a park in the city. The murderer seems to like water quite a bit. But that's not right, even if it's a serial murder case. , in order to obliterate the evidence, the murderer hoped that the body would be found later, but the murderer insisted on getting an inflatable material to float the body in the lake, for fear that others would not see it—"

Jiang Chengyi posted the same live photos of the two cases on the display board without speaking.

Lao Qin stared at the photo and approached thoughtfully: "Team Jiang, I remember that before Ding Jing's case came out, you said that Wang Qianqian's body throwing scene had a sense of ritual. If this guess is true, the murderer will do this. What's the purpose?"

Jiang Chengyi recalled the words of the witness who discovered Ding Jing's body that night: the dark lake surface, the white body bag floating in it, and the sight of the fetus floating in the amniotic fluid.

"What the murderer wants to do is still unknown." Jiang Chengyi said, "But you should remember that after killing Wang Qianqian on the 28th, the murderer also sent a text message to his colleagues in Wang Qianqian's tone on the 29th."

"Yes." Lao Qin nodded, "It's like buying time."

After stopping for a few seconds, he tried to analyze: "If the murderer doesn't do this, Wang Qianqian's colleagues or family members will soon suspect that Wang Qianqian has an accident, and then call the police or look for people everywhere. In this way, the murderer may not be able to follow his own rules. The idea is to set up an ideal throwing scene. Assuming that there is a sense of ritual, the murderer would rather take the risk of revealing his feet, and must use this method to delay time. It can be seen that for the murderer, the sense of ritual is very important. , Looking at the entire crime process, can the idealized corpse dumping scene even be said to be an indispensable part?"

"Huh." Another police officer took a sip of hot water, "This person is really perverted."

"And have you noticed?" Jiang Chengyi wrote the time points of the two cases on the whiteboard with a marker, and threw the pen back to the desk, "From the time Ding Jing went out in the morning - was murdered - the body was found, I only used a total of Twenty-two hours, the whole crime was completed in one go. Looking at the Wang Qianqian case again, Wang Qianqian was killed on the 28th, and his body was thrown on the 29th. In order to fake the illusion that Wang Qianqian was still alive, the murderer had to imitate her tone and send text messages, although in the end There are no flaws left, but from the perspective of the time dimension of the whole case, the murderer lacks a sense of fluency."

"Team Jiang, you mean—" Xiao Zhouruo realized something.

"From Wang Qianqian to Ding Jing, the murderer's modus operandi has become more and more skilled."

The office was silent for a moment, and Lao Qin spat: "Damn, I can't understand these perverted thoughts. By the way, Team Jiang, you asked me to contact Dr. Yu in the morning. I called, but Dr. Yu went to City B a few days ago. Lectures, it will take two days to come back."

"Dr. Yu?" Xiao Zhou's eyes lit up, "Yu Zheng? That famous criminal psychology expert? Will he handle the case with us?"

Old Qin glanced at him: "Look how excited you are. Team Jiang said that there are many doubts in these cases, and criminal psychologists are needed to help solve the case, so I made a report together in the morning."

At this time, a few more people came in, and one of them handed a folder to Jiang Chengyi as soon as he approached: "Jiang team, that bag was turned out from the trash can of Wang Qianqian's house, you asked us to send it to the forensic doctor a few days ago. I went to check, and the forensic doctor restored some of the damaged items, after sorting and analyzing, I just made a report."

Jiang Chengyi turned the pages one by one.

Most of them are daily items, miscellaneous and trivial. There are about a dozen supermarket shopping receipts, several tubes of skin care products that have been used up and discarded, as well as snack packaging, and worn stockings...

When his eyes glanced at one of the photos, his eyes were fixed.

Old Qin came over to take a look and saw that the photo was a sticker whose original color could no longer be seen, a bit like the one that children often play with. Part of the surface of the sticker had been damaged by sewage, but it could be seen that it was in the shape of a butterfly.

Seeing Jiang Chengyi's face getting more and more ugly, Lao Qin wondered, "Team Jiang, did you find anything."

Jiang Chengyi's eyes were still fixed on the photo, and at the same time, he took out something in a disposable fresh-keeping bag from his arms and put it on the information page for comparison.

Lao Qin and Xiao Zhou stared at each other and couldn't help being stunned.

Two things are put together, although one is bright and complete, the other is dim and tattered, but it can still be seen that they are the same sticker.

Jiang Chengyi looked at Lao Qin: "You will take Xiao Zhou and the others to Ding Jing's house to search, in addition to her house, there is also the foreign trade company where she works, the bedroom and the desk, and look for similar stickers. ."

After finishing speaking, called Lu Yan, but there was no answer after a series of calls.

He put on his coat: "I'll go out and meet at the bureau later."
