Han Yan and Ye Chen didn't drive, they came out of Tang's house and walked along Tang Shanshan's normal night run, while observing the surrounding environment. The pen "fun" pavilion www.biquge.info community is very new, the greening is good, but the monitoring facilities have not been installed, only there are two cameras at the entrance of the community. Out of the community to the east, there is an avenue, and there are only a few small storefronts on both sides, restaurants, barber shops, shops, etc., which are not close to each other, and are evacuated in rows.

Han Yan and Ye Chen were not slow, and in less than twenty minutes, they walked to the park, saying that it was a park, but there was no periphery, only a circle of greenery was built, symbolically indicating that the boundaries were different from then on, Ye Chen stood there and sighed: "Such a big ......"

The scope is too large, it is not easy to judge Tang Shanshan's specific route last night, and it is not easy to check the people and vehicles coming and going.

Han Yan glanced around, took her right and walked in: "The victim has the habit of running at night, according to common sense, he will take the main road, there are lights on both sides of the road, and there are many people on the road at about eight o'clock in the evening. ”

"So......" Ye Chen followed him deeper and deeper, "The murderer has a car, what method did he use to trick Tang Shanshan into the car, and even into the car, and take her away." ”

"Well," Han Yan stood still, next to it was a narrow green belt, and under the green belt was the road, such a close distance, it didn't even take a minute to drag Tang Shanshan down, "The victim's parents also said that she is a very enthusiastic person, if there is anything that needs her help......

"She's likely to be fooled," Ye Chen crossed his arms and walked to the side of the street sign to see the park structure clearly, "Let's release the news, even if it's not big, it's likely that someone will notice." ”

"Not now, the news will stimulate the murderer and speed up the process of crime, Chi Xun guesses that the murderer will kill in five days, we still have time," Han Yan walked to her side, frowned and looked at the map, "There are three places where crimes may be committed, we will call up the monitoring of these three roads, and check one car at a time." ”

When Chi Xun received a call from Liang Yu, he had just arrived at the scene where the body was found, the streets were very lively during the day, there were people selling vegetables on the already narrow road, and the crowd was tight enough for one person to pass, and the storefronts on both sides were open such as restaurants, and the boss withdrew the table covered with a layer of oil to scrub the tabletop, and there were some activities at night, at this time, the wooden board closed the door.

Chi Xun's existence is incompatible with here, he is a sunny and clean boy, and his sudden appearance has caused a lot of discussion and speculation, and the woman in the shampoo room leans her shoulders against the door panel and smiles at him. Ji Xun was not embarrassed, and smiled back at people gently.

"Chi Xun, I went to Lu Yan's school, he didn't go to class today, and then I came to his house, his mother took him alone, he is a doctor, and he happened to be at home today. Lu Yan told his mother that he went to play with the classmate last night, but we just called the classmate's house and he lied. ”

"Hmm," Chi Xun replied, crouching down to inspect a drag mark on the ground, "and?" ”

"I entered his room," Liang Yu seemed to be at a loss for words, and paused, "There is something you need to see." ”

Chi Xun hung up the phone, and after a while, Liang Yu sent a few photos, he tilted his head slightly to avoid the light, and saw that there were several magazines in the photos, and the pages of the model's swimsuits were scratched several times with a knife, and the last photo was a page of the diary, with red handwriting: "Cut her neck with a knife, watch the blood gush out, splash on the wall, scarlet hot blood, will also be poured on my body, and then I will pull out her blood veins......"

The writing is oblique and messy, and the writer is emotionally unstable.

"Liang Yu, be sure to find him."

"Don't worry."

Chi Xun looked at the photo for a while, put the phone back in his pocket, took out the glove belt, and collected the marks left by friction on the ground.

As soon as Han Yan and Ye Chen returned to the police station, they were stopped by the police on duty in the hall: "Officer Ye! ”

"Huh?" The two turned around at the same time, and the little policeman found that Han Yan was also there, and he was sitting, so he quickly stood up straight, "Captain Han!" ”

"Well," Han Yan replied indifferently, "What's the matter?" ”

"Someone sent a letter to you two groups in the morning." The little policeman took out the letters from the drawer, snow-white envelopes, on which nothing was written.

"Who?" Han Yan took the letter, held it up and shone it into the sun, and saw that there was only a thin piece of paper inside.

"Hmm...... It's just a child, six or seven years old, who sent him. ”

"Okay." Han Yan nodded to the person and took Ye Chen away. The little policeman stood in place, feeling sweat running down his back.

When I went, they all said that Captain Han of the second group was the living Hades, and this was an unsmiling expression...... Hey, how do the people in the second group usually live, I really feel sorry for my Goddess Ye.

Han Yan entered the door and pulled out the paper, and saw that there was only one line on it: They have no chance.

"They don't have a chance to ......?" Ye Chen read out the words on the paper, looking at the person in confusion, "What does this mean?" ”

"Leave it to Chi Xun." Han Yan separated the letter paper from the envelope, handed it to Tang Duge to check his fingerprints, and asked people, "Xingfan, have you found anything?" ”

Shen Xingfan only has one thing left at hand to investigate a similar homicide, but it is not easy to investigate, and there is no complete integrated information base, many times she needs to go through it one by one, she has been filled with various corpses for two days, and at this time her face is painful: "Boss, I think I may not be really suitable for this job, I need to go to the playground for a day to see Donald Duck Mickey Mouse and Snow White." ”

As he spoke, the computer suddenly sounded, "I'll go," Shen Xingfan sat up straight suddenly, "Found it." ”

"The body found in the Chengbei Development Zone two years ago, female, identity unknown." She gave a brief and quick introduction.

"Unknown?" Han Yan walked over, Tang Duge was holding an envelope to check his fingerprints, and when he heard the news here, he also walked over and leaned down to look at the specific forensic examination.

"Well, the modus operandi is similar to this one." Tang Duge quickly came to a conclusion.

"So that's also the person he killed......? It's been two years, and he's still at large......" Shen Xingfan couldn't tell whether he was angry or incredulous, he couldn't help but sigh, and then explained Han Yan's question, "Well, the identity is unknown, and the murderer has not been investigated in the case, and it is still an unsolved case, but two years ago, the databases of different provinces and cities have not been fully connected, and I can investigate again." ”

Han Yan nodded: "Transfer the case materials, and I'll go through the formalities." ”

At the same time, Chi Xun, who had just gotten in the car and was about to return to the police station, received a phone call. He was in contact with several psychiatric clinics, and the person who called was the attending physician at one of them.

"Dr. Chi, I have a person here, who said he wants to see you."

Chi Xun raised his chin slightly: "Lu Yan? ”
