Towards the end of the year, the streets of Huajiang City became lively.

Chen Nian and Fang Jinyu stood at the door of the city bureau, their faces red from the cold. Ten minutes later, Zhou Kejian came out of the building, followed by Cai Yao, who was trotting all the way.

"Why is she here?" Chen Nian asked.

"If you don't have to be clamoring to go out on duty, I can't fix it." Da Zhou said.

Chen Nian was a little displeased: "It's not a murder scene, a forensic doctor, what kind of field work?" ”

"I'm going to go. What happened to the medical examiner? Cai Yao held her chest high, "Who stipulates that female forensic doctors can't investigate cases?" Or is it not beautiful enough to investigate the case? ”

When Cai Yao said the second half, she glanced at Fang Jinyu with her afterglow.

Fang Jinyu didn't seem to take it seriously: "Let's go, let's go, let's get in the car, it's a cold day......"

Chen Nian was helpless, and decisively gave the order of the group: "Da Zhou, you take Cai Yao to the No. 2 Middle School, and Jinyu and I will go to Forestry High School, and report the situation at any time." Seeing that Cai Yao wanted to speak out against it, he then said, "It's so decided, let's go." ”

The jeep has been drying in front of the door for a long time, and after getting into the car, it will be refueled and left. Fang Jinyu, who was sitting in the passenger seat, met him in the rearview mirror, but did not speak. When the car got on the main road, the two suddenly said to each other at the same time:

"Is it still cold?"

Although Zhou Kejian and Cai Yao set off late, due to the slightly closer distance, their group was the first to arrive at Huajiang No. 2 Middle School.

Da Zhou found the teaching director, explained his intentions, and handed over the photos that Gao Fang had processed overnight.

The dean was a greasy middle-aged man with his hair combed on his back. He took the photo in the posture of holding a cigarette and took a closer look: "That's right, this is our school uniform, everyone says it's a bit similar to the work clothes of the power supply bureau, hehe......"

Cai Yao didn't expect that the first time she went out to the field would go so smoothly, and she glanced at Da Zhou overjoyed. Da Zhou Hui looked at him with a determined look. Cai Yao asked the dean of education quickly: "Then can you tell that this is a school uniform for what grade?" ”

"A freshman in high school, yes, a freshman in high school."

"Are you sure?"

"Sure. The school uniform of the first year of high school is a three-collar collar, which is not the same as that of the second and third years of high school. ”

"Can you tell who this student is?"

The dean of students compared the picture farther and then closer, and finally said affirmatively, "I can't see it, I don't think I've seen this student." ”

"If you look closely, maybe the photo is not very clear, and it is difficult to identify for a while."

The teaching director laughed: "No need, don't look at me just transferred this semester, but the entire Huajiang No. 2 Middle School has 3 year groups, 14 classes, and 689 children, all of which are in my head......"

It's cold and windy in the suburbs.

On the Forestry High School side, Chen Nian and Fang Jinyu also launched an investigation, but they did not alarm the school, but secretly observed themselves outside the school when the students gathered in the morning to enter the school.

Forestry High School is located in the northernmost part of Huajiang City, which is a mountainous school with a semi-boarding system. The school is not large, but the staff is relatively mixed. Nearly one-third of the teachers and students were transferred or transferred from other districts and counties.

At around 7:20 a.m., the school security guard came out and closed the school gate.

Fang Jinyu reminded Chen Nian: "Hey, Lao Chen, don't you go in yet?" ”

"Wait." Chen Nian glanced at his phone.

A few more minutes passed.

A few more late students went in sporadically.

Fang Jinyu wanted to say something again, but at this time, Chen Nian's mobile phone rang.

"Hey, Da Zhou, how are you doing over there?"

"The school uniform is confirmed, it is the first year of the second middle school and high school, but the person is still not sure." Fang Jinyu heard Da Zhou say on the phone.

"Da Zhou, you ...... like this," Chen Nian adjusted his sitting posture, "You ask the school again, if there are any students who transfer to other schools in the middle of their first year of high school, and if so, ask for a list." ”

Chen Nian put down his phone and found that Fang Jinyu was smiling at him strangely.

"Teacher Fang, why do you think of me like this?" Chen Nian said.

"Lao Chen, Captain Chen, it turns out that you are selling this medicine in your gourd! …… Pretend to be with me, I'm not a new ......."

"Yes, yes...... How dare you pretend to be in front of Teacher Fang, Doctor of Psychology, what tricks can't you see? ……”

"Flicker, flicker, flicker...... I said, when did you, Captain Chen, become so ......?"

"What?"

"Contrived!"

"Don't like it?"

Fang Jinyu pulled her long hair to the side and said word by word: "No, happy, happy." ”

Chen Nian looked at Fang Jinyu's perfect side face, and was speechless for a while: "That...... I change, I change...... If Teacher Fang doesn't like it, it must be changed, it must be changed......"

"That's pretty much it."

"That's not right, Teacher Fang," Chen Nian saw that he had saved the day, and deliberately asked, "Are you jealous?" ”

"Joke, what kind of jealousy do I eat, can anyone make me jealous?"

“……”

Before he could say the old words, the phone suddenly rang again. It was Da Zhou who sent the list of transfer personnel.

Fang Jinyu came over to watch it together.

Chen Nian swiped up on the screen of his phone, and Fang Jinyu read the words on the list in his heart. Suddenly, a line of small words shining with dazzling light made her eyes tremble—Zhang Xiaowu.

Office of the Serious Crime Unit.

Chen Nian brought a cup of hot coffee to Fang Jinyu. Fang Jinyu raised her head and looked at him with a puzzled expression.

"I said it, I'll talk about it when you're done." Chen Nian's voice when he said this was like a ray of warm sun thrown in from the window at this moment, both comfortable and dependent.

"I'm still a little unsure...... Fang Jinyu said, flashing the pair of grass-stained sneakers he wore when he met Yao Xinwu in the corridor at midnight, and flashing the shy but cold eyes that repeatedly hid behind Yao Yingchun......

Chen Nian looked at Fang Jinyu with firm eyes: "Say your suspicions, and let's find the answer together." ”

One second.

Five seconds.

Ten seconds.

"Okay!" Fang Jinyu finally unloaded the burden in her heart.

The bell has struck 11 times.

The Criminal Investigation Team held a comprehensive case analysis meeting. In addition to the members of the serious crime team, the director of the bureau, Qian Weiming, the captain of the second criminal investigation team, Li Zhaohua, and other relevant personnel all participated.

At the beginning of the meeting, Li Zhaohua, the second captain, first gave the latest clues that the second team had mastered: on the morning of December 20, some people reported that someone in the family area of the Municipal Broadcasting Bureau had attempted to break into the house. According to the information provided by the informant, the suspect was wearing the uniform of the No. 2 Middle School, with a burly figure and an old appearance, and a three-bar armband on his left arm.

Combined with all the clues, the meeting clearly stated: 1. Many QJ homicide cases in the city in the past month were committed by one person; 2. The nature of the case is heinous, murder is the means, and rape is the goal; 3. The criminal is meticulous in his thinking, premeditated to blame others, and misleads the police to solve the case; 4. Convicts should have conditions such as withdrawn personalities, high IQs, longing for women, and being pessimistic and dissatisfied with society; 5. Be between the ages of 16 and 22, be about 1.75 meters tall, and have a mature face, and the possibility of juvenile crimes cannot be ruled out.

Chen Nian ordered Zhou Kejian to take out the school uniform borrowed from Huajiang No. 2 Middle School for comparison, and it was very similar to the uniform of the business staff of the Power Supply Bureau, but the color was slightly lighter.

Subsequently, Fang Jinyu said the name of the suspect: "Yao Xinwu, whose real name is Zhang Xiaowu, is now 16 years old, a first-year senior student at Forestry High School, his father died in a car accident when he was 12 years old, and his mother Yao Yingchun took him to live in the northern forest area. Zhang Xiaowu has a withdrawn personality, but his academic performance is good. A year ago, Zhang Xiaowu was suspected of having a dispute with a classmate due to emotional problems at Forestry High School, and almost killed him. So his mother Yao Yingchun took him to the city, and asked someone to transfer to the city No. 2 Middle School to study, and changed his name to Yao Xinwu. Yao Yingchun used to work as a nurse in the forest hospital, and after moving to the city, she stayed at home full-time. ”

After Fang Jinyu finished speaking, Zhou Kejian asked in a private whisper: "How do you know that Zhang Xiaowu is Yao Xinwu's?" ”

Before Fang Jinyu could speak, a police officer came to report: "The residual fingerprint at the bottom of the lipstick at the scene of the Lin Yang crime has been repaired, and after comparison, it has an 83% overlap with Yao Xinwu's fingerprint." ”

"It's time to talk to this high school student." Chen Nian said.
