"Husband, husband, why can't you think about it like this...... You don't care about me......"

"Shufen, hurry up..."

Lang Zhijiao and the others were about to return to the team, when a woman broke into the door and sobbed. She had black hair and a shawl, and was dressed in a rich attire, and she knelt in front of the door. A strong, short-haired man bent over and pulled the woman hard with both hands, persuading.

"Who are these two ......," Lang Zhijiao asked.

"She is Wang Shufen, the wife of the deceased. This man is the informant, the neighbor and colleague of the deceased, Lu Hai. Cui Tianhui replied.

"Take the two of them back to the team and make a new record." Lang Zhijiao looked at the two, thought about something, and continued: "Bring back the relevant physical evidence I said, and make a detailed identification of the deadly poison on the corpse." In addition, do a good job of environmental blockade on the site. Call up the surveillance video of the community to check if there are any suspicious people entering or leaving. ”

"Team Lang, the property equipment in this community is very simple, and the few cameras are broken."

"Then go ask the doorman and see if you find anything."

After saying that, everyone began to divide the labor, moved the physical evidence and corpses downstairs, and went back to the detachment.

September 20, 2009, around 10 a.m.

Lang Zhijiao led the team back to the detachment office, and under Zhao Yunsheng's repeated persuasion, he held a simple meeting in the conference room.

Lang Zhijiao's meeting can also be regarded as Zhao Yunsheng's retirement and resignation public meeting. After the meeting, he was going to invite the people in the team to dinner, saying that it was for Lang Zhijiao, but he politely refused. And Zhao Yunsheng packed up his personal belongings and prepared to leave.

"Xiaolang, I didn't say you. Seeing the wrinkles on my face, I was at least ten years older than my old classmates who came with me. Alas...... It's all about. You should learn to combine work and rest. ”

Zhao Yunsheng was still complaining that Lang Zhijiao did not accept his meal.

"Okay, Captain Zhao is right, I'll pay attention. In the future, I will not be busy, I will invite this meal. ”

Lang Zhijiao smiled awkwardly, then raised the scarred eyebrows, signaling that he would make up for the meal later.

Here is a simple farewell, and the people in the conference room exploded.

"It's really over, the new official takes office, three fires. What a big meal, it's gone...... Alas......"

"That's it, Sister Xiaoyun's child is still waiting to replenish her body...... However, our Lang team is really young and handsome......"

"Wan'er, am I not handsome? On weekdays, I am so good to you that I actually praise a newcomer. Hmph......"

"This Lang team is not simple, it is said that he is still a doctor! After only two years in the field, he was promoted. ”

"yes, I've heard that, too. I just don't know if it will work to solve the case...... Brother Biao, what do you think? ”

"I was just wondering why he thought he had killed him. It was clearly a suicide case, but when he said that, I really believed it. After so many years, it has really become an occupational disease......"

……

"Ahem"

A cough sounded, Lang Zhijiao walked into the conference room, and several people who were talking quickly closed their mouths and sat down quietly.

Lang Zhijiao's face was flat, he looked at the clock on the wall, and began to assign tasks.

"It's 10:45 a.m., and you're probably going to be busy for a while. Yang Xiaoyun and Qin Wan hurried to make a death report. Toxicology identification, including the internal organs of the deceased, and in vitro vomit analysis is required. The fingerprints collected were compared with those of the deceased and his relatives and neighbours. In addition, take a sample of the beans in that bottle and analyze the contents. Speaking of this, Lang Zhijiao's gaze shifted to the side and continued: "Brother Biao, you and Xiao Cui go to the school where the deceased worked to find out the situation. By the way, including that Lu Hai. After the incident, contact the relevant departments again to check the financial status of the deceased and his wife Wang Shufen, including Lu Hai. Xiaobian, you and I will stay in the team and make a detailed record for Wang Shufen and Lu Hai. ”

"Yes! Team Lang! After listening, several people said in unison.

"Okay, everyone, hurry up and go your separate ways. That one...... When that's done, I'll treat you all to a meal. Location, you choose! ”

Lang Zhijiao clapped his hands and motioned for everyone to hurry up. However, seeing that everyone's interest was not so high, he naturally turned to invite everyone to dinner. As he spoke, he twitched the scarred eyebrows.

"Eat roast goose!"

"Team Lang, long live!"

……

"Okay, if you want to have lunch early, just hurry up."

After speaking, the big guys laughed and turned serious, and ran out one after another.

September 20th, 2009, at 11:05 a.m.

Panyun District No. 3 Middle School, Principal's Office.

"Principal Zhang, we are here this time to inquire about the personal situation of Wu Jianguo, a chemistry teacher, and Lu Hai, a physical education teacher."

The person who spoke was Liu Hanbiao, he showed his ID, don't ask directly.

"Comrade policeman, I also deeply regret the death of Wu Jianguo. After all, he is an excellent teacher in our school, and he also has a graduating class. In chemistry, he taught the best. Many students who were poor in science were because they were too poor in chemistry and their overall scores were lowered, but after he substituted for his classmates, his chemistry scores skyrocketed. The classes he taught were also among the best in school. That one...... Comrade policeman, how did he die in the future? ”

Principal Zhang sighed and asked secretly.

"Principal Zhang, the forensic examination has not come out for the time being. You should know that these are confidential. So...... Let's talk a little bit about these two people. What is the intersection between the two of them, and how are they usually becoming? Liu Hanbiao said.

"Well... Don't ask what you shouldn't. The two of them usually commute to work together, because they live in the same community. The disciplines are different, and naturally there is no intersection in school. As for their personalities, I didn't have much contact with them when I was the principal, and I only heard about them. Wu Jianguo is quite honest and committed to school teaching. No, the graduating class started in mid-August, and he came back from his hometown in the south very early. In addition to teaching chemistry well, he is also very good at literature and art. I often show my face at some activities in our school, write poems, sing songs, etc. Lu Hai, I just have more contact before and after the school sports meeting, and it is only necessary for some work. However, looking at the school sports meeting organized by him, it was quite orderly, and every time it was held, it went smoothly. He usually likes to laugh, and everyone likes to say a few words to him. Dressed up, he is usually very fashionable, and he is a well-known handsome guy in our school. I just don't know why I'm so old and haven't gotten married. Alas...... We can't guess the thoughts of young people. ”

Principal Zhang sighed in his words, and said everything he knew and what he thought.

"That...... Principal Zhang, that's it. Can you contact the head teacher of Wu Jianguo's class, we want to know more about the specific situation. Also, who are the people in the school who have an intersection with Lu Hai, please help contact them. ”

……

After about 20 minutes, Principal Zhang led the two to the office. One is the head teacher of the class led by Wu Jianguo, and the other is the teacher of the school's dance team. After inquiry, it was learned that the two were very familiar with Wu Jianguo, and the head teacher naturally had more contact with Wu Jianguo, and the female dance teacher also had a lot of contact with Wu Jianguo during some dance and music choreography because of the needs of some activities in the school. And the only one who has an intersection with Lu Hai is the female dance teacher, who is in the same office because of physical education teaching.

While Liu Hanbiao was talking to the two, Cui Tianhui was taking notes. I was busy for more than half an hour, and I did get some more specific information about the two people.

"Comrade policeman, is there anything else you need to ask? If not, we'll go back to the dormitory to rest, and there will be classes in the afternoon. ”

It was the female dance teacher who spoke, named Fang Ya. During the questioning, she always put on a pretended smile, perhaps because she was a little uncomfortable facing the police.

"Not for the time being. We will contact you again if necessary. Thank you both. ”

Liu Hanbiao said, and Principal Zhang also sent the two out of the door.

"Principal Zhang, do you have a teacher's dormitory in your school? Why didn't Wu Jianguo and Lu Hai live in school? Wouldn't it be more convenient to teach this way? ”

When Principal Zhang returned to the house, Cui Tianhui immediately asked a series of questions.

"Oh, yes. The school arranges accommodation for teachers, and some in-service teachers will move out for personal reasons. Some are married, and some are at ease. In this way, the school will also give them some housing allowance. Lu Hai is a chic young man, so he should also want to be free, after all, there are many school rules. And Wu Jianguo, I heard that in his spare time, he worked part-time as a tutor. There are many students in the community, and he should also be convenient. The specific reasons are not clear. ”

Principal Zhang answered truthfully, not in a hurry, he has long been accustomed to this phenomenon. After all, he can't understand what people are thinking now.

"That's right...... Then, Principal Zhang, we'll go back first. I'm sorry for you this time, if you need ......."

"If you need it, just ask. I don't usually have much to do. ”

At the end of the inquiry, Liu Hanbiao and the others did not make any stops and returned to the team directly.

……

At the same time, Lang Zhijiao was making inquiries for Wang Shufen and Lu Hai, and he was taking notes on the side.

"Wang Shufen, how did you learn about your husband's death?" Lang Zhijiao asked.

"It's when I got off the plane in the morning, Haizi called me."

Wang Shufen didn't sobbed before, and she had already accepted the fact that her husband was dead. Her hair was a little messy and her complexion was flat.

"How often do you usually come to Panyun City from the south? Why did you come here this time? Lang Zhijiao asked.

"I usually only come here twice a year. At the beginning of spring, it comes up once. At the beginning of spring, the spring here is very beautiful, and my husband will take me to watch the school sports meeting organized by Haizi to recall the breath of youth. Also, I came here once in late September. That is, this time, for the wedding anniversary. Every year on this day, we get together. But this time, ......" said, Wang Shufen cried again.

"That, the Haizi in your mouth is Lu Hai, right? How long have you known each other? Familiar, right? Lang Zhijiao was suspicious.

"That...... No... No, only my husband is familiar with him, and I am with the sea... Lu Hai has only met a few times, and he is not very familiar. ”

When Wang Shufen heard Lang Zhijiao's question, she suddenly panicked, shook her head slightly, and her words were a little unreasonable.

Seeing this, Lang Zhijiao's scarred eyebrows were lowered, and he came to the bridge of his upper nose, as if he was thinking about something, and then said, "Well, did you talk to your husband on the phone before you got on the plane last night?" What was discussed? Did you notice anything unusual about him? ”

"Yesterday afternoon on the phone, nothing was discussed. He...... It's just that I miss me very much, and I was very depressed at that time. I comforted him for a long time......"

After speaking, Wang Shufen didn't know why, she lowered her head again, maybe it was because she mentioned the dead Wu Jianguo, she was sad again.

Lang Zhijiao calmed down a little, asked a few more questions, and called Lu Hai to the office. During this period, it was just a few ordinary questions, and Lu Hai didn't think about it, and explained them one by one.

After that, Lu Hai went out of the door and saw Wang Shufen, a seemingly ordinary meeting. And Lang Zhijiao noticed a look when the two met, a brief look. Suddenly, his scarred eyebrows slowly raised again.

At this moment, the autopsy report, poison identification, interrogation of relevant people, and comparison of fingerprints have all been completed one by one. Several people were on their way to the conference room.
