The landlord provided the contact information of the victim's friend, Su Ping added a few questions, and seeing that he couldn't provide many more valuable clues, he ended the inquiry, and the landlord didn't bother to go back, so he simply went to the top floor to rest.

Brother Song took out his mobile phone and asked, "Team Su, do you want to call him now?" ”

"It's almost two o'clock, Ming'er...... Come on when it's dawn. Su Ping shook his head: "That's it for tonight, when Xiaochai and Lao Yan finish surveying the scene, they will close the team first, and the visit will be officially launched at dawn." As for the families of the deceased, they also talked about it early in the morning, at least let them sleep well.

In addition, you quit the special operation team first, and I will arrange for a relatively idle colleague to replace you, and your energy will be focused on this murder case, and if you can, try to solve the case as soon as possible. ”

"Okay." Brother Song's jaw.

After thinking about it, Su Ping said again: "Notice, eight ...... in the morning Nine o'clock, nine o'clock, come to my office, have a short meeting, and report the situation.

If you can, persuade Xiaochai, don't fight so hard, what about being pregnant, go to the police at night, do you want the child? I said she didn't listen, you try to ......"

"Huh?" Qi Yuan was stunned: "Sister Chai, she's pregnant?" ”

"You don't know?" Su Ping looked at him in surprise: "Aren't you her cousin?" I didn't even know about such a big thing? ”

Qi Yuan scratched his head: "I don't know, I guess she didn't tell her family, otherwise my parents would definitely have to tell me and let me help take care of it, after all, I am a relative like her in Yuqiao, and she is the same." ”

"I've been pregnant for almost two months." Su Ping understood, nodded, and said: "No matter what reason she is in, she doesn't say anything to her family, but she is pregnant with a child, she will definitely not work like this, find a way to persuade her, if it doesn't work, tell your parents, and let the elders in the family watch it."

Isn't this nonsense, just do some daily easy work, how can you stand staying up with us day and night? ”

"Got it." Qi Yuan nodded lightly and said, "I'll persuade her, if it doesn't work, let my parents persuade her." ”

"Hmm."

……

Early in the morning, at around 8:50, Qi Yuan, Chai Ningning, Yan Zhongxin and others came to Su Ping's office to gather.

Su Ping looked up at Chai Ningning and said, "Xiao Chai, after the meeting, hand over the work, and go to rest." ”

"How can this be ......?"

"I just said yes." Su Ping glanced at her: "You are not the only one who carries the trace examination department, such a large department, and you can't carry it alone, you have to believe in your subordinates, believe in your colleagues, even if you are not staring, they can do a good job, not much worse than you." ”

Chai Ningning pursed her lips and finally nodded slightly.

"What did you find?"

Yan Zhongxin pushed his glasses and said: "The autopsy results are out, and the autopsy has not been carried out yet, because after investigation, it is not necessary to do so, so I used a biopsy needle to take some samples for identification."

Well, the deceased Zhao Guangbo, 24 years old this year, has no signs of illness and past medical history, and has no signs of poisoning, and died from mechanical injuries, and the time of death was between 5 pm and 5:30 pm last night.

When committing a crime alone, the murder weapon was found at the scene, a double-edged short dagger still inserted in the deceased's chest, and no palm prints or fingerprints were found on the handle of the dagger, and the murderer should have carefully cleaned the dagger before committing the crime, and wore gloves when committing the crime.

In addition, the dagger itself is not bladed, but the handle is obviously worn, and some parts even form a pulp, it is estimated that it has been bought for a certain time, and it is often played. However, it is not possible to determine whether the dagger is the deceased or the perpetrator.

That's pretty much it, is there anything else to ask? ”

Su Ping shook his head and looked at Chai Ningning.

"A group of suspicious footprints were extracted from the scene, which were identified as basketball shoe prints, and the sole pattern was more seriously worn," Chai Ningning said.

In terms of gait analysis, there is nothing abnormal, and the height is presumed to be similar to that of the deceased, but the burglar who was caught has provided clues that the suspect's physical characteristics are close to the deceased, so it is not of great value to investigate in this regard.

On the other hand, no other biological evidence has been found at the scene, so let's go back and ask someone to do a detailed investigation first, first collect all the hair strands and other objects at the scene, and then sweep them with a vacuum cleaner to carry out detailed separation and identification of the obtained substances, which may be able to make a breakthrough.

But it's too much work, and you won't be able to do it for a while.

In addition, there is a discovery - we found a scabbard in the trash can downstairs, presumably with the dagger is matched, but unfortunately no fingerprints were found on it, and further detailed investigation is currently being done, hoping to find it. ”

Su Ping nodded: "It's hard work, let's go down and rest first, and leave the rest of the work to other colleagues." ”

Chai Ningning didn't bother again, only nodded and said, "Call me if you need it." ”

"Hmm."

"Then I'll go rest for a while." Yan Zhongxin stretched his waist: "I have been busy all night, but I am tired." ”

"Go ahead."

The two walked out of Su Ping's office side by side.

Watching the two of them leave, Su Ping's eyes fell on Qi Yuan again: "Have you persuaded Xiao Chai?" ”

"Hmm." Qi Yuan bowed: "At about three o'clock in the morning, I joined forces with other colleagues in the trace examination department to ask Sister Chai to rest, and the analysis work was mainly done by other people." However, at half-past seven, she still woke up......"

"It's good to rest." Su Ping snorted and said, "Arrange your tasks."

First of all, the technical team analyzed the deceased's mobile phone, and determined a list of relatives, friends, and classmates by studying the call records and chat records of social software.

At present, the person who has a relatively close relationship with the deceased is his college roommate and colleague in the tobacco factory, and it is also the person who the landlord has raised, named Shi Kunsen, who is the same age as him.

In addition, it is currently confirmed that there are still five people who still live in Yuqiao and still have contacts with the deceased, named Zhou Antai, Liu Jianzhou, Xu Dekang, Chen Wenyou and Chen Shao.

Song, Xiao Qi, Shi Kunsen, and Zhou Antai will be handed over to you for a visit; Lao Hai and Xiao Fang, you two are in charge of Liu Jianzhou, Xu Dekang and Chen Wenyou; There is only one Chen Shao left, he lives far away, in the southern urban area, it takes two hours to go back and forth, Xiao Wang, Ah Xian, you two are responsible.

We will send you the addresses and contact information of these people separately. ”

Seeing that everyone nodded, Su Ping said again: "Repeat, your first priority is to find out the interpersonal relationship of the deceased through these six people, find out who is close to him, whether there has been a conflict with whom, and at the regular meeting tonight, you have to hand in a detailed relationship chart."

As for the parents of the deceased, I will inform them to come. ”
