Zhou Ning raised his hand and pointed to the hand-drawn drawing on the slide.

"Don't worry, leader, look at this picture, the deceased was found in the master bedroom, although all the cabinet doors in the kitchen and the second bedroom are open, but there are no less things that have not been unpacked, and everything in the living room is also deliberately smashed.

According to the analysis of criminal psychology, once the murderer wants to destroy the evidence at the scene, it means that he wants to hide some information, and this information may not be related to the scene.

Based on the available evidence, my judgment is as follows:

There are one or two murderers, and there is a man suspected to be a woman or a thin man, right-handed, an acquaintance who committed the crime, and wore gloves to commit the crime.

The coercion started between 7:30 and 9:30 in the morning, and the time of the deceased's death was close to the time when the police were called, and the murderer had a hatred for Wen Haicheng, which I think was a vendetta case disguised as a state of robbery. ”

"Gone?"

Zhou Ning nodded.

"The fingerprints on the murder weapon, in addition to the two glove fingerprints, six complete fingerprints were found on this one, seven incomplete fingerprints, there were the deceased and the deceased's wife, and two incomplete fingerprints, which were not found in the fingerprint database, but the fingerprints were covered with latex paint, which I think were left by the previous workers.

Now there is so much information that can be obtained, the inspection report needs to come out early tomorrow morning, as for the footprints and movement tracks, we will compare in detail after we go back, the workload is very large, and it can be completed tomorrow at the earliest.

However, in order to better draw the movement map, I need the shoe prints and fingerprints of the policeman, Zhang Xin, the deceased's son and the deceased's mother, and the deceased's laptop is with me, and the deceased's QQ number is logged on it.

You can let the technical department, check the management I remember that there is a correlation number, the mobile phone was smashed, this is to hope that the information in the mobile phone will not be leaked, the person who smashed the mobile phone, may not know that even if the mobile phone is smashed, you can get the information inside, of course, it may be too late to deal with it. ”

Xu Dayuan looked at Liu Yongxin.

"Forensic Doctor Liu, this is the opinion given by your forensic office?"

Zhou Ning looked at Liu Yongxin with some concern, these summaries were written by him in the car, and he did not communicate with Liu Yongxin, but Liu Yongxin glanced at them just now.

"Xiao Zhou's opinion is my opinion, the computer can let the technical department take a look first, maybe there are some discoveries."

Sun Ju beside Xu Dayuan smiled, took out his mobile phone, dialed a number, and gave a few instructions before hanging up the phone.

"The people from the technical department, come over in a while, the computer and two mobile phones, let them recover, you just send someone to dock."

Xu Dayuan nodded and looked at Da Zhao.

Zhao Xinli was in charge of docking, and the project meeting was held here, and He Chunyang led a team to continue to investigate the social relationship between Wen Haicheng and Zhang Xin, especially their design institute is the focus, and the fingerprints and footprints are collected and sent to the forensic office as soon as possible.

Liu Changhai took people to the kindergarten of the deceased's children, checked the monitoring, asked the teacher, what time Zhang Xin was going to send the children, when to leave, and the time with the community guard, and all the information will be summarized at ten o'clock tomorrow and the meeting will be dismissed! ”

With an order, everyone left, Zhou Ning stood up and was about to leave, Xu Dayuan coughed and waved his hand at Zhou Ning.

"Sun Ju has something to ask you."

Zhou Ning stopped his movements and handed the autopsy report to Liu Yongxin, who gave him a reassuring look.

"Xiao Zhou, I heard Xu Dayuan say, the software project you worked on with Qindao University is going very well, right?"

Zhou Ning nodded, in fact, he hadn't been to Qindao University these days, but just communicated with Dr. Lu, in addition to the software development work, it seems that experts from medical schools and major famous universities are being hired to prepare for the establishment of a forensic college, and not only undergraduates, it seems that they will directly start the enrollment of masters and doctors.

"Now that the first basic data collection has been completed, the programming of AI technology is being carried out, and after completing this step, the secondary data collection can be started, in which AI technology can independently record relevant data, analyze and enter it, and fill in the database content."

Zhou Ning said it decently, after all, he didn't know what this Sun Ju meant by asking like this.

Sun Ju nodded, the smile on his face undiminished.

"Very good, I didn't expect our Qidong Branch to produce such talents, but your own work is also very busy, and the burden on the shoulders of young people is not light, so you have to take it well, by the way, I heard, you want to be transferred to the forensic office of the Municipal Bureau?"

Zhou Ning was stunned, his face full of doubts.

"I haven't heard, when did it happen?"

Xu Dayuan raised his head and laughed, and leaned in front of Sun Ju.

"Why is the leader too worried, I'll just say that you think too much, this kid was personally picked by me, if he has any plans, how can he not tell me, you hurry up and help us coordinate the affairs of the technical department, you don't have to worry about this."

Sun Ju coughed twice and glared at Xu Dayuan.

"Don't call the leader to be polite, it's okay to know that your team is not distracted, Lao Liu will retire immediately, if Xiao Zhou leaves, won't he sing an empty city plan here."

Xu Dayuan waved his hand.

"Thinking too much, oh who said that you have to go to the city bureau to engage in scientific research, Xiao Zhou has been working for half a year, I know this kid very well, he is a working person.

I won't lie to him, in his eyes, engaging in scientific research is a matter of picking grass and beating rabbits by the way, if he specifically wants to do this, why go to the city bureau, wouldn't it be better to go to Qindao University?

Besides, if the leader wants to keep people, just say it with red lips and white teeth, there is no actual at all, and there is no sincerity when you look at it, if you really want to keep people, then apply for treatment, which is a real benefit. ”

Sun Ju was stunned, he didn't expect Xu Dayuan to be treated like this, and nodded vigorously after pondering for a moment.

"You're right, if you want to retain people, we also have to have a mechanism, go back and I'll reflect with the leader, the salary can't be changed, but the specific post allowance can be adjusted appropriately."

Zhou Ning pursed his lips, he didn't know what to say for a while, it seemed that the matter discussed by the two leaders was related to him, but it didn't matter much, but he could make more money, who would object to this, just listen honestly.

Sun Ju stood up and raised his hand to pat Zhou Ning on the shoulder.

"Okay, I'm here to disturb the progress of your investigation, you are busy and I'll coordinate other things, or that sentence is the biggest case in the world, don't drop the chain for me in key places, and I'll go to the city bureau to have a hard waist."

Xu Dayuan accompanied the smiling face, and also stood up, sent Sun Ju out of the door, and when he saw that the person was gone, Xu Dayuan rubbed his cheeks.

"Alright, let's get busy."

"Thank you, Xu Da."

Xu Dayuan waved his hand.

"So much nonsense, by the way, that Zhang Xinren hasn't woken up yet?"

As soon as he said this, Zhou Ning stopped.

"Before my autopsy, I went to the emergency department first, her vital signs were very good, the director of the emergency department said that she should be able to wake up, but there was no response, I checked the injuries on her body, in addition to those cuts, stabs, and blow wounds, Zhang Xin had a fist-sized bruise on her abdomen, which had begun to dissipate, which should have been caused two or three days ago."

Xu Dayuan was stunned.

"You didn't say it just now, do you suspect that the deceased had raped Zhang Xin?"

Zhou Ning shook his head.

"I'm not sure if it was caused by the deceased, I'm just stating when this bruise happened, and I'll compare it later, but the investigation has become more and more confusing, after all, there are many things in the evidence that can't be explained."

Xu Dayuan patted Zhou Ning's shoulder, he couldn't describe such a subordinate as satisfied.

"Don't be sad, I remember you said that where there is contact, there must be traces, and if you don't find it, it doesn't mean that there are no traces, let's look for it slowly."

Zhou Ning smiled.

"Then I'm going to get busy."

Xu Dayuan waved his hand, Zhou Ning went back to the forensic office, and as soon as he entered the door, he saw Da Zhao leading two people to sit opposite Zhou Ning, tinkering with the computer, no need to ask if this was the person sent by the technical department to support.

Liu Yongxin looked at Zhou Ning, Zhou Ning hurriedly walked over, and briefly said the attitude that Sun Ju had just revealed, Liu Yongxin frowned slightly.

"There is no wind and no waves, this is what someone in the sub-bureau knows, but I remember you said that when you went to the development conference of Qindao University, you saw people from the city bureau, and it seemed that they were still making trouble?"

Zhou Ning nodded, in fact, what he was most worried about was this, there was a master here, even if the master retired, he could get guidance by calling and asking.

If he really went to the city bureau, he really couldn't fit in with the two people he saw at Qindao University that day, at least he wouldn't lick people, he just wanted to work hard, after all, the sense of accomplishment brought by finding evidence and helping to solve the case was indescribable.

"I don't know them, they just think of me as a student, they hit my bag at first, they don't say it, they dislike me for getting in the way, they just think I look like a student, and I still feel comfortable here."

Liu Yongxin smiled.

"Hey, my apprentice is with me, hurry up and compare, print out all the photos of the scene, compare the footprints of the port police station first, circle them with a marker, and send the rest to compare one by one."

Right here, Da Zhao sighed.

"Hey, why is there a QQ number hidden?"
