Chapter 70: Robbery vs. Vendetta
Zhou Ning raised his hand and pointed to the hand-drawn picture 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 were open, all the unpacked items were still there. Everything in the living room was deliberately smashed.
According to criminal psychology analysis, if the murderer wants to destroy the evidence at the scene, it means that he wants to hide some information, and this information may have nothing to do with the scene. In addition, valuables are still there at the scene, and the person who called the police also heard a sound.
Based on the existing evidence, my conclusion is:
There are one or two murderers, one of whom is suspected to be a woman or a thin man, right-handed, an acquaintance, and wearing gloves when committing the crime.
The intimidation began between 7:30 and 9:30 in the morning, and the time of the victim's death was close to the time the police were called. The murderer had a grudge against Wen Haicheng. I think this was a revenge murder disguised as a robbery."
"Gone?"
Zhou Ning nodded.
"The fingerprints on the murder weapon were compared. In addition to the two glove fingerprints, there were six complete fingerprints and seven incomplete fingerprints on it, including those of the deceased and his wife. There were also two incomplete fingerprints that were not found in the fingerprint database, but that fingerprint was covered with latex paint. I think it was left by the previous worker.
This is all the information we can get right now. The inspection report needs to be out early tomorrow morning. As for the footprints and movement tracks, we will compare them in detail after we return. The workload is huge and it can be completed tomorrow at the earliest.
However, in order to better draw the traffic flow diagram, I need the shoe prints and fingerprints of the person who called the police, Zhang Xin, the deceased's son and the deceased's mother. In addition, the deceased's laptop is with me, and the deceased's QQ number is logged on it.
You can ask the technical department to check. I remember there is a management of the associated number. If the phone is smashed, it is hoped that the information in the phone will not be leaked. The person who smashed the phone may not know that even if the phone is smashed, the information inside can be obtained. Of course, it is possible that it is too late to deal with it. "
Xu Dayuan looked at Liu Yongxin.
"Forensic Doctor Liu, is this the opinion given by your forensic department?"
Zhou Ning looked at Liu Yongxin with some concern. He had written these summaries in the car without communicating them with Liu Yongxin. Liu Yongxin just took a look at them.
"Xiao Zhou's opinion is my opinion. Let the technical department take a look at the computer first. Maybe they can find something."
Director Sun, who was standing next to Xu Dayuan, smiled, took out his cell phone, dialed a number, gave a few instructions, and then hung up.
"The technical department will be here soon. Let them restore the computer and two mobile phones. Just send someone to connect them."
Xu Dayuan nodded and looked towards Da Zhao.
"Zhao Xinli is in charge of the liaison. The special case meeting will be held here. He Chunyang will lead a team to continue investigating the social relations of Wen Haicheng and Zhang Xin, especially their design institute. The fingerprints and footprints will be collected and sent to the forensic room as soon as possible.
Liu Changhai will take people to the deceased's child's kindergarten to check the surveillance and ask the teacher what time Zhang Xin sent the child to school and when she left. He will also check the time with the community guard. All information will be collected at 10 o'clock tomorrow. The meeting is adjourned!"
At the order, everyone left. Zhou Ning stood up and was about to leave when Xu Dayuan coughed and waved at Zhou Ning.
"Director Sun has something to ask you."
Zhou Ning stopped and handed the autopsy report to Liu Yongxin, who gave him a comforting look.
"Xiao Zhou, I heard from Xu Dayuan that the software project you and Qindao University are working on is going very smoothly, right?"
Zhou Ning nodded. Actually, he had not been to Qindao University these days. He just communicated with Dr. Lu. In addition to software development, it seemed that they were hiring experts from medical schools and other famous universities to set up a forensic college. And not only undergraduates, but also master and doctoral students were going to be enrolled directly.
"Now the first basic data collection has been completed, and the AI technology program is being written. After this step is completed, the second data collection can be started. Here, AI technology can autonomously record relevant data, analyze and input it, and fill in the database content."
Zhou Ning spoke in a very conventional manner. After all, he had no idea what Director Sun meant by asking this question.
Director Sun nodded, with a smile on his face.
"Very good. I didn't expect that our Qidong Branch could produce such a talent. However, your main job is also very busy. Young people have a heavy burden on their shoulders. You must shoulder it well. By the way, I heard that you want to be transferred to the forensic department of the Municipal Bureau?"
Zhou Ning was stunned, his face full of confusion.
"I haven't heard about it. When did it happen?"
Xu Dayuan looked up and laughed, then moved closer to Director Sun.
"Is the boss worrying too much? I told you that you are overthinking. I personally picked this guy. If he has any plans, how could he not tell me? Please help us coordinate the technical department's matters, and don't worry about this."
Director Sun coughed twice and glared at Xu Dayuan.
"You're not polite when you're ordering your leader around. Okay, I know your team won't be distracted. Old Liu will leave soon. If Xiao Zhou leaves, we 'll just have to play the empty city plan."
Xu Dayuan waved his hand.
"Thinking too much. Who said that you have to go to the Municipal Bureau to do scientific research? Xiao Zhou has been working for half a year. I know this guy very well. He is a hard-working person.
He is not good at intrigue and deception. In his eyes, scientific research is just a side job. If he really wants to do this, why should he go to the Municipal Bureau? Wouldn't it be better to go to Qindao University?
Besides, if the leaders want to keep people, it's just empty talk without any real action. It seems that they have no sincerity. If they really want to keep people, they should apply for salary, which is the real benefit. "
Director Sun was stunned. He didn't expect Xu Dayuan to ask for such treatment. He thought for a moment and nodded vigorously.
"You're right. If we want to retain people, we need a mechanism. I'll report this to the leader when I get back. The salary cannot be changed, but the specific position allowances can be adjusted appropriately."
Zhou Ning pursed his lips, not knowing what to say for a moment. It seemed that what the two leaders were discussing was related to him, but not very relevant. However, who would object to getting more money? He just had to listen obediently.
Director Sun stood up and patted Zhou Ning on the shoulder.
"Okay, I'm going to interrupt the progress of your investigation. You guys are busy and I'll go coordinate other things. As the saying goes, this case is the most important. Don't let me down at the key points. I will be able to go to the Municipal Bureau with confidence."
Xu Dayuan smiled and stood up to see Director Sun out the door. After seeing him leave, Xu Dayuan rubbed his cheeks.
"Okay, get busy."
"Thank you, Xu Da."
Xu Dayuan waved his hand.
" So much nonsense. Oh, by the way, is Zhang Xin still awake?"
When he said this, Zhou Ning stopped.
"Before the autopsy, I went to the emergency department first. Her vital signs were good. The director of the emergency department said that she should be able to wake up, but she just didn't respond. I checked her injuries. In addition to the cuts, stab wounds, and blows, there was a fist-sized bruise on Zhang Xin's abdomen. It has begun to disappear. It should have been caused two or three days ago."
Xu Dayuan was stunned.
"You didn't say that just now. Do you suspect that the deceased had abused Zhang Xin?"
Zhou Ning shook his head.
"I'm not sure if it was caused by the deceased. I'm just stating the time when the bruise occurred. I'll compare it later. But as I investigate, I'm getting more and more confused. After all, there are many things in the evidence that don't make sense."
Xu Dayuan patted Zhou Ning on the shoulder. He could no longer describe himself as satisfied with such a subordinate.
"Don't be so sad. I remember you said that any contact will leave traces. Just because we haven't found any doesn't mean there are no traces. Let's look for them slowly."
Zhou Ning smiled.
"Then I'll be busy, leader."
Xu Dayuan waved his hand, and Zhou Ning returned to the forensic room. As soon as he entered the room, he saw Da Zhao and two other people sitting opposite Zhou Ning, fiddling with the computer. Needless to say, these were the people sent by the technical department to provide support.
Liu Yongxin looked at Zhou Ning, who hurried over and briefly explained the attitude Director Sun had just expressed. Liu Yongxin frowned slightly.
"There's no smoke without fire. Someone in the branch knows something. But I remember you said that when you went to Qindao University for a press conference, you met people from the Municipal Bureau, and it seemed that things didn't go well."
Zhou Ning nodded. In fact, this was what he was most worried about. Here he had a master to guide him. Even if the master retired, he could still get guidance by calling him.
If he really went to the Municipal Bureau, he really wouldn't be able to fit in with the two people he met at Qindao University that day. At least he wouldn't lick anyone. He just wanted to work hard. After all, the sense of accomplishment brought by finding evidence and helping to solve the case is indescribable.
"I don't know them, they just thought I was a student. Not only did they bump into my bag at first, they also complained that I was blocking their way. They just thought I looked like a student, and that planted the impression. I still feel at ease here."
Liu Yongxin smiled.
"Hey, my apprentice just follows me. Okay, hurry up and compare. Print out all the photos of the scene, compare the footprints from the Port Police Station first, circle them with a marker, and send the rest over one by one for comparison."
Just then, there was a cry of "hmm" from Da Zhao.
"Hey, why is there a hidden QQ number?"
