The rise of nanometers

Magic City.

Police autopsy centre.

After Zhao Xiaojun's body was discovered, he was immediately sent here.

Under the cold air-conditioning and cool lights, three forensic doctors wearing protective suits first conducted a comprehensive physical examination.

"The stains on the corpse are cherry red, and there is obvious carbon monoxide poisoning." The old forensic doctor explained the inspection situation while examining the corpse.

The intern forensic doctor on the side was immersed in writing.

The old forensic doctor continued: "The body was lying flat and there was no obvious sign of struggle, which is consistent with the characteristics of suicide by burning charcoal."

"Judging from the body spots and rectal temperature, the time of death was 27 to 29 hours."

Another medical examiner drew blood from three areas of the body in preparation for a carboxyhemoglobin test to determine the accurate time of death.

Suddenly the old forensic doctor's hand stopped.

"What's wrong? Did you find anything?"

The old forensic doctor carefully pressed the abdomen of the corpse and found an obvious mass: "This person may have intestinal tumors. We will conduct an autopsy to confirm it later."

After more than three hours of autopsy examination, Zhao Xiaojun's time of death was confirmed to be April 11, 2010, between 2 and 3 am.

The fatal cause was carbon monoxide poisoning caused by burning charcoal. However, during the autopsy, the forensic doctor discovered that he had terminal colon cancer and that even if he did not commit suicide, he would not be able to survive for half a year.

Li Dongfeng, the leader of the task force responsible for the investigation, quickly deduced the ins and outs of the Herborist incident by combining it.

Inside the task force office.

Several veteran detectives were discussing the case while looking at it. The scene was filled with smoke.

"Lao Zhang, smoke less." Li Dongfeng's head was swollen by the smell of cigarette smoke.

However, Lao Zhang, a long-time smoker, didn't seem to hear it. After taking a deep breath, he blew out a smoke ring: "This yellow and red star has serious suspicions."

Li Dongfeng said angrily: "Of course I know this guy is suspected. The question is where is the evidence? This guy is very smart. He apologized profusely on the Internet, saying that he mismanaged it. Now everyone is watching, so don't mess around."

Lao Zhang put out the cigarette butt: "Have you investigated his property?"

"I checked, even his family's accounts, and there was nothing unusual. On the contrary, it was Zhao Xiaojun's ex-wife who had more than two million yuan of unidentified money, remitted from overseas, and the remittance bank account was with a Swiss bank. ." Li Dongfeng shook his head helplessly.

"Obviously he knew he was dying and took the opportunity to make a fortune for his family."

Another person pointed to the autopsy report and hospital records: "Zhao Xiaojun discovered that he had colon cancer during a collective physical examination of Herborist employees in January this year. According to his family and friends, no one knew about it. .”

"No, someone knows, this Huang Hongxing must know." Lao Zhang lit up a cigarette again.

Li Dongfeng grabbed his hair and said with a headache: "Evidence, I need evidence, not reasoning. As long as the other party refuses to speak, there is no way to convict."

"How about conducting an investigation from the people who have recently come into contact with Zhao Xiaojun?" Another police officer suggested.

"All right!"

Li Dongfeng's pocket vibrated. He took out his mobile phone and found that it was a superior's number, so he had no choice but to call it.

I thought it was another urging to solve the case, but after listening, I found out that Suiren Company sent a professional team to assist in the investigation.

That night, Huang Weichang, who hurriedly came from Shanmei, brought the professional team of Suiren Company's security department to join Li Dongfeng's task force.

Although Li Dongfeng was not optimistic about the security department of the Suiren Department, he did not stretch his hand to hit the smiling man. He was kind enough to come to help. In addition, this matter was the vital interest of the Suiren Department, so Huang Weichang could only be allowed to join.

Magic City, the data center of the Sky Eye System.

Huang Weichang, Li Dongfeng and others came here together.

"Mr. Huang, this is the data center of the Magic City Sky Eye System. This is the person in charge of the data center, Director Su Jintian."

Huang Weichang stretched out his hand and shook hands with the thin, middle-aged man with glasses: "Hello, Director Su."

"Mr. Huang, you're welcome. The database in our data center is still your company's product." Su Jintian said with a smile.

After a few people chatted for a while, Huang Weichang got into the topic and asked the personnel from the Suiren Security Department to connect several laptops to the Sky Eye system.

Instantly connected through the laptop, the database of the Magic City Sky Eye system, and the Haifeng Data Center of Time Information.

After entering all of Zhao Xiaojun's information, information screening was started. Zhao Xiaojun, whose scope of activities was relatively fixed, could not escape the information screening at all.

The comprehensive screening system developed by Time Information combines big data, face recognition, human sociology, human psychology, plus kinematics, climate temperature, urban transportation, etc.

Through this information, Zhao Xiaojun’s entire activity trajectory from January 1, 2010 to April 11, 2011 was reconstructed.

After comprehensive analysis, they quickly targeted some areas of Zhao Xiaojun's daily activities, in addition to factories, home addresses and vegetable markets.

As a veteran detective, Lao Zhang focused on the 10 days before and after the crime: "Brother, can you call up this guy's activity trajectory in the past 10 days?"

The programmer who assisted in the investigation nodded. After entering the date conditions, only the activity tracks of the past 10 days were left.

Lao Zhang immediately discovered the problem: "Team leader, I found out that this guy had been to this small park the day before committing the crime and that night."

The programmers immediately mobilized the monitoring data of the park and its surroundings from April 4th to April 5th. If manual screening was used, the speed would be slow and there might be omissions. The comprehensive analysis of the system locked ten people in an instant. A few images.

Zhao Xiaojun appeared in the picture, and there were signs of a brief exchange with a man wearing a peaked cap and a mask.

"Can I target this person?"

"Let me give it a try." The programmer started trace tracing based on the cap's movement trajectory and clothing characteristics.

Although the peaked hat deliberately took the bus and went to several other densely populated locations, he was still locked in his location.

"He went to Qingpu District Western Garden twice. It seems that this is a key location."

Li Dongfeng turned around and ordered: "Go to Qingpu District Western Garden immediately and copy back the recent monitoring data."

"clear."

Lao Zhang, who was deep in thought, subconsciously wanted to smoke, but was slapped by the sharp-eyed Li Dongfeng before he smiled awkwardly.

But he seemed to have thought of something: "Brother, enter this person's information and conduct a screening. The conditions are still within 10 days."

The case information given by Lao Zhang was exactly the details of Huang Hongxing.

The programmers immediately conducted the screening, and soon the data came out. Everyone's eyes lit up because they found that this yellow-red star had been to the Western Flowers in Qingpu District on April 3, April 4, and April 6. Garden.

Lao Zhang immediately suggested: "Team Li, adjust Huang Hongxing's social relations and see if there are any acquaintances living in Western Garden, Qingpu District."

"no problem."

Two hours later, it was already two o'clock in the morning in the dead of night, but the lights in the data center were still bright.

All the internal surveillance of Qingpu District Western Garden has been copied, and among Huang Hongxing's social relationships, there is indeed a person living in Qingpu District Western Garden.

After comparing internal surveillance data, the identity of the peaked cap was determined to be a friend of Huang Hongxing's from the same village, and this guy lived in Xihuayuan, Qingpu District.

Li Dongfeng basically confirmed Huang Hongxing's suspicion: "It seems that we are getting closer to the truth."
