Serious Crime Unit 1

Chapter 904 Jumping off a Building (7)
"We have checked the surveillance video from 6 a.m. to 22 a.m. on June 10, and no suspicious person has been found yet. However, we unlocked Jin Jieying's mobile phone password and found in the message box of the mobile phone that Jin Jieying was playing tricks on the future. The video of the adult girl was sent to him from an unfamiliar mobile phone number. The suspect should have used this video to threaten Jin Jieying and force him to go to the unfinished building to meet the murderer," Lu Yingying said.

"Has the owner of the suspected mobile phone number been found?"

"I called the phone owner, but couldn't get through. Wen Xiaorou and I went to the mobile company to check the suspect's identity information. However, the mobile phone number belonged to a citizen of Yan'an City. He had been dead for 8 months. The murderer was counter-investigated. The ability is very powerful, I suspect that the murderer’s mobile phone card was purchased online.”

"It's strange. The murderer is tall and his footprints disappeared on Jinhua Road next to the unfinished building. How come no suspicious person was found? Please extend the time to check the surveillance video. Maybe the murderer is hiding in the unfinished building, waiting for us. What if we go out after surveying the scene?”

"There is no such possibility, because the time when we tracked the suspect's footprints was close to 12 o'clock, and the suspect must have left the scene before 6 o'clock on June 22." Wu Jiang said.

"I think the murderer should know Chen Mingshi, Song Shiguan and Jin Jieying, and know their whereabouts very well. Otherwise, the murderer would not be able to film the video of Jin Jieying playing with minors."

"Yingying, how was Limin Pharmaceutical Company's monitoring system destroyed?"

"Oh, the hacker attacked the host, causing it to be paralyzed by poisoning. This is a super Trojan horse, which is not something ordinary hackers can do. I suspect it may be Xie Chong, because he is in the IT industry and has the ability to break into malicious software. The firewall of the private company's computer. If there is a spy cooperating with him, it will be easier for Xie Chong to succeed."

"Lao Wu and Xiao Ke continued to question Xie Chong, asking him where he was at the time of Jin Jieying's death? If he does not have an alibi, then he has huge suspicions. I think it is very likely that it was an insider from Limin Company. If this is the case, as long as biological samples are extracted from the suspects, their DNA is prepared, and compared with the DNA left on the skin between Jin Jieying's fingernails, the murderer can be arrested."

"Yes, but it would be more time-consuming to do DNA on all the suspects' biological samples." Luo Jin said.

"It doesn't matter if it takes time. This is what we eat. We first extract biological samples from men with a height of 175 centimeters or more in Limin Company, and then do DNA one by one. This will save a lot of time. If it doesn't succeed, Then take biological samples from men under 174 cm. In order to prevent alerting the snake, I sent a surveillance team to monitor the suspicious man in Limin to prevent him from escaping. Luo Jin went with me and Zhou Ting, while Yingying and Xiaorou continued to check Surveillance video." After Jiang Yiming finished speaking, he stood up and walked out of the conference room.

Jiang Yiming, Zhou Ting, and Luo Jin went to Limin Company, visited Jing Xing again, and asked him to find out the information of men with a height of over 175 centimeters and give it to them. Jing Xing thought for a while, turned on the computer, and searched in the employees' electronic files. , it was found that there were 399 employees in the company who were above 175cm tall.

Jiang Yiming asked him to first find out the information of the male employees who worked in the company on the night of Song Shiguan's death.This narrowed the scope a lot, so Jingxing went to check for qualified employees, and found that only 9 employees met the requirements.

Jing Xing printed out the list of these 9 people and gave it to Jiang Yiming. Although Jing Xing was also over 175cm tall, he was under police protection 24 hours a day. He could not go to the unfinished building to kill people, so there was no need. Extract his biological samples.

Jiang Yiming asked Jing Xing to call all nine employees to the office and explain that he could not just say that the police were looking for them and just want to hold a meeting.So Jing Xing called various employees, and within half an hour, they all came one after another, but only 9 people came. One person named You Lihong, who is the office director of the sales department, did not come.

Jiang Yiming asked Jing Xing why Lihong didn't come?Jing Xing said he didn’t know and would have to call the HR manager to find out.So, he picked up his landline and called the manager of the human resources department to inquire. The manager said that You Lihong was on leave for a week and said he was going to Huangshan for a trip. He had already been there for two days.

Luo Jin and Zhou Ting quickly extracted the biological samples of the eight employees. Jiang Yiming felt that You Lihong was very suspicious. He may also have thought that the police would extract the biological samples of the suspects for DNA comparison, because he knew what he had in his hands. He was caught by Jin Jieying, leaving fatal evidence to the police.

Jiang Yiming asked Jing Xing to call You Lihong and ask where he was.If the call goes through, ask him when he will be back?Jing Xing did as Jiang Yiming said and called You Lihong's mobile phone, but couldn't get through.Jiang Yiming thought he should throw away the mobile phone card and fled in fear of crime.

Jiang Yiming asked Jingxing where Lihong's office was?Have you ever smoked?Jing Xing said that he smoked. He took Jiang Yiming and the others to Yu Lihong's office booth and tried to find You Lihong's biological samples, such as cigarette butts and hair. However, his office booth was cleaned very clean.Can't find what they want.Jiang Yiming asked Luo to go into the car to get the multi-band light source. So Zhou Ting walked out of the office area and went to the car to get the multi-band light source. After getting it, he turned on the multi-band light source and illuminated everything that You Lihong had used. As a result, he found that Yu Lihong There were many sweat stains on the used mouse. Zhou Ting took out a cotton swab to extract the sweat stains. Then he found a lot of skin flakes in the gaps between his keyboard and also extracted the skin flakes.

After returning to the team, Luo Jin and his assistant conducted DNA testing on You Lihong's biological samples, entered the test results into the computer, and compared them with the DNA of the skin tissue left under Jin Jieying's fingernails. The results were completely consistent, which can prove that You Lihong was murdered. After the results of Jin Jieying's murderer came out, everyone cheered together.

Jiang Yiming asked Wen Xiaorou to search for You Lihong on the Internet, and offered a reward of 3 yuan to anyone who found major clues, and a reward of 6 yuan to the individual or unit who caught the murderer. The mobile phone numbers of Lu Yingying and Jiang Yiming were left on the wanted order.At the same time, the wanted order is uploaded to the collaborative case handling system.

The wanted order will be sent to the public security bureaus of each province within one hour, including the wanted person's name, gender, age, physical characteristics, recent clear photos and other relevant content, and will be sent to the police station, public security, inspection and inspection department within 12 hours. In the hands of every combat team member in the prison, prison and other departments.

This is a powerful tool for discovering and arresting criminals. Unless the suspect hides abroad, it will be difficult to hide because surveillance systems in many places now have face recognition functions.Once a criminal is captured by the facial recognition monitor, the system will automatically sound an alarm, and nearby police will immediately go to arrest him.

Wen Xiaorou searched the National Accommodation Registration System to see if You Lihong had registered for accommodation with his ID card. The query showed that he had not checked in, which meant that he might have used someone else's ID card to register for accommodation, or he might have stayed in a small hotel that did not require ID card registration.

Wen Xiaorou was worried that You Lihong had fled abroad. She called the Exit and Entry Bureau to check, but found that there was no registration for him to leave the country. Unless he smuggled out of the country, the Exit and Entry Bureau must have registered him.If he had made arrangements in advance, it would be easier to sneak into neighboring countries from Yunnan and Guizhou.However, it has only been two days since the incident, so the possibility of Yu Lihong sneaking out of the country is very small.

Two days later, the Public Security Bureau of Yuxi City, Yunnan Province called Jiang Yiming. They had captured You Lihong and asked them to go to Yuxi City to escort him back. As expected, You Lihong was going to have his friends in Yuxi City get him from the border. He smuggled himself out of the country, but when he took to the streets, he was recognized by the face recognition system of the Yuxi City Security Monitor. The 110 Command Center of the Yuxi City Public Security Bureau immediately ordered the nearby patrol police to arrest You Lihong. As a result, You Lihong was arrested obediently.

Jiang Yiming asked Zhou Ting and Xiao Ke to fly to Kunming to escort You Lihong back, because the Yuxi City Criminal Police agreed to escort You Lihong to Kunming, waiting for them to escort him. Xiao Ke bought a round-trip air ticket online and flew to Kunming with Zhou Ting.

Xiao Ke and Zhou Ting arrived in Kunming at noon. After seeing Xiao Ke and Zhou Ting, their colleagues in Yuxi praised them for their speed in doing things and invited them to lunch, which moved Xiao Ke and Zhou Ting very much.After they had lunch, they went to the detention center to pick up You Lihong, handed him over to Xiao Ke and Zhou Ting, and took him to the plane before going back.

At 4 o'clock in the afternoon, Zhou Ting and Xiao Ke successfully escorted You Lihong to the Municipal Bureau's Criminal Police Team and put him in the interrogation room. Jiang Yiming, Wu Jiang, and Wen Xiaorou immediately interrogated You Lihong.

You Lihong was very calm, as if he had known that such a day would come. Of course, maybe he was pretending to be calm, because few people can be so calm in the face of life and death, unless his psychology is abnormal.

"You Lihong, please tell me about the process of murdering Song Shiguan and Jin Jieying." Jiang Yiming walked to the interrogation chair, rolled up his shirt sleeves, and saw two shallow lines on his right forearm. Needless to say, the scars were caused by Jin Jieying scratching his forearm with his nails the moment he fell from the building.

"I want you to show me the evidence of my murder." He said calmly, without any trace of panic.

"Actually, you know very well what evidence we have to prove that you murdered Jin Jieying. If you want to see it, I can give you the evidence. We found skin tissue between Jin Jieying's fingernails. After DNA testing, it belongs to you. Yes, because the moment he fell from the building, he scratched your forearm with his hand, and those two scars are still left on your forearm."

"How can you prove that the skin tissue between Jin Jieying's fingernails was left by me?"
