Serious Crime Unit 1

Chapter 1250 (9)
It wasn't until the suspect rode to the door of Jiangbei District Government that the outline of his face could be seen. This was a security monitor installed by the district government. The pixels of this monitor were as high as 3600 million. It was imported from Japan. The pixels are comparable to those of a professional camera, which can record various actions of the suspect from 200 meters away. The suspect passed this monitor at 7:18 on July 23, and the closest distance was only 23 meters. Therefore, the monitor captured him. Relatively clear facial contours.

Lu Yingying used software to fade away the suspect's helmet glass and restore his face. After more than three hours of modification, she finally fixed the suspect's face.She took the suspect's face to the database for comparison, and found that there were 41 people in the city whose appearance was more than 90% similar.

Lu Yingying patiently narrowed the age of the suspects to 28 to 32 years old. In the end, only 8 suspects matched the age. Combined with the height and weight of the suspects, only 3 people matched. If nothing unexpected happens, one of these three people must be It's the murderer.

"Captain Jiang, the fox finally showed its tail. Look at these three people. Their height and age are very similar to the suspect. I have found them out of the household registration system. Take a look. I suggest that these three people be investigated as soon as possible. Three people are conducting the investigation." Lu Yingying handed the printed information to Jiang Yiming, which contained the suspect's identity information.

He took it and looked at it and said, "Great, do you see where the suspect came from?"

"No, we tracked it through surveillance video. The first time he came out of Qian Village, but when he returned, he entered Lishan Village. The second time he came out of Fang Village, and when he returned, he entered Guanxia Village. He was playing hide and seek with us. , because some alleys in these villages do not have monitors installed, or the monitors are broken."

"What do you think is the quickest way to identify one of them as the murderer?" Jiang Yiming asked happily with a smile.

"Captain Jiang, please don't test me. I'm in charge of video investigation and IT technology. I don't want to take credit from you for identifying the suspect."

"What are you talking about? Am I not acting according to the principle of brainstorming?"

"Let me think about it... didn't the suspect leave shoe prints on the back hill? Angkor and Xiao Ke could judge the suspect's information from his gait, and summoned the three of them to the criminal police team to let Angkor take a look. Their gait identifies the suspect."

"Gao! He is indeed the elite of our criminal police team. There is another way for Ji'an to identify the suspect." Jiang Yiming said.Lu Yingying extended her thumb to him, then turned and left.

He got up and walked out of the office, explained the situation to Wu Jiang and Xiao Ke, and asked them to verbally summon Lin Ziming, one of the suspects. He and Zhou Ting went to summon Hua Baifang, one of the suspects, and another suspect named Ma Yuan. , Jiang Yiming asked Luo Jin and Lu Yingying to summon them, because there is currently no evidence to prove that they are the murderers, so there should be no danger.

However, things are not as simple as they imagined, and even subvert their previous understanding.

The three suspects were summoned to the criminal police team one after another. They were very calm and did whatever they were told to do.Their walking gaits were filmed, and Wu Jiang and Xiao Ke analyzed them with a gait analyzer. The results showed that two of them had completely different gaits from the suspect, while Hua Baifang's gait was only 65% ​​similar to the suspect's. .

If the gait similarity rate reaches 65%, the suspect cannot be identified, and it must be over 95% to identify the suspect.This disappointed Wu Jiang, but they also had a trick in the works, which was to let Ji'an identify the suspect's face and voice.As a result, Ji'an actually said that he did not see the suspect's appearance under the dim light of the mobile phone flashlight, and the flashlight on the suspect's mobile phone only shined on him, not on himself at all.

Jiang Yiming asked Ji'an to carefully identify the suspect's voice. After listening to it many times, Ji'an still couldn't determine which one was the suspect.Jiang Yiming thought he was shielding the suspect.He cried that he had been wronged.Jiang Yiming saw that he didn't look like he was lying, so he finally had to give up and let him identify the voice.

Jiang Yiming believed that one of the three suspects deliberately changed his voice to negotiate a deal with Ji'an. However, it is difficult to learn to change his voice and it takes a long time to practice. So, is there a way to change his voice under the influence of external forces?
Jiang Yiming asked Lu Yingying, and she said: There is a necklace-shaped voice changer. As long as it is wrapped around the neck, it can change the sound at will according to the vibration of the throat. The tip can penetrate the cervical cord, and women can also do it.After hearing this, he felt incredible. Nowadays, black technologies are emerging in endlessly and changing with each passing day. If you don't study hard, you will really fall behind.Fortunately, Lu Yingying is here as a treasure.

In this case, they must use another trick, asking the three of them where they were at the time of the crime.what are you doing?There's no way they can be invisible, right?
"Mr. Hua, where were you from 7:20 to [-]:[-] in the morning on July [-]th? What were you doing?" Jiang Yiming first asked Hua Baifang, while Wu Jiang and Xiaoke asked Li Ziming.Jiang Yiming asked Lu Yingying and Wen Xiaorou to ask Ma Yuan.

"It's been 11 days, I can't remember." Hua Baifang opened a relatively small trading company, and the profits he earned were enough to make him live comfortably.He is 36 years old and has not yet started a family. He is low-key and introverted, good at thinking. He likes to play Go the most. He is the secretary-general of the Municipal Go Association and once won the second prize in the provincial Go competition.

"Think about it carefully. This will help eliminate your suspicion. You are a young man and a Go master. You have a super memory, otherwise it would be impossible to become a Go player. You should not forget 11 days so quickly. What happened before?" Jiang Yiming thought that he deliberately concealed the facts.

"Hmm...oh, I remembered that that day Wu Jie and I were playing Go at the Fangpu Chess and Cards Club. Wu Jie is an honorary member of our Go Association and loves playing Go very much. Of course, her and my chess skills are the same. Therefore, she often asks me for advice." "Where is the Fangpu chess and card club? Why have I never heard of it?"

"Oh, below the Butterfly Valley in Longtou Mountain is a small chess and card club that just opened. It was founded by Gu Huang, the president of our Go Association, at the request of hundreds of members. It used to be a drug manufacturing factory. Later, the factory was taken over by you. After it was dropped, Gu Huang rented the factory and renovated it. It has just been open for about 20 days. It has a catering department, a guest room department, and a small conference room. There are a total of 28 simply decorated chess rooms. "

"Does the club have business in such a far place?"

"The business is not very good at the moment, but because the cost is relatively low, it will not lose money. Gu Huang does not expect the club to make money. He only hopes to provide a good place for Go enthusiasts and unite with everyone. Gu Huang is engaged in medical equipment Yes, in the past three years since the outbreak of the new coronavirus, the masks and nucleic acid test kits they produced have been very popular and they have made a lot of money."

"Tell me about Wu Jie's situation."

"Wu Jiang is a designer at Hailang Clothing Company in our city. She is 30 years old and unmarried. She once won the provincial gold medal for designers. However, she prefers playing Go. She said that Go can not only cultivate the mind and character, but also increase wisdom. So, when she gets tired from working in the company, she will invite me to play chess at Fangpu Chess and Card Club."

"You actually play chess until 2:[-] in the morning?" Jiang Yiming thought he was lying.

"I don't know why, but she was very excited that day and insisted that I play chess with her. I couldn't refuse, so I had to bite the bullet and play chess with her. I didn't expect that she actually beat me three games in a row. I was not convinced and mentioned ten I was full of energy and played another game with her, but she was defeated by me. Only then was she willing to admit defeat. The next game of chess takes about an hour, of course, unless the level difference between the two is too big, the game will end in a short time. "

Jiang Yiming and Zhou Ting finished questioning Hua Baifang and then drove to visit Wu Jie.

Wu Jie is small and exquisite, with a pair of big talking eyes, skin as white as snow, elegant temperament, and long hair that reaches her waist.She said that she was indeed playing chess with Teacher Hua Baifang at that time. She was very excited that night and it didn't end until 02:30 in the morning. After that, they had a bowl of instant noodles and opened two rooms at Fangpu Chess and Card Club. He went to sleep, and when he woke up, he continued to play chess until the early morning of July 7 before returning to the city.

Jiang Yiming saw that she didn't look like she was lying, so he ended the inquiry and drove towards Butterfly Valley with Zhou Ting.They knew the location of Fangpu Chess and Cards Club very well and had been there at least five times, so they drove up the winding mountain road with familiarity and turned the car into Fangpu Chess and Cards Club halfway.

After they parked the car, they didn't have time to admire the flowers and trees inside and outside the club, so they went directly to the manager to ask about the situation.The manager's name was Yu Xin. He said it was so late and the waiters had already gotten off work, so there was no way to prove that Hua Baifang and Wu Jie were playing chess in the 112 chess and card room.Because members have their own fixed room key, they can enter at any time and are not under their control.

The manager said that as long as there are chess players playing chess in the club and the room door is opened with the room card, the monitor in the room will automatically run and record the chess game between the chess players, especially the game between masters like Hua Baifang and Wu Jie. The captured videos can be used as learning materials for members.

"Has the surveillance video of Hua Baifang and Wu Jie's game been saved?" Jiang Yiming asked.

"Of course, otherwise we would be remiss in our duties. We are a membership system. You can open the door and use it by yourself as long as you use your membership card."

"Have you installed a monitor at the gate?"

"Oh, we are preparing to install the monitor, but the technician responsible for building the monitoring system was too late to install it, so he only installed the monitor in the chess and card room... We are in trial operation, and many of the equipment are not perfect yet. We will follow up in time. Don't worry Right." Yu Xin said sincerely.

"Take us to see the surveillance video of Hua Baifang and Wu Jie playing chess."
