Serious Crime Unit 1

Chapter 843 Indirect Murder (8)
"We found the suspect in the surveillance video of the crime scene. Because it was raining and the lights were dim, the suspect's face was not very clear. However, after technical processing, the surveillance video was processed more clearly. We Take a screenshot of the suspect's video. Then print it out and find that you are the person we are looking for."

"Humph, that's ridiculous! I'm living a good life, why should I kill people and push myself to a dead end?" He asked angrily, as if Wu Jiang had slandered him.

"We don't know your motive for killing yet, but your appearance and facial features are very similar to the suspect. That's why we came to find you. You'd better confess the truth. Resistance will only bring you death."

"Why do you have the right to say that I killed...what...Linjang? Show me the evidence. I'm not afraid of death. People will die sooner or later anyway, but I don't want to die unjustly by you."

"Since you don't want us to wrongly accuse you, you have to cooperate with us in handling the case to eliminate your suspicion."

"You come to my house without any evidence and accuse me of being a murderer. I want to cooperate with you, but you are not in the mood."

"It's very simple. Just tell us where you were from 17 to 1 a.m. on the 2th of this month." Although Liu Yong's tone was full of anger, Wu Jiang told him calmly. After all, there is no evidence of his murder yet. .

"I must have been sleeping at home."

"Today is the 27th, 10 days have passed. Can you remember it so clearly?"

"Yes, I have a very good memory."

"Can anyone prove it?"

"I slept alone and no one can prove it."

"You are legally responsible if you lie."

"I know that. I studied law before."

Wu Jiang took out his mobile phone, pulled out the screenshot of the suspect's video from the gallery, handed it to Liu Yong and said, "Look at this photo, is that person you?"

He reluctantly took Wu Jiang's phone and looked at it. The moment his eyes met the screenshot, he was slightly stunned, and then said: "This is definitely not me, officer, you have found the wrong person."

Wu Jiang couldn't figure out why he was stunned, so he had to ask him to walk a few laps in the living room. After hearing this, Liu Yong stood up and walked a few laps in the living room according to Wu Jiang's instructions. Wu Jiang recorded his walking posture on his mobile phone. Here, they are going to take it back to the criminal police team for comparison with a gait analyzer, so that they can make an accurate judgment. I hope Liu Yong is the real murderer, otherwise, they will continue to look for new clues.

Human movement is the result of the nervous system controlling the rhythmic contraction of more than 1000 muscles and driving more than 200 bones to move cooperatively around more than 100 joints. Therefore, a unique gait is formed, and the gait is as exclusive as DNA.

The gait analysis system is the most commonly used equipment for detecting macroscopic movements of human limbs. It mainly studies the technology and devices for gait analysis through image processing of human movement images obtained by ordinary cameras.The content involves the detection and analysis technology of human body movement trajectory, ground support reaction force and surface electromyography signal.

Wu Jiang input the video of Liu Yong walking into the computer and used a gait analyzer to scan and analyze it. The result was: Liu Yong was not a suspect at the crime scene!This disappointed Wu Jiang and Xiao Ke. Wu Jiang went to Jiang Yiming's office and told him the result.

"Can gait be disguised?" Jiang Yiming knew that gait was extremely difficult to disguise, but he still asked, "I mean, is there anyone who is particularly good at camouflaging gait?"

"It's impossible. It's possible if you deliberately disguise a few steps. But the suspect and Liu Yong both walked dozens of meters. It's extremely difficult to disguise such a long distance. What's more, the murderer fled nervously after the murder, and it's even more impossible to disguise .”

"Does Liu Yong have a twin brother?"

"No, even if there are twin brothers, the gait cannot be exactly the same, just like the fingerprints of twin brothers are different."

"Then does Liu Yong have cousins ​​who look similar to him?"

"We haven't checked this yet. Oh, I remembered it. The moment Liu Yong's eyes came into contact with the suspect's screenshot, he was slightly stunned. It seems that Liu Yong knew who the suspect was. Captain Jiang, Your idea was like a flash of lightning, opening up my mind. Xiao Ke and I followed your line of thought to investigate." Wu Jiang was very excited.

"First summon Liu Yong for questioning."

"I think Liu Yong has a stubborn temper. He is very dissatisfied with us for soiling his floor and treating him as a suspect. He may not necessarily cooperate with us."

"Try it first. If he doesn't say anything, then find another way. This way you can avoid detours."

"Ok."

Jiang Yiming issued a summons to Wu Jiang and asked him and Xiao Ke to bring Liu Yong back for questioning. Wu Jiang collected it and went out.Wu Jiang and Xiao Ke went to Liu Yong with the summons. Liu Yong was very resistant. Liu Yong said that he was not a criminal suspect and the summons was invalid for him. At most, he could only be given an inquiry notice.It seemed that he knew a lot about the law, so Wu Jiang had to patiently persuade him to go to the Criminal Police Team to cooperate. Finally, Liu Yong returned to the Criminal Police Team with them.

But Liu Yong refused to admit knowing the suspect in the screenshot. Jiang Yiming said to him: "If we find out that you know the suspect, then we have the right to detain you for the crime of obstructing official duties, and the time limit is determined by us. If In this case, you will be blacklisted by us, which will be very detrimental to your future future. Please think carefully before proceeding."

Liu Yong was silent for a long time. He was debating whether to tell the truth or not. In the end, he said: "The person in the screenshot looks a bit like my cousin Liu Kuangye, but I can't confirm it. However, I believe he will not kill anyone." , because he is kind."

"There is a gap between people's hearts. People who are kind to their relatives may not be kind to their enemies. Thank you for your cooperation. You can go." In order to express his sincerity, Jiang Yiming walked him to the gate.

Liu Kuangye was born on January 1980, 1. He lives in Guangming Community, No. 3 Mingzhu Street, Jiangxi District. He is married and has an 121-year-old daughter. His wife opens a milk tea shop next to the community. He himself is a courier for Yunda Company. member.

Wen Xiaorou saw Liu Kuangye's ID card photo from the household registration system. She downloaded the photo to her computer and compared it with the software and the screenshots of the video. The results were exactly the same. Wen Xiaorou was immediately reassured because the face recognition system she used was very High-end, with almost no error. Even if there is no other physical evidence, Liu Kuangye can be convicted with the face recognition system and gait recognition system.

However, it is a bit strange: from the results of the investigation, Liu Kuangye and Lin Jian had no intersection and they did not know each other. Why did Liu Kuangye kill Lin Jian?Of course, their investigation cannot go deep into everyone who knows Lin Jian. Maybe Liu Kuangye and Lin Jian had an accidental conflict, such as a car crash.

Although I don’t understand Liu Kuangye’s motive for killing, I can arrest Liu Kuangye based on the above two points.Jiang Yiming, Zhou Ting, Wu Jiang, and Xiao Ke went to Liu Kuangye's home to look for him.If he is at home, arrest him immediately.

Liu Kuangye lived in Room 19, Building 504, Guangming Community, and lived with his parents. Zhou Ting knocked on Liu Kuangye's door. The person who opened the door was an aunt in her 60s, who should be Liu Kuangye's mother.

"Who are you?" she asked doubtfully.

"We are from the Criminal Police Team of the Municipal Bureau. Is this Liu Kuangye's home?"

"Yes, I am his mother. What crime did my son commit?" She was relatively short, looking up at Jiang Yiming and asked.

"Shall we go into the house?" Jiang Yiming asked, and she nodded, so they walked into the living room together. After they sat down, Jiang Yiming asked her, "Is he at home?" He didn't want to say that he killed someone, so as not to scare her. .

"I don't know where he has been in the past two days. I couldn't get through to him on the phone. My wife and I are very worried. Have you found him?"

"No, if we find him, we don't have to come to your house to look for him. Please give us Liu Kuangye's phone number and we will find ways to help you find him. We will definitely have more ways than you."

She spoke a string of numbers. Jiang Yiming entered the numbers into the dial pad of his mobile phone and then dialed. As a result, a voice came from the system: The number you dialed cannot be connected at the moment. Please call again later... Jiang Yiming was afraid that she made the wrong call to Liu Kuangye. I asked her to confirm my mobile phone number. She said it was correct, it was this number.

"What brand of mobile phone does Liu Kuangye use?"

"It's Apple 8."

Jiang Yiming nodded and looked around the house. It was a house with three bedrooms and one living room. Except for the living room, the doors of the three rooms were all closed. He was afraid that Liu Kuangye would be hiding at home, so he asked her to close the three doors. They were all opened, so she had to take out the key, open all the doors, and let them check. As a result, there was no one in the room, nor in the bathroom or kitchen.

"What kind of crime did my son commit?" she asked eagerly again, with anxiety in her eyes. Before she retired, she was a clerk in the district government office. Of course she knew what it meant for the criminal police to come to her son. If it was a small matter, it would usually The police from all police stations came forward.

"It's not certain yet, he's just a suspect."

"What type of suspect is this?"

"It's not convenient to tell you, but you have to be mentally prepared. What Liu Kuangye committed is by no means a small crime. Where does Liu Kuangye usually go?"

"He is a model husband who cares about his family. He rarely goes out to play except delivering express delivery. Because there are no weekends and holidays when delivering express delivery, he is so tired that he just wants to lie down and sleep. Fortunately, he is in good health and has never been sick, so he can Can handle this job."

When they walked out of Liu Kuangye's home, Jiang Yiming did not expect that they would miss them. He asked Wu Jiang: "Will Liu Kuangye abscond in fear of crime?"

"Except for Liu Yong who knew we were looking for him, no one knew we had found him. How could his sense of smell be so sensitive? It shouldn't be possible."

"What if Liu Yong informs him to escape." Xiao Ke said.
