Serious Crime Unit 1

Chapter 129 The mystery of falling from a building (12)
5. Pursue

There is no perfect murder in the world. Birds flying across the sky will leave shadows on the earth, and the wind blowing from the forest will make sounds. Therefore, finding evidence will not be a problem for those who have repeatedly solved major cases, important cases, strange cases, and mysterious cases. Crime Unit.

Rocca, a famous French forensic scientist and criminologist, said: Whenever two objects come into contact, physical evidence will be converted, and some things will be taken away and some things will be left behind.

He has a famous saying: "Every corner he (the criminal) stands, every artifact he touches, everything he leaves behind, even if he is unconscious, will leave a silent witness against him. Not just His fingerprints and footprints, his hair, the fibers on his clothes, the glass he broke, the tools he left behind, the paint he scraped off, the blood or semen he left or collected, all these and more, All support the silent witness against him..."

The crime team extracted Liu Bangbang's fingerprints on Wang Limei's balcony and wall. These fingerprints were very clear, enough to prove that Liu Bangbang stepped from the balcony to the air conditioner. Of course, he did not expect that the air conditioner bracket could not bear his 75 It broke under a kilogram of weight. He was caught off guard and fell instantly, all the way to hell.

Liu Bangbang's death was a well-planned murder. The story should be like this: Liu Bangbang was greedy for Wang Limei's beauty, and Wang Limei was forced to commit herself to him. In order to avoid future troubles, she designed to get rid of Wang Limei. I didn't expect Wang Limei to have such a sinister heart hidden under her beautiful appearance.

In order to find out how Wang Limei hid from the surveillance video, Jiang Yiming and Xiao Ke came to Longkou Community again to investigate.Building 9 has a total of 6 units on each floor. Every two units has a gate, with a total of 3 entrances and exits. Wang Limei lives on the 8th floor of the first unit, which is also the top floor.

They called up the surveillance video of the gates of the second and third units and started to check. They saw Wang Limei appearing at the gate of the second unit at 22 o'clock. There was a man in front of her who opened the gate with a key and walked in. Before the gate was closed, She opened the door smoothly and followed the man in.

Jiang Yiming and Xiao Ke already roughly knew Wang Limei's plot. To confirm, they walked into the door of the second unit and went to the top floor. There was a small door on the top floor leading to the rooftop, and a small lock was hung on the small door. , Jiang Yiming wanted to call the property manager, but Xiao Ke told him not to fight. It was too easy to deal with such a small lock. Xiao Ke magically took out a key from his pocket and said, "I seized this from a thief." The master key is very useful." After that, he inserted the key into the keyhole, fiddled with it a few times, and the lock opened with a "click" sound.

They opened the door and came to the rooftop. There was a barbed wire fence between the first unit and the second unit. It was about two meters high. The man could climb up with a slight jump, and then jumped to the rooftop of the first unit. The slightly more powerful woman It can also be done. If you use something like a ladder, it will be easier to climb over the barbed wire. Wang Limei used this trick to prove that she was not present.

They immediately returned to the Criminal Police Team, opened a summons, and arrived at Wang Limei's home. Wang Limei was stunned for a moment when she saw the summons in their hands, then signed it and followed them back to the Criminal Police Team.

Wang Limei sat anxiously in the interrogation room, sweat dripping down her forehead slowly like raindrops. Jiang Yiming asked: "Wang Limei, we have found enough evidence to prove that you participated in the murder of Liu Bangbang. You must confess to us the crime process." , strive for leniency.”

Wang Limei asked: "What evidence do you have?"

"First, there are a lot of Liu Bangbang's fingerprints left on the balcony and exterior walls of your home. How do you explain this? Second, the right foot of your air conditioner bracket has been corroded by a strong corrosive; third, what are you doing? At 22:8 that night, you entered through the gate of the second unit, went to the rooftop on the 8th floor, climbed over the barbed wire fence, and entered your own home, because your fingerprints were left on the padlock on the small door on the [-]th floor of the second unit." Jiang Yiming His tone was stern, and his eyes shot towards Wang Limei like arrows. Wang Limei quickly lowered her head and avoided his gaze.

After a long time, Wang Limei raised her head, took a deep breath and said, "Yes, I designed to kill that beast."

"Tell me about the process."

"He deserves death. He forced me to commit adultery with him. He had something to do with me. In order to get rid of a lifelong nightmare, I thought for a long time and finally figured out a way to make the police think he committed suicide. I I bought corrosive from the market and corroded the right leg of the air conditioner bracket again and again. When I felt it was almost done, I asked him to come to my house for a tryst at 7pm on July 11. I told him that my husband was going to Xi'an for a business trip. After sending Weng Yuan back to Longkou Community halfway, he entered the community through the gap in the wall, then entered the gate of the second unit, went to the 10th floor, used the master key purchased online to open the padlock on the rooftop door, climbed over the barbed wire fence, and entered quietly I didn’t dare to turn on the lights in my own home for fear of being seen by others. Liu Bangbang came to the downstairs of my house as scheduled. I opened the remote control lock and let him in. I met him at the door and told him: If you want to get me, you must After a small test, he obeyed my arrangement and came to the rooftop. I asked him to climb up the guardrail to prove his bravery. At first he was unwilling because he was afraid that I would push him downstairs, but I laughed at him. Cowardly, I left him and prepared to go home and shut him out. I was leaving as I said this. At this time, he called out from behind me. Unexpectedly, he had climbed up the guardrail. I pretended to be heartbroken and told him to come down quickly. , because my goal had been achieved, he jumped off the guardrail and carried me into the bedroom. When he and I were sleeping on the bed, we suddenly heard a loud knock on the door. I said to him: My husband didn’t know why he suddenly came back. We were home. If he knew, he would kill us both. I quickly told him to put on clothes and hide on the balcony. He had no choice but to hide on the balcony. My 'husband' came in and noticed the look on my face. No, I suddenly became suspicious and looked for people everywhere. Liu Bangbang was afraid of being discovered by my husband, so he had to hide on the air conditioner. As a result, he fell down and died. In fact, this was not my husband, but a migrant worker I hired with money. I gave him He paid 8 yuan and pretended to catch an adulterer. At this time, my husband should be on the speeding train." "What's the name of that migrant worker? What's his phone number?"

"I don't know. I found him at the entrance of Liangcun Village. I asked him to come to my house on time and knock on the door. I also taught him how to call my name and pretend to be angry. I didn't leave him a phone number, and he didn't leave a phone number either. I, I am afraid that if you find him from the call records, I will pay him 500 yuan in advance, and after Liu Bangbang falls, I will pay him another 500 yuan and tell him to leave quickly."

"What's that migrant worker's last name? What does he look like? How old is he? What's his accent?"

"He said his surname was Qin, that he was tall and thin, about 40 years old, and that his appearance and body shape were somewhat similar to my husband's. I almost searched all over the provincial capital before I found someone who was somewhat similar to my husband." Wang Limei vomited. A breath of relief.

Jiang Yiming handcuffed Wang Limei, and Lu Yingying escorted her to the police car and went to Liangcun to find the person Wang Limei said.

Liangcun is a large suburban village with a dense population, complex terrain, and a mixed bag of fish and dragons. It is a large suburban village with extremely poor public security. More than 2 outsiders live here. It is a center for robbery, prostitution, and drug trafficking. It is also the biggest headache for the municipal government and the municipal bureau's security department. , is a tumor in Yangtze City, but it cannot be removed.

The crime team came to the intersection where Wang Limei said and questioned hundreds of migrant workers gathered there. They all said they did not know the man named Qin. Wang Limei said that he must have escaped after Liu Bangbang fell from the building.

Several of the migrant workers said there was a migrant worker named Qin, but they didn't know if he was the person they were looking for. Because Wang Limei could not accurately describe Qin's appearance, they had to take Wang Limei back to the criminal police team to have a portrait of him.

Lu Yingying printed 1000 cooperative investigation reports to search for the whereabouts of Qin migrant workers across the province, and posted information online. If anyone provides clues to the police, she can earn bonuses.

However, after half a month, there were no clues about Qin migrant workers. The crime team suspected that Qin migrant workers were fabricated by Wang Limei, and that there was someone else who really assisted her in murdering Liu Gangbang, maybe her friend, maybe Weng Yuan. , in order to protect her friends, or Weng Yuan, she lied.

Jiang Yiming called the director of the detention center and asked Wang Limei how she was feeling inside.The director said she was calm and at home.This made Jiang Yiming more suspicious of her, but how could we prove that Wang Limei was lying?He thought about the polygraph.

6. Behind the scenes design

The use of polygraphs can cause a certain amount of psychological pressure on suspects. Combining policy education and the use of evidence and other methods can prompt the suspects to break down their psychological defenses and confess the problem or the truth. When using the polygraph, the polygrapher will repeatedly explain and emphasize the test. The scientific, objectivity, and impartiality of the lie detector, and the suspect's sense of mystery about the lie detector, make him feel that the lie detector is sensitive and cannot be deceived, and he is worried that if he lies, he may be discovered on the spot, thereby aggravating the situation. Get rid of psychological pressure and tell the truth.

However, polygraphs are only effective on suspects with average psychological quality and have no effect on suspects with strong psychological qualities. Many spies and highly intelligent suspects can escape the polygraph and mislead the police in the direction of their investigation.
