Serious Crime Unit 1

Chapter 128 The mystery of falling from a building (11)
Jiang Yiming and Xiao Ke also had preliminary results in their investigation. They asked Liu Bangbang's employees and friends. Most people said that Liu Bangbang was a good person, but two people said that he was ruthless and extremely lustful, and some people said that Liu Bangbang was a good person. Being secretive means not speaking ill of the dead.

Jiang Yiming listened to Wu Jiang's report and read Wang Limei's transcript. He felt that it was impossible for Wang Limei to send her husband to the train station to take the 11 o'clock train after dinner, because it took nearly four hours to leave the train. Who would do it so early? What about wandering the streets instead of staying at home and enjoying the coolness of the air conditioner?He judged that this was a murder case and must be investigated in depth to give justice to the deceased.

Because Wang Limei is the most suspected of murder, what she said needs to be confirmed.

Through investigation and review of the surveillance video of Longkou Community, it was found that Wang Limei and her husband Weng Yuan left the community together at 19:10 that night. Weng Yuan was holding a small luggage bag in his hand, and then Wang Limei and Weng Yuan did not return. Wang Limei did not enter the community until 12 a.m. on the 1th and returned home. This is consistent with what Wang Limei said.

Wu Jiang and Xiao Ke came to the small store Wang Limei mentioned and asked the salesperson if Wang Limei and Weng Yuan had been to the store to buy anything that night.The salesperson looked at Wang Limei's photo carefully and said that she and Weng Yuan had indeed bought mineral water and apples at about 20 o'clock, but this could not rule out the suspicion of Wang Limei and Weng Yuan.

They came to the train station and called up the ticket gate where they went to Xi'an that night. The video showed that Weng Yuan entered the ticket gate and then got on the 23:[-] train bound for Xi'an from the platform. Weng Yuan did not get off the train until the train started.They called up all the surveillance videos in the train station square, but Wang Limei was nowhere to be seen. Weng Yuan slowly walked into the square from the station road, and then rushed to the waiting room.

Why didn't Wang Limei send Weng Yuan into the waiting room?Could it be that she had something to do and left Weng Yuan halfway?If so, where would she go?Could it be that Wang Limei had an affair and had a tryst with her lover?For such a beautiful woman, suitors will surely flock to her.

4. Major Discovery

Jiang Yiming and Xiao Ke came to the security room of Longkou Community and asked how many entrances and exits there were in the community?The security guard said there are three entrances and exits, namely the west, south and north gates.Jiang Yiming asked if there were any other entrances and exits. The security guard said that because the community occupies a large area and the east side is close to the highway, the developer at that time did not set up a gate on the east side. Some residents who wanted to stay close to the distance demolished the east wall. Open a gap, the height of the gap is about 1.5 meters, and adults, except children, can enter at any time.

After Jiang Yiming heard this, he felt that it was not meaningful to check the surveillance videos of the west, south and north gates.If Wang Limei murdered Liu Bangbang, then why did she and Weng Yuan go out at 7 pm on July 11 and did not return to the community until 7 am the next day?They watched the surveillance video of that night more than a dozen times. There were 1 people entering Building 9. They verified all of them one by one. There was no suspicious person, even if Wang Limei dressed up as a man and entered, it would be impossible.

Jiang Yiming felt that it was necessary to investigate the air conditioner in Wang Limei's home. At that time, the photos were taken of the air conditioner and bracket from top to bottom, not from bottom to top. They had repeatedly looked at the photos of the bracket and found nothing. They wanted to She would take pictures from bottom to top after two days. However, Wang Limei had already hired someone to replace the bracket of the air conditioner the next morning. Of course there would be no problem with Wang Limei doing this. Her reason was: if it suddenly winds or rains, The other leg of the air conditioner bracket may be blown off. If the air conditioner falls and hits someone, the consequences will be disastrous.

There are mountaineering equipment in the storage room of the criminal police team, which are specially used for high-altitude surveys. Although the mountaineering equipment has not been used for many years, it is a lot of mountaineering equipment imported from Germany. It is very strong and easy to use. Jiang Yiming called Xiao Ke and asked him to put it down. This set of mountain climbing equipment was sent to me.

Ten minutes later, Xiao Ke brought the climbing equipment. Jiang Yiming handcuffed the stainless steel buckle to the guardrail and prepared to hoist it to Wang Limei's air conditioner. Xiao Ke volunteered and said that it would be safer for him to do the job. Jiang Yiming pushed the boat and gave Xiao Ke a opportunity to perform.

Why not just knock on Wang Limei’s door and transition to the air conditioner from her balcony?The security guard Wang Limei was at work at this time, Jiang Yiming firstly did not delay her work; secondly, he did not want to alert others. In the absence of any doubts or evidence, he tried his best not to disturb others. This is a habit he has developed over the years.

Xiao Ke put on his shoe covers and gloves and hoisted it to the air conditioner. He observed carefully that the new installer might be worried that the old bolt holes could not lock the bracket. When installing the new bracket, he moved the bolt holes 10 centimeters to the left. , so it is 10 centimeters away from Wang Limei’s balcony, and the marks of the old brackets are clearly printed on the wall.Xiao Ke found that the wall next to the seal was particularly dirty, as if there was some thick liquid adsorbed on it. He kicked off his feet and swayed to another air conditioner, carefully observing the color of the wall next to the bracket. , I found that there wasn’t that much dirt sticking to the wall.

Xiao Ke swung back to the air conditioner next to the balcony, took out a knife from the tool bag hanging on his waist, scraped off some of the dirt on the wall next to the old bracket, and put it into the evidence bag.He lowered himself 1.5 meters and stared at the top of the air conditioner. He found many fingerprints and footprints. He took out the tool, extracted two footprints and several fingerprints, and then climbed up the rope to the rooftop.

After laboratory testing, it was found that the main component scraped from the wall of the old air conditioner bracket was iron trioxide, which is a strong corrosive. The fingerprints and footprints on the air conditioner were unknown and they determined that they belonged to the installer.

Why is there strong corrosive on Wang Limei’s wall?This is someone spraying a highly efficient strong corrosive on the wall. This person is not trying to corrode the wall, but to corrode the bracket of the air conditioner!Who is this person?Why do this?
In order to find out who the owner of the fingerprints on the air conditioner was, Jiang Yiming and Wu Jiang came to Wang Limei's house again and asked her to take them to the installer.

Wang Limei said: "I have no time. After dinner, I have to rush back to the company to work overtime, otherwise my boss will fire me."

Wu Jiang was a little annoyed and said sternly: "Miss Wang, we suspect that you were involved in the murder of Liu Bangbang. If you want to clear your suspicion, you can only come with us to find the installer."

"You think I murdered Liu Bangbang, please provide evidence, and I will naturally bear all the consequences." Wang Limei frowned angrily, turning from a beautiful woman to an ugly woman.

"Okay, Miss Wang, since you are not free, I won't force you. You just need to tell me where you found the installer?" Jiang Yiming asked softly in order to ease the atmosphere. "Under the viaduct in the East Ring Road, there are a large number of temporary workers waiting for work." Wang Limei's face turned from gloomy to clear.Jiang Yiming glanced at Wu Jiang and signaled him to leave. Wu Jiang seemed to leave Wang Limei's house reluctantly.

The viaduct in the East Ring Road is not far from Longkou Community, less than one kilometer. They drove to the viaduct. There were many migrant workers squatting below and playing cards. Some squinted their eyes and took a nap, and some looked up into the distance, hoping that employers would come. Looking for someone, when they saw the two of them getting out of the car, they thought business was coming. They dropped their playing cards and gathered around them. Wu Jiang asked, "Which of you knows how to install an air conditioner?"

"I will..." Three people stood up. Jiang Yiming showed his ID and said that he was from the criminal police team and that he was investigating a case and needed their cooperation. After hearing this, the three people turned around and left like deflated rubber balls.

"Hey, don't leave. There is a reward for providing clues to the police to solve the case, which is enough for you to earn a month's salary."

After hearing this, the three people immediately turned around and asked Jiang Yiming with a smile, what help did Jiang Yiming need from them?
Jiang Yiming pulled up Wang Limei's photo from his mobile phone and showed it to them. After they looked at each other, Jiang Yiming asked, "Do you know her?"

"I know her. She is the hostess of Room 9, Building 801, Longkou Community." A nearly 40-year-old man took a step forward.

Jiang Yiming called him to the car and asked: "When you installed the bracket for Wang Limei, what was the difference between the two feet of the old bracket?"

"I didn't pay much attention. It seemed that the left leg of the stent was newer than the right leg. At that time, I muttered to myself: Why is the original stent so inferior? It is much worse than the stent I brought."

“Where’s the old bracket?”

"Sold."

"To whom?"

"Boss Lin from the Xinsheng Recycling Station."

"Take us together to find Boss Lin."

"No, I still have to take over the job."

"We will only delay you for an hour at most. Let's do this. I'll give you 50 yuan."

He took the 50 yuan handed to him by Jiang Yiming and smiled.

Jiang Yiming took the opportunity to rub his fingerprints and footprints.

After finding Boss Lin, he said that he had sent the old bracket to the ironworks. The two of them rushed to the ironworks. With the cooperation of the director and workers of the ironworks, they spent a whole afternoon and finally found it. That old brace.

After testing by a laboratory technician, it was found that the iron bars, screws, and screw heads on the right foot of the old bracket were corroded by strong corrosives, which caused Wang Limei's air conditioner to break after being stressed. It is obvious that Liu Bangbang's footprints on the rooftop guardrail were deliberately made by others. The purpose of printing it was to create the illusion that Liu Bangbang fell from the rooftop, thereby confusing the police. In fact, Liu Bangbang should have fallen from Wang Limei's air conditioner. This was a perfect murder case!The only pity is that there are no Liu Bangbang's footprints on Wang Limei's air conditioner, because Liu Bangbang's footprints have been completely covered by the installer's footprints.How to find evidence that Liu Bangbang fell from the air conditioner is the most important issue for the crime team at the moment.
