Serious Crime Unit 1

Chapter 164 Accidental Death (4)
Another characteristic of pine boards is that there are a lot of knots at the fracture points. The knots are the weakest link in the pine board to withstand pressure, so it is easy to break. The murderer carefully planned to choose such a board.

Xiaoke took photos around the formwork pile, while Wu Jiang extracted the footprints. There were nearly 30 types of footprints, which were confusing and numerous. The footprints extracted in this public place where people come and go are not very meaningful, but the work must be done in a thorough, meticulous, patient and serious manner. It is a quality that must be possessed at the survey site.

After an afternoon of investigation, they finally called it a day and extracted physical evidence such as cigarette butts, hair, footprints, saliva, and fingerprints.

Wu Jiang asked Chi Yang to call the workers who were unwinding the planks. Chi Yang made a call, and the workers soon came to the seventh floor. Wu Jiang took a look at him: This is a typical migrant worker, over 40 years old, with a carved face. He has deep wrinkles and is as dark as an African. He looks honest, vicissitudes of life and perseverance.

"What's your name?"

"My surname is Wang, and my name is Wang Shuli."

"You were the one who put this pine board on the scaffolding as a scaffolding board, right?"

"Ah."

"Who told you to do this?"

"It's Manager Chi."

"Why didn't you take another formwork instead of this knotty pine board?"

"I saw that the pine board was wider than other templates, relatively new, and strong and durable, so I took it."

"But this pine board has a lot of scars and is easy to break. Haven't you thought about this?" Wu Jiang looked at him with sharp eyes.

"I didn't think so much... It's all my fault, it's all my fault. If it weren't for Mr. Zhou, he wouldn't have fallen. I'm guilty. You can arrest me and go to jail." He lowered his head, not daring to look at Wu Jiang.

Wu Jiang understood that he did not look like a murderer. This murderer had careful thinking, an intelligent mind, calm words and deeds, and was able to control the overall situation. "Do you know who put this pine board on the formwork pile?"

"I don't know..."

Wu Jiang thought: Let Zhou Shan step on the pine board, but not let others step on it. This shows that the murderer knew that the pine board could not bear Zhou Shan's 91 kilograms of weight. However, this would have to go through dozens or even hundreds of tests, otherwise You will accidentally kill others, but you will steal the chicken but lose the rice.In this case, he must buy a lot of knotty pine boards and take them home for testing.

Then, the murderer should live alone, and he is more likely to live on the first or second floor, because it is difficult to move pine boards in high-rise buildings and there is a risk of being witnessed.

Wu Jiang asked Chiyang if there were any monitors installed at the construction site?Chi Yang said that only two gates have monitors.Wu Jiang brought a month's worth of surveillance hard drives back to the criminal police team and asked his colleagues in the peripheral team to help check for anyone suspicious.Wu Jiang doesn't have much hope of finding the suspect in the surveillance video, because his opponent's criminal IQ is so high that even if he is moving pine boards to the construction site, it is impossible to pass through the two gates. The gates not only have monitors, but also three security guards. 3 hours guard. The construction site of No. 24 Middle School is nearly 24 acres. The fence is hundreds of meters long and not high. You can enter the construction site from anywhere.

One thing puzzled Wu Jiang: Chi Yang said that very few Zhou Shan went up to the scaffolding to watch workers working. As the president of the company, there was no need to do everything in detail, but why did he suddenly go up to the seventh floor on a whim to watch workers laying bricks?Wu Jiang is an atheist and does not believe in heresy that has been planned in advance.

In order to clarify this problem, Wu Jiang, Xiao Ke and Lu Yingying came to the headquarters of Tianzao Company to find Secretary Yang. After meeting them, Secretary Yang was enthusiastic but absent-minded, as if he was still immersed in the sadness of Zhou Shan's death.

After the two parties sat down, Wu Jiang asked: "Secretary Yang, you are Zhou Shan's personal secretary. You know a lot about Zhou Shan's situation best. Does Zhou Shan usually go up to the scaffolding to watch the workers laying bricks?"

"Very rarely. I have been with the company for 8 years. I only saw Mr. Zhou on the scaffolding once last summer. Of course, I am not his shadow. I cannot follow him at any time. I don't know if Mr. Zhou will go on the scaffolding during other inspections." Yang The secretary adjusted her glasses. Her skin was white and smooth, and her nose was high, like a porcelain beauty.

"Do you know why Zhou Shan went to the seventh floor?"

"Mr. Zhou didn't say anything, but when I saw Mr. Zhou standing on the ground and watching the workers laying bricks on the seventh floor, he frowned slightly. Then he thought for a while and then told Chi Yang that he wanted to go up to the seventh floor to have a look, and he didn't let Chi Yang. Yang, I think it may have something to do with Chi Yang... One more thing, of course, this is just my guess. Mr. Zhou may be dissatisfied with the workers' work, so he wanted to go up and talk to the workers, because we pay on a daily basis. Remuneration, 200 yuan a day.”

"Why doesn't Zhou Shan talk to Chi Yang if there is a problem?"

"Mr. Zhou may think that the workers are not working hard because of Chiyang. In the past, Chiyang was suspected of arrears of workers' wages. As you know, it is not easy to recruit workers now, especially plasterers." After Secretary Yang finished speaking, he stood up to help them. Fill the cup with water.

"Secretary Yang, how is the relationship between your Vice President Liu and President Zhou?"

"It's possible. I didn't realize there was any sharp conflict between them. Of course, it's inevitable for Vice President Liu and President Zhou to have disagreements when making major decisions." "Why are you so eager to start work? After all, Zhou Shan's body is still cold. "

"Oh, that's it. The contract we signed with 24 Zhongli stated the completion time of the project. If it exceeds half a month, it will be considered a breach of contract and a fine will be imposed."

"Can you give us the contract to look at?"

"The contract was originally kept in my safe and was handed over to Vice President Liu yesterday."

"Okay, you call Vice President Liu and ask him where he is? If he is in the company, we will go over and talk to him."

Secretary Yang took out his cell phone from his bag and made a call, explaining the situation.After Secretary Yang hung up the phone, he said to Wu Jiang: "Vice President Liu is in the office and he agrees to see you."

They came to Vice President Liu's office. Vice President Liu knew Wu Jiang and was very enthusiastic towards them. There was no trace of sadness on his face. Wu Jiang felt that he was unkind.

Ask him why he is so eager to start work?His rhetoric was similar to that of Secretary Yang. Wu Jiang asked him to show him the contract signed by No. 24 Middle School.Vice President Liu opened the safe, took out the contract and handed it to Wu Jiang to read. The contract had a total of 12 pages and was written in great detail.Wu Jiang asked Vice President Liu to directly find out the items that required fines for breach of contract.

Vice President Liu took the contract and flipped down to page 9, where he found Article 4, which stated the completion time of each project and the penalty for delay.Wu Jiang watched it carefully. After reading it, he felt that there was no problem. He returned the contract to Vice President Liu, then said goodbye to Vice President Liu and returned to the police force.

Wu Jiang pondered in the car: Who is the suspect?How can we find out the direction of investigation?After much deliberation, I felt that Vice President Liu was still suspected, because the murderer was very familiar with Zhou Shan's situation. If it wasn't someone around him who did it, how would he know that he would go to the construction site the next day?How do you know Zhou Shan will be on scaffolding?

5. The suspect fled
What prompted Zhou Shan to build scaffolding?This is a core issue. As long as you find out this issue, you will get twice the result with half the effort.

Investigating the source of pine boards is also a direction. There are not many pine boards with knots in the timber market, because merchants rarely buy pine boards with knots. Under normal circumstances, smart merchants will put the knotted pine boards when purchasing. The pine wood is picked out and let the manufacturer handle it. However, this is not always the case. Some merchants cannot verify each one when purchasing from the manufacturer, so they purchase unified goods.

The investigation was divided into two groups. Jiang Yiming and Xiao Ke went to the Nanmen Timber Market; Wu Jiang took Lu Yingying to the construction site of No. 24 Middle School. Jiang Yiming used to arrange Xiao Ke and Lu Yingying to go together because they are both young people and may have more contact opportunities. They fell in love for a long time, but every time either Xiao Ke was unwilling or Lu Yingying was unwilling, because they often bickered when they were together and seemed to be fighting to the death.Therefore, when Jiang Yiming grouped into groups, he separated the two people.

Jiang Yiming and Xiaoke came to the Nanmen Timber Market. The market is very large, covering an area of ​​more than 100 acres, with more than 300 shops. It is the distribution center for all the timber in the city.As soon as Xiao Ke walked into the market, his head was pounding. It would take ten and a half days to visit each house. Jiang Yiming saw Xiao Ke's thoughts and said to Xiao Ke: "It doesn't matter. Let's take our time. Maybe we are lucky." , you’ll find what you’re looking for quickly.”

Xiao Ke naturally didn't dare to say anything. It had been five years since he was transferred to the Municipal Bureau's Criminal Police Team. He knew that criminal investigation skills were not the most important thing in being a criminal police officer. What was important was the perseverance and the will to never give up. As time went by, naturally Everything will fall into place.

The two of them walked into a shop called Acacia Tree. The boss thought they were customers and came up to greet them. Jiang Yiming took out his police ID and said he was here to investigate the case.The boss became even more enthusiastic. He invited them into the office, turned on the air conditioner, and personally made tea for them. The boss was a detective fanatic. He could tell Jiang Yiming's rank by looking at the rank on his police officer's certificate.

"Captain Jiang, please have tea."

"Thank you...we would like to ask you about some information."

"It's my honor to assist you in handling the case. I will tell you everything I know!" The boss's expression was a bit exaggerated, as if he was very excited. Although the boss is over 40, he is not an age that easily gets excited.

“What do you do with knotty pine boards?”

"Usually get rid of it cheaply."

“Are there many knotty pine boards?”

"There are many, almost every board has knots, it's just different sizes. If there are no big knots, customers will accept it, and only 1% or even less will not accept it."

Jiang Yiming pulled up the photo of the pine board that killed Zhou Shan from his mobile phone and showed it to his boss. The boss looked at it for a while and was a little confused.Jiang Yiming said: "Are there many pine boards with such knots? Are you disposing of them cheaply?"

"Very few, if there are more, we will return the knotted boards to the manufacturer."
