Wang Chao turned his head to look at Jiang He, and then looked at the busy criminal police downstairs. On the twelfth floor, the people on the ground became black spots under the street lights.

He leaned against the railing: "It's obvious, it's easy to guess."

"I don't understand." Jiang He was honest.

Wang Chao took out a pack of cigarettes from his pocket, lit one, and handed it to Jiang He.

Jiang He waved his hand: "Smokers are 23 times more likely to develop lung cancer than non-smokers. Ninety percent of lung cancer patients are smokers. So according to the probability, smoking is not good for the body. To a certain extent, it affects the rationality of our thinking logic and causes confusion, as well as drugs and alcohol, so I never smoke or drink."

Hearing Jiang He's words, Wang Chao laughed and said while smoking: "The longest-lived person in China has smoked for a lifetime, and still lives well. Some people never smoke in their entire lives, and they will die if they fall on the road. I can't stand up anymore."

Wang Chao blew a smoke ring in the air: "The latitude and span of life are too long, can you calculate a clear probability of how long you can live?"

"No." Jiang He said firmly: "There are too many interference factors."

Wang Chao's cigarette butts flickered in the dark environment, and he said while smoking, "So life is an uncertain thing. Are you tired of living so tensely? Smoking is indeed harmful to health. But you can numb yourself, but ordinary people like us can only numb ourselves by cigarettes."

Jiang He still didn't understand: "Paralyze yourself, what do you mean?"

But Wang Chao didn't answer: "Speaking of Li Weiyi, why he committed suicide is obvious. He has lost everything, his wife and wife are dead, and he still owes a lot of debt. What's the point of living alone?"

"Are you going to commit suicide if you lose everything?" Jiang He really didn't understand.

Wang Chao looked at the traces left on the floor again, and crushed the cigarette **** on the railing: "After coming out of the Public Security Bureau, Li Weiyi walked all the way here along Jinlun Road. He may have found many apartment buildings, but not one. The building was open until he came here and went up to the twelfth floor and jumped off the top floor."

The subsequent surveillance video also proved this, Li Weiyi did come here alone.

In the police station.

Jiang He and Wang Chao watched the surveillance video five times, including access to nearby surveillance video records. It can be clearly seen from the video recording that after leaving the Public Security Bureau, Li Weiyi did not communicate with anyone. He came all the way to the community, and then committed suicide by jumping off the building.

But on the way, Li Weiyi once took a call, and the call time was forty-two seconds.

"Where's the calling card?" Jiang He looked at Wang Chao.

"I have called back the phone just now. The number is an out-of-town number. It is a female, about forty or fifty years old. She said that she did not call anyone during that time." A technician pointed out He pointed to the mobile phone on the table and said, "Through our investigation, we found that the signal came from Longcheng, which may be signal interference."

"However, there is a number that has made many calls in the past few days, with hundreds of calls. After our investigation, we found that the call was from his company. We have informed the company about Li Weiyi's basic situation." That The technical staff continued.

Jiang He nodded and asked, "With a talk time of 42 seconds, ordinary people, on the premise of a sentence of a certain length and a moderate speed of speech, can speak a sentence in about four to five seconds, that is, two people. There are eight to ten sentences in the conversation, if there is a problem with the signal and the line is connected, does the person who made the wrong call need to say eight to ten sentences?"

"Can you find out the contents of the call?" Jiang He asked.

The technician shook his head: "Even the most powerful people in the world can't do it, unless wiretap monitoring is carried out in advance, otherwise..."

The technician waved his hand.

"Is this important?" Wang Chao looked at Jiang He, he didn't understand what Jiang He wanted to do.

Jiang He waved his hand: "It's not important, but I want to figure it out."

"The autopsy results are here."

A voice came from outside.

Xu Yiman came to the Public Security Bureau, and everyone was here, Xu Yiman said: "The deceased did not have any scars other than the high fall injury. The scars on Li Weiyi's body were all caused at one time, so the cause of death can be determined. It was a fall from a height, the specific cause of death was internal organs failure, and the time of death was 9:30. However, as for whether he jumped off himself or someone else pushed him down, I don't know."

"Suicide." Wang Chao closed the file: "There is no doubt this time, Jiang He?"

But no one answered.

"Jiang He?" Wang Chao raised his voice, "Where's Jiang He?"

But there are still traces of Jiang He in the hall.

"Where did Jiang He go?" Wang Chao asked the detective present.

No one knows.

"So many eyes didn't see Jiang He leave?"

Wang Chao questioned everyone, but no one answered.

People's attention has always been important. When Xu Yiman walked in, Jiang He had already stood up. When everyone was paying attention to Xu Yiman's autopsy report, Jiang He had already walked out of the room. At this moment, Jiang He had just come out of the gate of the Public Security Bureau. He walked straight down a dark path and left without looking back.

As he walked, he inserted a SIM card into his phone.

Reboot, the card is ready to use.

Jiang He made a call.

"That phone card is gone!"

When Wang Chao ordered everyone to continue to work, the technical staff suddenly shouted.

"What?" Wang Chao asked.

The technician replied, "It's Li Weiyi's phone card."

"His uncle's Jiang He."

Wang Chao couldn't help cursing.

He started to call Jiang He, but no one answered.

And Jiang He's call was also unanswered. There was a notification from the microphone that it had been turned off, and Jiang He realized that this was not an easy matter.

A few seconds later, a phone call came. Jiang He looked at the name in the address book. It was Li Weiyi's boss.

"Hello?" Jiang He said.

"Hello, I'm Manager Zhang of the Marketing Department of Shihai Rubber Factory." A voice came from the opposite side: "Are you a policeman?"

Jiang He didn't hesitate: "Yes, you have something to do."

Manager Zhang said: "Li Weiyi is under my control. After our consideration, we decided to give 30,000 yuan to Li Weiyi's family. We know the situation of his family. He just paid back the money for joining the company recently. There may be no savings at home, and this is our reward for Li Weiyi's hard work. It's just that we called his wife, but his wife didn't answer the phone."

Jiang He distilled a key message in a lengthy paragraph.

He opened his mouth and asked, "Wait a minute, I have a question for you. You said just now that Li Weiyi still owes money to the company. What kind of thing do you mean?"

Manager Zhang replied: "It was almost three months ago that due to Li Weiyi's work mistakes, the company lost 130,000 yuan. According to the regulations, Li Weiyi personally repaid the 130,000 yuan. After a period of time, Li Weiyi paid back the money. We know that Li Weiyi still has a mortgage and an old man at home. But work is work, and there is nothing we can do about it. "

But Jiang He had heard Li Weiyi's confession, and Li Weiyi did not say that he had paid back the 130,000 yuan.

As Jiang He walked forward, he continued to ask, "Wait, are you sure it was Li Weiyi who paid it back?"

"Yes." Manager Zhang replied.

"Are you sure?" Jiang He asked again.

"Sure." Manager Zhang replied.

"Really sure?" Jiang He asked again.

Manager Zhang was silent for a short while, and then he said again: "By the way, it is the money sent by Li Weiyi's wife He Huijuan, but since it is the money sent by her wife, it must be what Li Weiyi meant. Right. By the way, if you can contact He Huijuan, let He Huijuan come to get the money. We are also very sad about Li Weiyi's death. I don't know if you can tell me, how did Li Weiyi die? "

This is why Jiang He is reluctant to believe witnesses, because people are often not responsible for what they say.

But Jiang He finally understood why He Huijuan took out all the money transferred to her and her own savings. Jiang He finally understood why the police did not find the 130,000 yuan in her house, because the money was used by He Huijuan To repay the loss caused by Li Weiyi.

But what Jiang He didn't understand was why He Huijuan didn't tell Li Weiyi if He Huijuan clearly paid back the money Li Weiyi owed. After a little thought, Jiang He had a 60% probability that the reason why He Huijuan didn't tell Li Weiyi about this was because she didn't want to expose her affair.

It was nearly three months ago that Li Weiyi owed 130,000 yuan, He Huijuan's alumni meeting was held two and a half months ago, and He Huijuan's affair with Feng Bin began two months ago. During the period of cheating, two sums of money entered He Huijuan's account, one of 50,000 and the other of 30,000, plus He Huijuan's own savings, which was just enough to make up 130,000.

Jiang He's brain told Jiang He a piece of information, if all this is a coincidence, the probability is only about ten percent. It's not that things with low probability can't happen, but Jiang He has to figure out whether it's a real coincidence or someone deliberately contributed to the result of this low probability.

"Hello, hello? What happened, officer, officer, are you still over there? Hello, hello?"

Seeing that there was no movement on the other side, Manager Zhang couldn't help shouting.

During the time Jiang He was thinking, he kept hearing a voice interrupting his thoughts. He looked at the mobile phone in his hand, put it in his ear and said quickly, "No need, this family is dead."

With that, Jiang He hung up the phone.

Manager Zhang listened to the busy tone on the other end of the phone, and he was in a daze for a long time. He had never seen such a direct police officer, nor had he heard such icy words.
