Forensics

In the early morning, Penang City Council.

The city outside was already pitch black. In the police office, Bai Meng found some photos and videos in Wei Sen's cell phone.

It contains a group photo of Wei Sen and Zhao Chuanwen, and a group photo of a Go game held by the community.There are also some pictures taken by the pension company when it was promoting near the community.

A few of them were taken as free physical examinations organized for the elderly. A doctor in a white coat was measuring the blood pressure of the elderly, and there were a few staff members standing beside them, all smiling.

Those are still normal, but the latter ones are not normal...

There is a group photo of several elderly people sitting together, opening a lunch box to eat, but an "acquaintance" appears in the background.

Bai Meng zoomed in on the picture to make sure he read it correctly.

That was the delivery man who was caught by her when they were investigating the case on the mountain at night.

Bai Meng continued to search and found that this delivery man had appeared in Wei Sen's mobile phone more than once. He seemed to often deliver food to Wei Sen and the others, and he was very familiar with them.

Bai Meng logged into the police system and called up the personal information of all the delivery workers in that area.

People generally feel that the delivery staff who deliver food to themselves are often different every time, but this is the perspective of the orderer.

In many places far from the city center, the delivery staff are relatively fixed, and even in some remote areas, there are only one or two food delivery staff.

When a customer orders a fixed restaurant, it is easier to be assigned to the same delivery person.For example, at the spot they went to today, there were only 24 food delivery staff stationed nearby.There is a high chance of meeting the same person.

Bai Meng quickly found the delivery man who delivered the food based on his impressions.

The man's name was Zhang Lijie.

Then Bai Meng checked the phone number of the delivery person provided to her by the delivery platform last night.

Bai Meng found out that it was not Zhang Lijie who took the order last night, but another deliveryman named Li Hong, but Li Hong didn't deliver the food to them, but Zhang Lijie did.

Probably because of this, Zhang Lijie didn't call her to explain his location.Because then his mobile phone will not display the protection number, and it is easier to see the problem.

Bai Meng speculated that it might be that the order was far away. Zhang Lijie knew that a murder had occurred nearby, so it was not difficult to guess that the orderer would be the police.He took the initiative to express his willingness to help his colleagues with this order, so he took a takeaway and came down the mountain.

Bai Meng recalled the process of arrest at night.

At that time, they were on the mountain and saw Zhang Lijie, and then Zhang Lijie fled in a hurry. At that time, her criminal police instinct forced her to chase after him.

Moreover, when Zhang Lijie was on the mountain, he moved quickly in the darkness, and quickly drilled into a small place, which showed that he was familiar with the terrain there, and it was not at all that he took the road by mistake because he was not familiar with the terrain as he said.

The guilt and panic he felt while running were real.

Bai Meng frowned and thought about it. At that time, Zhang Lijie deliberately wore the takeaway clothes inside, probably because he wanted to take the opportunity of food delivery to go up the mountain to check the situation.

And when Zhang Lijie saw them, he pulled off his clothes, and he had already thought of the excuse.

Feeling that he had discovered an important clue to the case, Bai Meng looked at the time and it was past two o'clock in the morning.She was excited and had no one to share with her, so she could only continue to investigate the case patiently.

In general cases, after suspicious points are discovered, background checks are required to restore the facts of the case.

Bai Meng learned from Gu Yanchen's usual method of analyzing cases, and began to further investigate the details of Zhang Lijie.

Zhang Lijie's family lives three subway stations away, which is the starting station of this subway.He is 49 years old and has been delivering food for several years. He is an old delivery man.

His wife is a housekeeper, and his son used to work on a construction site, but fell from the fourth floor. He suffered a work-related injury but did not receive corresponding compensation, and he was involved in a long-term lawsuit.His daughter-in-law is promoting shampoo in a supermarket, which is not considered a regular job.

In short, Zhang Lijie's family's economic conditions are not good, and his grandson has a congenital heart disease. The family has spent a lot of money to see a doctor for the child, and they are still raising money for the operation on the child.

It can be seen from the food delivery evaluation system that Zhang Lijie has been an excellent employee for several months this year.

However, food delivery people always encounter some emergencies and receive some bad reviews, some of which are from Zhao Chuanwen and Wei Sen.

Background checks are done quickly.

At three o'clock in the morning, Bai Meng went to wash his face with cold water, and continued to come back to check the clues on the day of the crime.

The surveillance video of Zhao Chuanwen's fall from the subway has already been sent.

Bai Meng watched the video of the incident and several surveillance cameras of people entering the subway entrance one by one.

In the past, this was a workload that several police officers could complete in a few days. She doubled the speed, opened four windows at the same time, and carefully checked.

At the peak station of the morning subway, although there were many people and the monitoring was blurred, Bai Meng found Zhang Lijie from the crowd. He came here by the first subway.

After getting off at this station, he didn't leave, and kept wandering in the station until Zhao Chuanwen entered the station, and he appeared not far behind Zhao Chuanwen...

When the incident happened, he was very close to where Zhao Chuanwen was standing.

In the video provided by Jiang Xiaoyi, when Zhao Chuanwen's hand was pushed down, a section of sleeve was the same color as the sleeve of Zhang Lijie's inner clothes.

Bai Meng checked Wei Sen's call records again. After Zhao Chuanwen fell off the subway at [-] o'clock in the morning, Wei Sen once ordered a takeaway breakfast. This time, it was Zhang Lijie who took the order again.

Not long after Wei Sen walked out of the community, Zhang Lijie also passed by the monitoring station.

The same person appeared at the crime scene one after another, and he is very suspected of being the murderer.

In the police office in the early morning, Bai Meng worked tirelessly all night, and she found more and more information and evidence.

Bai Meng checked it repeatedly, the logic was self-consistent, and the chain of evidence was complete.

Although this was not a complicated case, the feeling of having found the real murderer alone made her blood boil.

At six o'clock in the morning, the sun finally rose, Bai Meng got up and stretched.

She intercepted all the evidence, called Gu Yanchen, explained the situation, and sent the relevant evidence.

Gu Yanchen was woken up by her phone call.

Gu Dui, who was disturbed by Qingmeng, was not angry at all. He carefully read all the materials sent by Baimeng.

"I didn't expect you to solve the case so quickly. You did a good job! This person is very suspicious. Let's go through the procedure and arrest him. I'll go to Deputy Director Dong."

Bai Meng said energetically: "Okay!"

Gu Yanchen said again: "You did not arrest the wrong person last night."

Last night, he could feel Bai Meng's loss, and he also understood her intention of working overtime last night. This girl was very stubborn, and he didn't expect her to find the murderer.

After hearing this sentence, Bai Meng was immediately relieved, she said with a smile: "I can't embarrass my parents either!"

Gu Yanchen said: "Thank you for your hard work, don't doubt yourself, you have always been great!"

Hearing this, Bai Meng's eyes were slightly wet.

When she was young, she was still in kindergarten, and she heard the stories of her father catching bad guys. At that time, she said in a childlike voice: "I want to be a policeman when I grow up."

But my father always shook his head, and when he finished speaking, he had to say, "It's too dangerous for a girl to do this. It would be great if you had an older brother or a younger brother. It's a pity that your mother is not in good health and can't reproduce."

When she grew up, she stubbornly reported to the police academy, and said to her family with a smile: "The spirit of three generations of police officers in our family can't end with me."

But she also knows that this road is not easy to walk, especially for girls who are engaged in this industry and become a criminal policeman, they will always face many difficulties and criticisms.

She has been training hard all the time, but because of her job function, she does too many civilian jobs in the police force, so she can't go to the front line, and she always feels a little regretful.

Now, she's found a suspect on her own.

She finally proved herself.

What's wrong with girls, girls can also solve cases with boldness and carefulness.

Bai Meng filled out the arrest application with enthusiasm, and Gu Yanchen urged the leaders of the city bureau and the procuratorate to expedite the approval process.

Colleagues who got up early received the news and sent messages one after another.

Lu Yingdao: "Xiaobai, you are so awesome, you even found the murderer in one night!"

Bai Meng: "Sister Bai!"

Qi Yi'an: "Morning sister, sister has worked hard. What would you like to have for breakfast, sister?"

Bai Meng: "It's still Qian's forensic doctor. From now on, my sister will cover you, and you will get more discounts on blind dates."

After a few words in the small group, she went out and called her father.

She was afraid it would be too early, but her father picked it up in seconds, and Bai Meng just called her dad.

The old Bai on the opposite side said like a cannonball: "I know, you solved a case, and all the leaders of the city bureau were picked up early in the morning to let you go through the arrest process. This matter has come to me. This Isn't it a common thing? Which policeman has never solved a case? Still want to come to me to claim credit?"

Bai Meng was reprimanded, and she calmed down. It was really not a big deal, but she was a little bit wronged by her own father, her original excitement was suppressed, and she suddenly didn't know what to say.

But the mother on the other side snatched the phone: "Don't listen to your dad talking nonsense, just now he was bragging with Deputy Director Dong, saying that she is my Lao Bai's daughter, of course she is capable! Said that you solve the case quickly, I wish I could use a loudspeaker, Go broadcast in the yard."

After hearing this, Bai Meng felt a little better. Her father was hard-spoken and soft-hearted.

The mother said again: "Daughter, are you tired? Have you stayed up all night because of this case? You should have a good rest and eat well."

Bai Meng said with tears in her eyes, "Mom, I know."

Lao Bai took the phone again, his voice was still stiff: "Daughter, don't be proud! I'm afraid you will be proud! Go get busy, you still have to go to work!"

The tears that Bai Meng was about to shed stopped, and she let out an expressionless expression.

Lao Bai's voice softened: "Don't be proud of yourself, because...you will always be our pride."

Hearing these words, Baimeng broke his defense instantly.Her tears flowed down, but she smiled again: "Thank you, Dad."

At 06:30 in the morning, the police officers from the Municipal Bureau and the Sixth Sub-bureau went out to arrest people. They rushed to Zhang Lijie's home and blocked him before going to work.

Gu Yanchen learned that Zhang Lijie's family situation was not good from the information Bai Meng gave him.But when he arrived at the scene, he was still stunned.

It was a one-story shanty house, the house was drafty, the lighting was not good, and the toilets were all outside.

There are a total of more than 20 square meters inside, which are divided into two rooms.

Zhang Lijie's son-in-law and a child slept in the outer room, and Zhang Lijie and his wife slept in it.

Gu Yanchen led someone to knock on the door and entered the room, and the small room was suddenly full of people.

Zhang Lijie had already gotten up, he seemed to be mentally prepared and knew the purpose of these police officers here.He said, "wait for me, add some clothes."

Lu Ying urged: "Hurry up."

The police officers were afraid that Zhang Lijie would run away or resist with weapons, so they stood not far away, holding electric batons, and stared at him closely.

Zhang Lijie took out a delivery suit from the cupboard and put it on.Then he tidied up his clothes, and said to Gu Yanchen, "I'll go with you."

Gu Yanchen stepped forward to handcuff him, Zhang Lijie's lips trembled: "Officer Gu, my grandson has a heart attack, can you get me something to block it, I don't want to scare the child."

When Gu Yanchen heard this, he didn't say anything, but he still took a helmet from the side for him and put it on his hand.

Zhang Lijie used the helmet to block the handcuffs, and it looked like he was going to work.

Outside, the family members were all there, and Zhang Lijie bid farewell to them one by one.His wife turned away and secretly wiped away tears.

When he walked in front of his little grandson, Zhang Lijie knelt down and called his grandson by his nickname: "Xuanxuan, don't worry, grandpa went out with his uncles to do some errands, and he will be back soon. During the period of grandpa's absence, You have to listen to your parents carefully."

The little grandson was only three or four years old, and looked at Zhang Lijie with his eyes. He didn't know what happened to his grandfather, so he just nodded obediently.

Zhang Lijie walked out, without much nonsense, and got into the car with the police officers.

From the moment he got into the police car, Zhang Lijie began to cry and kept wiping his eyes with the back of his hand.

When he arrived at the Municipal Bureau, he was locked in the interrogation room. Facing the evidence, Zhang Lijie didn't have too many arguments, and quickly confessed.

Before, everyone did not expect that this seemingly honest and honest delivery man turned out to be the cruel murderer who killed two old people in succession.

And he was really daring, he killed two people in a row yesterday, and even dared to walk around under the nose of the police at night. Fortunately, Bai Meng discovered the connection and dragged him out.

But thinking about it carefully, he is also the person who is most familiar with the situation of those old people. He delivers meals to those lonely old people every day, which may have created grievances and emotions.

Zhang Lijie was sitting at the table. He was very tanned. There was an obvious black and white dividing line on the helmet. Under the light of the interrogation room, the gully on his face became more obvious. He seemed to have aged a few years in an instant: "Officer Gu, people All my life, I've been on the wrong track."

Gu Yanchen looked at the middle-aged man sitting opposite, and said, "Please explain the process of committing the crime."

Having said that, Zhang Lijie let out a long sigh.

"You have also seen the situation in my family. I have worked hard all my life. I was unemployed in middle age. I worked as a delivery man and got that little salary every month. But how did I know that those old people are extremely picky about my work? Yes. I was late for food delivery, they gave me a bad review, spilled the soup, gave me a bad review, the merchant put less stuff, and gave me a bad review for the delivery guy. Every month my salary will be due to their Some complaints are deducted, and promotion and salary increase will be affected.”

He babbled about some things, all because of the friction between him and those old people.

"Two months ago, it was raining heavily. Zhao Chuanwen ordered a takeaway. When I was passing by, I fell on my bicycle. My legs were swollen, my whole body was wet, and some food spilled out. I asked him, I gave him food money. Can you not complain to me? He glanced at me and took the food in my hand. He said, 'This is your job. I don't want your money. I just want my food.' Then he Turned around and left. At that time, the blood in my body was cold."

Having said that, Zhang Lijie clenched his fists.

Gu Yanchen asked: "So you killed them because of these frictions?"

Speaking of this, Zhang Lijie seemed to have returned to yesterday.

He was standing by the platform, and when he went out, his wife had just finished arguing with him.Because of lack of money, not only did grandson's operation not have to be done, but the medicine might be discontinued.

He got up too early and his head was covered. He watched Zhao Chuanwen squeezed into the crowd and stood in the middle of the front row. His back was right next to the subway, so close...

He remembered Zhao Chuanwen's indifferent face when he was talking to him...

Zhang Lijie couldn't help clenching his fists: "Yesterday morning, I took the subway to work, and when I arrived at the subway station, I met Zhao Chuanwen. At that time, my heart was full of hatred...Why, everyone is human, and his family just The demolition took so much money. I was just jealous of him! I was in a daze at the time, and I thought, I want him to die."

"I just... I just followed behind him! I deliberately mixed in the crowd. When the car was approaching, I pushed...he just...he fell. I was wearing a mask and went out among the crowd on the subway."

Gu Yanchen asked: "You killed Wei Sen later?"

"When I first arrived at the company, Wei Sen ordered an order. I think Wei Sen is a good friend of Zhao Chuanwen, and the two of them are often together. If I keep Wei Sen, he will think that I did it. I Knowing that he often went to the hill to exercise and take a walk after eating in the morning, I just kept doing it..."

After killing a person, Zhang Lijie thought that if he was found out, he would be sentenced to death anyway, so it's better to bet a big one.

And when the police came to investigate later, he was still acting in front of several police officers. The sky was gloomy, and even Gu Yanchen didn't notice at that time that his expression was different.

The suspect confessed, and another serial murder was solved, but Gu Yanchen, who was sitting opposite the suspect, did not feel any sense of accomplishment.

He did not choose to end the interrogation.

"Zhang Lijie, the criminal process you confessed is true, but you are lying about the motive of the crime." Gu Yanchen took out a stack of investigation materials and placed it in front of Zhang Lijie.

"We have asked your colleagues and checked your employment records. Although there are bad reviews, they have not affected your work and life much. Everyone said that you are a conscientious delivery worker. Moreover, you and The grievances of these old people don’t stop there.”

Gu Yanchen flipped through the files in front of him, and brought Zhang Lijie to recall together.

"Three years ago, one afternoon, Zhao Chuanwen ordered a takeaway. He suffered from heat stroke that day, and he suddenly fainted as soon as he took it in. You could have ignored this matter, but you called someone to take him to the hospital when he was sick. first aid."

The occurrence of this incident made Gu Yanchen think that there must be other reasons in the case. If Zhang Lijie was really a cold-blooded murderer, then at that time, when this incident happened, he could not have saved Zhao Chuanwen at all.

Speaking of which, Zhang Lijie was Zhao Chuanwen's savior.

Zhang Lijie pursed his lips, nodded and said: "The thing you said did happen. But it was a long time ago. Zhao Chuanwen has a bad memory, and he doesn't remember that I did it at all."

"Then let me tell you something close. At the beginning of this year, Wei Sen had a back problem and it was difficult to get out of bed. I just gave you the key to my house. You gave him half a month's food. You also helped him Take the trash downstairs."

"During the Chinese New Year in the past two years, you made a lot of dumplings yourself, and delivered dumplings to the lonely old people who often order from you. You said that you want them to feel the warmth of home..."

Zhang Lijie's eyes were wet. He gritted his teeth and said, "I didn't get any money for what I did. I didn't get anything in return from others! I treated them well, and they verbally Say thank you, but I still won't understand my hard work behind the scenes. Of course I will kill them!"

Gu Yanchen looked at him, and his voice was severe: "Even then, you are not a person who will kill at will, and you killed two people in a row."

Not many people will put it into practice when it comes to killing people. There is a huge gap between the good guys and the bad guys.

Gu Yanchen mentioned these not out of sympathy for the murderer, and a poor family is not a reason for breaking the law.He asked because he was desperate to know what was hiding behind the truth.
