Forensics

Another sunny morning, Penang Metro Line 2, Penang Science and Technology Center Station.

This is an extension of Line 2, and it is the third stop after the starting station, located at the western end of the entire city.

It's very far from the city center.But the rent is cheap enough, and the house is very new, suitable for young people who have just started working and their wages are not high.

Jiang Xiaoyi and her college classmate Zhang Xin were fooled by the agency in the first place. They graduated last year and were fed up with the expensive old houses in the city. When they saw the houses here, they felt big and spacious.

When I actually moved in here, I realized that it takes an hour and a half to go to work every day, and it takes nearly three hours to go back and forth.

Every day like this, commuting has become a kind of torment.

Today they woke up early as usual, washed and put on makeup, and hurried out, yawning as they walked down the long stairs of the subway station.

At [-] o'clock in the morning, there was a long queue at the security check and entrance of the subway. One can imagine what kind of tragic "fight" it will be.

Most of the subways are young people like them who are stuck at work, some are swiping their phones, and some are eating breakfast.

If you can't catch this train, you may be late for the next train after sitting for 5 minutes.

They passed the security check and were about to swipe their cards when an elderly man suddenly jumped in front of them.

The old man was full of silver hair, hunched over, pushing a small shopping cart, and his movements were not slow.

He squeezed Jiang Xiaoyi, and pressed the card in his hand on the subway ticket inspection machine arbitrarily: "Drip, senior card."

Jiang Xiaoyi was so angry that her nose was crooked by this behavior of jumping in line, and she rushed up to argue, "It's you again! You stepped on my foot last time, and this time you're jumping in line again!"

They knew the old man every day when they went to work, so they rushed to rush the morning rush hour, and came at about the same time as them every time.

Zhang Xin pulled her aside: "Forget it, don't argue with the old man. Let's go down quickly, we won't be able to catch up with the car later."

The old man seemed to be deaf, and he didn't hear them talking, so he walked straight into the subway.

Jiang Xiaoyi just swiped the card, and said to her best friend angrily: "You said we are afraid of being late for work, why are these old people in a hurry? Since the subway transportation is free for the elderly, they fight with us every day. This is rushing reincarnation?"

Zhang Xin spoke for the old man: "Maybe he has something urgent to do."

"After buying vegetables in a hurry, go to the park to find the old lady?" Jiang Xiaoyi still couldn't help complaining: "You don't know, last time I got a stomachache when I got off work, and I finally got a seat, but an old lady came over and forced me to sit. He told me to give up my seat. The man next to me was still sitting in the love seat, bullying the weak and fearing the hard! I gave up my seat to her, and she got off after two stops, and ran faster than a rabbit when she got off."

Zhang Xin said: "Isn't there a saying, it's not that old people become bad, but that bad people become old. We will also grow old one day, and maybe we will compete with young people for seats later."

Jiang Xiaoyi was a little discouraged: "I don't want to go to work when I think about taking the subway for an hour and a half and facing the supervisor's ugly face."

Zhang Xin smiled wryly: "We want to work hard to stay in Penang, so we have to get used to these, or you'll go back to your hometown to take the public exam."

When this topic was mentioned, Jiang Xiaoyi curled her lips: "What is the test? It doesn't matter to my family. The whole city is fighting to grab those places. It's a waste of time."

While talking, the two of them consciously walked towards the tail of the subway, where there are fewer people and it is easier to get on the train.

They walked over and saw that it was only a short while before the old man who joined their team was already standing in the middle of the front.The two of them can only stand in the back row.

Jiang Xiaoyi pouted at Zhang Xin and said, "Look, that old guy has squeezed to the front, he's really growing stronger."

This station is an aboveground station, without guardrails, yellow lines are drawn on the ground, and there are loudspeakers emphasizing not to be crowded.

Probably the car was approaching soon, and the people in the front row had crowded several layers, separating them from the old man.Jiang Xiaoyi saw that they couldn't squeeze in anyway, so she was not in a hurry.

Zhang Xin said that he should hurry up to buy a bottle of water from the vending machine, while Jiang Xiaoyi turned his back on the crowd, turned on his phone, and took a picture of his makeup.

The newly bought eyeshadow had gold glitter in it. She raised her hand and patted it down. She turned on Beauty Face and recorded for a few seconds. During this time, the subway came into the station.

The cars could be seen, and the people standing in the front row unconsciously rushed forward.At this moment, people suddenly heard a plop, followed by screams from the people in front.

Jiang Xiaoyi also heard the cry. She turned her head to look at the crowd, and heard someone say, "Someone has fallen!"

There was a creepy sound in the subway, and Jiang Xiaoyi's hairs stood on end. It was the rubbing sound when the subway train and human bones were crushed.

There was a sound of sudden brakes on the subway in the morning rush hour, and it stopped there.

Even though the driver reacted quickly, he still ran over and killed someone, blood was splashed on the platform, people in the front row retreated one after another, and some people started to run outside the subway.

"It's an old man."

"It was standing well, but suddenly fell down for some reason."

"Oh my god, it's too miserable... I guess it's hopeless?"

Jiang Xiaoyi encountered this situation for the first time, and felt that her legs were weak.

A staff member of the subway ran down immediately to check the situation.

Someone called the police, and someone shouted with a loudspeaker: "Emergency, the subway is out of service, please consciously transfer to other means of transportation."

Not only the passengers on the platform were evacuated, but even the passengers on the subway car were evacuated and got off.

People hurriedly left the subway, talking about bad luck.

Jiang Xiaoyi and Zhang Xin reckoned that they were going to be late, so they followed the crowd from the subway and took the bus to work instead.

Zhang Xin looked at Weibo while walking. During this time, discussions have already started on the Internet.

"There is an accident on the subway line [-]. The entire line is out of service."

"I heard that an old man fell down."

"Did you jump off by yourself?"

"Maybe it's because there are so many people being squeezed down, maybe the old man is dizzy himself."

Jiang Xiaoyi still felt her legs were weak and trembling until about ten minutes had passed. As long as she recalled the piercing sound, her teeth would keep touching each other.

She couldn't help but post a circle of friends.

"I'm scared to death. I happen to be at the scene of the incident on Line [-]. Please comfort me... I'm going to be late again today."

She posted the video she took in the morning, and a sharp-eyed friend immediately noticed: "The old man was pushed down!"

Jiang Xiaoyi watched the video again, and there were many people standing behind her. The old man was in the corner of the background. It can be seen from the video that a hand stretched out and pushed on the old man's back...

A homicide happened, and the police arrived as quickly as possible. The first to arrive was the nearby Sixth Branch.

The track needed to be cleaned up. The forensic doctor of the branch office first took pictures of the scene and brought up the corpse, which was placed on the platform.

The criminal policemen, who had never seen such a brutal scene, covered the old man with a white cloth without changing their expressions, and stood aside talking.

The captain of the sub-bureau, surnamed Bao, and several team members said: "Just pull up the cordon and protect the scene. Later, the criminal police from the city bureau will come to inspect the scene."

The team members on the side were puzzled: "This seems to be a small case, why did it alert the elites of the city bureau? As the saying goes, you can't kill a chicken with a butcher's knife."

Bao Tui returned to him with his arms akimbo: "Now there are new rules. After receiving the police, they are required to summarize the information and report it to the General Administration as soon as possible. This case was specified by the Municipal Bureau, so naturally they have a reason. "

Someone responded immediately: "I also heard that the Municipal Bureau has recently taken over a lot of ordinary cases. I don't know what kind of chain case they are investigating? Isn't it a good thing that they are willing to work? Anyway, we are happy to have a leisurely time."

Team Bao patted the team member who spoke on the shoulder: "What are you thinking? Later, the whole team will cooperate with the investigation and work together."

An old criminal policeman lit a cigarette at the side, "But speaking of it, the recent economic downturn has made people very angry. I feel that the frequency of police calls in the past two years has become more than before."

The team members on the side also said: "That's right, especially the elderly, suicides, accidents, homicides have increased."

Three or ten minutes later, several people from the Special Criminal Division arrived at the scene.

The subway station where people used to come and go has now been emptied, and several cordons have been blocked in all directions near the scene.Seeing them arriving, the Bao team hurriedly began to hand over.

Gu Yanchen raised his head and looked around the situation.

This is an underground train, and the platform has no guardrails.

The monitoring has been called out and sent to them.

The crime took place at the end of the subway, and the surveillance system was hung a little far away. I could only see a group of people moving around, and it was impossible to see who was holding out the hand. Then the old man swayed and fell, and the subway slowly drove over. .

At that time, there were too many people nearby, and the subway staff did not deal with it in a timely manner. They regarded the accident as an accident and let the murderer escape among the crowd.

The police released a message to find witnesses, but so far, except for a girl named Jiang Xiaoyi who contacted them, there are no other clues.

There are all kinds of messy footprints on the ground, and some are stained with blood. With so many traces, it is difficult to confirm the murderer's information.

The small trolley that the old man used to buy vegetables was also picked up, and it was run over by the wheels and turned into twists.

The corpse on the ground was covered with an improvised white cloth.

Shen Junci put on a mask and gloves and squatted down, opened it to take a look, and a strong smell of blood wafted out.

Qi Yi'an also carried the investigation box and looked at it. The corpse barely maintained a human shape, and he could only use four words to describe it as "terrible".

Shen Jun resigned: "The deceased was male, aged about 80 years old, the cause of death was the subway run over to death, let's do a physical examination first. Let's speed up the time, the subway will resume transportation later."

They rummaged through the old man's pockets and found a crushed ID card, a mobile phone with a cracked screen and a bunch of keys.

Everything was put into the evidence bag, and Bai Meng opened the laptop beside him, identified the name on the ID card, and quickly found the identity of the deceased in the system.

"The deceased, Zhao Chuanwen, was 81 years old and lived in a community near here."

After hearing this, Qi Yi'an couldn't help feeling: "Teacher, you are so amazing, the age prediction is only one year away."

Shen Junci said a little depressed: "It's actually a year behind."

Qi Yi'an: "..."

The photos were saved, the evidence collection was completed, the forensic doctors were preparing to transport the body back for autopsy, and the subway staff also began to wash the ground to prepare for the subway re-transportation.Gu Yanchen brought a few criminal policemen to the old man's former residence.

The community where the old man lives is 10 minutes away from the subway station, called Lvhe Community.

This is a new community, just built more than two years ago.

The environment in the community is good, with various flowers and trees, and there is a fountain in the atrium.

The community is a bit big. In order to understand the situation, they went around and first went to the community office located in a corner of the community.

At 08:30 in the morning, several staff members in the community had just come to work. When they heard that it was an old man in the community who fell off the subway, several staff members were surprised.

A woman called out, "Director Gao, is that the area you are in charge of?"

After hearing what they said, a middle-aged man ran over. He checked the information: "He lives here, Room 702, Building [-], Zhao Chuanwen. I still have an impression of him, and I will take you there."

While leading a few people, Director Gao introduced them: "This Zhao Chuanwen is a widowed old man in our community. His wife passed away early and has no descendants. He often comes to participate in the elderly care activities organized by the community. .”

Gu Yanchen asked: "What activities have been held in this community?"

Director Gao said: "It's nothing, it's just that there was a chorus competition before, and there was a Go competition. It seems that Lao Zhao won No.2 in the Go competition, and he also got a 500 yuan bonus."

Director Gao led them to the door, and called the unlocker to open the door.

The entire room is quite large, with a total of 140 square meters, three bedrooms, and a study.There are no electronic products at home, and there are no books or notebooks.

Bai Meng searched there, frowned and said: "All his family members have passed away, and no relatives came to identify the body."

The physical evidence accompanying the team today is Guan Haiyi. He checked around with his shoe covers, frowned and said to Gu Yanchen: "Gu team, this place is quite clean, only the old man's living traces."

Lu Ying asked while checking: "He is only one person, why does he live in such a big house?"

Director Gao leaned against the door and said: "You don't know very well. In the past, this area was all in the countryside of Penang. Zhao Chuanwen was very lucky. His family was a demolition household. He paid three for one house. He only bought one property, and the rest was paid for compensation. .”

Based on the current housing prices in Penang, that amount of money is not small.

Everyone didn't realize that this ordinary-clothed old man was actually an invisible rich man.

While scanning his fingerprints, Guan Haiyi said, "Most of the elderly have houses, and it's not normal if they don't have a house."

Bai Meng was still young, so she didn't quite understand the meaning of these words, so she raised her head and asked, "Why?"

Gu Yanchen replied to her: "The elderly have accumulated some wealth. Some people are old and single, so it is difficult to rent a house."

No landlord would be willing to rent a house to widowed and lonely people over 70 years old, even if they pay a lot more rent.

If someone dies in the house, it will become a haunted house.

This is a sad and realistic problem that young people often don't realize, but people will eventually grow old.

Zhao Chuanwen's home did not find any useful information, so Gu Yanchen asked the criminal police to take the police officers to look for it.

The objects of the search include the old man's upstairs and downstairs neighbors, the manager of the property, and the security guard at the gate.

With a white dream, he knocked on the opposite door.

It was an old woman in her 60s who opened the door. Hearing that they wanted to ask about the neighbors, the old lady frowned.

"What happened to Lao Zhao? I don't know... I saw him a few days ago."

Bai Meng asked, "When was the last time you saw Zhao Chuanwen?"

The old aunt frowned and thought for a while: "Three days ago..."

Bai Meng asked: "Who does he usually associate with?"

The old aunt was very enthusiastic, and she said all kinds of things before asking a few words.

"Lao Zhao has some good friends. They often go for walks and play chess together. One of them seems to be called Lao Wei. Why don't you ask him to see what he knows?"

Bai Meng continued: "Then what's the old Wei's name?"

The old aunt thought for a while: "I don't know, I only know that everyone calls him Mr. Wei. They seem to have met when they participated in activities together, and they also live in this community."

Gu Yanchen wrote down the name, and then he asked the old aunt, "What activities do they usually participate in?"

"It's just those activities for the elderly." The old aunt was not surprised. "There are often ones nearby. Some sell health care products, and some promote nursing homes and healthy elderly care. Every time they go, they send eggs and things. They have a group of people. When I have nothing to do, I like to queue up to participate in activities, listen to lectures, and take the opportunity to meet friends, which is the same as someone who likes to dance in the square."

Those who run classes will give some things and give some small favors to the old people.

Bai Meng reminded: "Auntie, you should also be careful, those who pull people over to deliver things are mostly liars."

The old aunt said: "I know, I still need to pick up my grandson, and there are not many. And I won't pay easily, just get something, and don't participate in any activities. My daughter and my wife look down on me. Damn, I don't have spare money to cheat them."

They asked a few more questions, and the old aunt couldn't think of anything anymore: "I'm going to make lunch, you should ask Lao Wei, every time I pick up the child, I often see Lao Wei coming to him, two The old man is often together."

After chatting with the people around them, they went back to the community management office again. Director Gao helped them check the registration booklet. After searching for a long time, they found a person surnamed Wei, named Wei Sen.

He is 78 years old, a native of Penang, and his family is also a demolition household. He lives in Unit [-], which is two rows away from Zhao Chuanwen.

This Wei Sen is a retired old teacher. Like Zhao Chuanwen, he is old and has no relatives at home.

"I'll contact him first and ask him to cooperate with your investigation." Director Gao turned around and made a phone call, "Yo, no one answered the phone. Immediately go and have a look. It's time for dinner, the leaders of the city bureau, why don't you go to have a meal first?"

Gu Yanchen made an arrangement, let the people from the team and Director Gao go to find Wei Sen, and take the people to dinner first, so that the two teams can be replaced without delaying the case.

After tossing around all morning, considering that they would still be nearby in the afternoon, they didn't go back to the city bureau, so they found a table in a nearby small restaurant and ordered food.

Bai Meng sighed: "Is this the fourth case that happened this week?"

She didn't know why Bureau Ding and Team Gu suddenly focused on ordinary cases in the city. As long as the victim was over 70 years old, they would be sent to the Criminal Investigation Team of the City Bureau for key processing.

If you don't investigate normally, you don't know that there are so many cases of elderly people dying every week.

They have handled several small cases one after another this week, and have been busy working overtime.

Those cases were small and uncomplicated.

An old man was killed by a neighbor driving a car, and a seriously ill old lady was locked at home by her niece to starve to death. The criminal forensic department also displayed a floating corpse of an old man fished out of the river, waiting to be identified.

Somehow, it seemed like the whole city had suddenly gone mad.

There are violent killings everywhere.

Killing the unarmed old man.

Gu Yanchen was drinking water at the side, he lowered his head and lowered his eyelashes and said, "This may be a serial murder case."

Lu Yingdao: "Captain Gu, don't be joking. In the case of serial killings, there are usually one or two murderers. We have investigated all these cases, and they all have their own murderers. Those people are completely out of control. I don’t even know each other.”

Gu Yanchen said: "That's why we need to find the common ground of the cases."

Bai Meng frowned: "Even if you look at these cases repeatedly, it's hard to find similarities..."

Gu Yanchen comforted them: "Don't worry, check slowly."

As soon as the food was served, there was news in the group, and Shen Junci sent the results of the autopsy to the group.

"The deceased's cause of death was a ruptured heart and severe head injuries."

Qi Yi'an added a few photos to the autopsy report.

Bai Meng didn't look at the phone, and asked while eating: "Whose information is it?"

Gu Yanchen said: "The autopsy results from the forensic doctor." He looked at the roasted pig brains and fried kidneys on the table, and thoughtfully turned his phone around, "Let's look at it after dinner."

Everyone immediately understood, and tacitly pawed at the meal silently.
