Take the old attack to solve the case

The Xinghai apartment building is a 28-storey commercial and residential building. The lower three floors are shops and the upper ones are residences. Because the apartment was just handed over last month, the renovation inside is in full swing recently.

The deceased was a decoration worker named Cheng Shi. According to his colleagues, at around [-]:[-] p.m. the day before, Cheng Shi said he was not feeling well and left early.Seeing that Cheng Shi didn't come this morning, they called, but Cheng Shi didn't answer the phone.

Until today during the noon break, one of the workers called Cheng Shi again and heard Cheng Shi’s phone ringing from the elevator, but the elevator opened but no one was seen. Later they found that the phone ringing seemed to come from the top of the elevator. It was uploaded, so I felt something was wrong, I hurried to the management office to check the top of the elevator, and found that Cheng Shi was lying on the top of the elevator dead.

"It seems to have fallen to his death by accident." Chen Han's face was a little ugly. Just after eating, he saw this kind of bloody corpse, and his stomach problem began to come out again to find a sense of existence.

The reason for the elevator crash is usually that the elevator did not come up after the elevator door was opened, and the people waiting for the elevator may walk in without paying attention. This situation has happened frequently in recent years, especially many people like to wait for the elevator. When I was playing with my mobile phone, my eyes were fixed on the mobile phone. Out of the corner of my eye, I saw the elevator door open and walked in. I didn't pay attention to whether the elevator had already come up.

The top of the elevator is not flat, there are many protrusions, even if the elevator maintenance workers are not paying attention when walking on it, they can easily get injured, not to mention falling from a high place, which is basically fatal or injured.

Cheng Shi's cell phone fell beside him, and the screen was broken. Fortunately, the phone still rings, and the phone ring is very distinctive, otherwise Cheng Shi's body will not be found.

"Honey, answer the phone quickly, someone is calling, remember to miss me every day!"

The voice is not crisp, but very gentle, with a kind of expectation for relatives and lovers.

Listening to the ringtone from the phone, and thinking about the life that disappeared before the age of 30, everyone's heart was heavy.

On the surface, this should be an accidental fall, but the truth needs further investigation.

"Have you contacted the family of the deceased?" Zhang Zimu asked as he watched the forensic department carry the body away.

Cui Xiaoyu nodded, and said: "The decoration team has already contacted the family members before, but the family members are in H province, so they may not be able to come here for the time being."

Because judging from the situation at the scene, the deceased died of an accident. If an autopsy is to be performed, the consent of the family members is required, but the family members of the deceased cannot come in a short time.

Although the corpse was transported away, on-site inspection was still needed, and several decoration workers had to be questioned. The team did not close until after four o'clock in the afternoon. Pan Qingyue, who was in charge of the on-site inspection, moved the tools down first. Sun Liang checked the surroundings again before preparing to go back.

There are only two elevators in this apartment building, and now one of them has been blocked due to the crash, and there is only one elevator left. Zhang Zimu and the others talked about the case while waiting.

"Captain, there seems to be no problem with this case. It should be treated as an accidental fall." Chen Han looked at the number display on the elevator door. He was stuck on the sixth floor and did not move for a long time. This is the 21st floor, and it is a bit far to go down. Can only continue to wait helplessly.

Zhang Zimu didn't say a word. Judging from the scene, it is indeed possible to deal with an accidental fall. Now he only needs to wait for the elevator inspection report. If the elevator is found to be malfunctioning, the case can basically be closed, but he always feels a little bit uncomfortable.

Seeing that Zhang Zimu ignored him, Chen Han had no choice but to turn his head to look at Sun Liang. Seeing that he was looking at the inquiry record with a serious face, he couldn't help asking: "Sun Liang, what doubts have you found?"

"Well, it's a bit strange." Sun Liang pointed to a passage on the record and said, "Look at this paragraph."

……

Q: What was Cheng Shi doing before he left?

A: He is putting putty on the walls of the living room.

Q: What did Cheng Shi say when he asked for leave?

Answer: He said he had a cold, headache, sore throat, back pain, hand pain, etc. He also said that he was very dizzy and wanted to go back to sleep.

Q: What did Cheng Shi do at the time?How is your face?

A: I didn't pay attention to his face at the time, but he kept rubbing his head, neck and hands.

……

Chen Han stared at the record for a while, then suddenly frowned and said, "Hand?"

The main ingredients of putty are calcium carbonate and talcum powder. Long-term contact will make the skin dry and easy to crack. However, according to the information provided by the contractor, Cheng Shi has been a decoration worker for less than a year. For some moving jobs, this should not happen.

"Go back and test the putty samples brought back. Although it can't be dissected, some autopsies will be done first." Zhang Zimu said next to him.

Chen Han and Sun Liang nodded together.

At this moment, the elevator made a "ding" sound, and the mirrored door moved and opened to both sides. Sun Liang was standing at the door, talking and walking inside.

Sun Liang only felt that his feet were empty, and he fell forward.

The elevator didn't come up again!

"Sun Liang!" Both Zhang Zimu and Chen Han turned pale with shock, and hurriedly reached out to grab Sun Liang, but one of them was standing far away, and the other was holding something in his hand, even if they dropped it, it was too late.

"Ahhh..." Suddenly, there was a scream like a baby crying.

Sun Liang suddenly felt the belt tighten, as if someone pulled his belt from behind, and he was pulled by that force so that his whole body stopped in mid-air at a 45-degree tilt.

Zhang Zimu and Chen Han's hands paused in the air, and immediately grabbed Sun Liang's clothes and pulled him back.

The three of them looked at each other. Even though they were used to seeing life and death, they still broke out in a cold sweat when they encountered such a situation. Sun Liang felt that his legs were a little weak. If he hadn't supported the wall , I'm afraid I'm going to lie on the ground directly.

"Just now……"

"Just now……"

"Just now……"

The three of them spoke at the same time and stopped at the same time.

Zhang Zimu and Chen Han didn't know what to ask, but Sun Liang didn't know what to say.

Sun Liang recalled the baby cry he heard just now, and immediately remembered the piece of peach charm Li Jinrui gave him in the morning. It was like a piece of ice, which was obviously not the case before, which made him basically sure that it was the infant spirit who saved him just now.

Zhang Zimu thought for a while, and said, "We'll talk about this matter back to the team. Now let's get people to seal off this building, and thoroughly investigate what's going on with this elevator."

"Yes, Captain!"

……

It was exactly 24 hours from the time of Cheng Shi's death to Sun Liang's distress. In such a short period of time, the elevator had two problems in a row, one of which almost killed a policeman. Terrified, even if the police do not seal the building, these people dare not use the elevator.

Elevator maintenance personnel came as quickly as possible and checked the two elevators overnight, but it took time to conduct a comprehensive inspection.

……

"Sun Liang, why are you so unlucky lately?" Zhong Yiyan laughed at Sun Liang gloatingly, handed him a large bowl of soup, and said, "Just came out of the hospital and almost went in, are you the one who was in the previous period?" What bad things did time do, hahahaha..."

"What kind of strange soup is this?" Sun Liang smelled a sour and bitter taste, and quickly hid aside.

"The soothing soup that Aunt Fat made for you, hurry up and drink it." Zhong Yiyan smiled and put the bowl of dark soup on Sun Liang's table.

Fat Auntie's surname is Fei. Because she is chubby, everyone usually calls her Fat Auntie.She is the wife of the fat uncle in the cafeteria. They are both in their fifties and have no children. They usually treat the young people in the criminal police team as if they were their own children. When they heard that Sun Liang almost fell into the elevator shaft, he immediately made soothing soup. Give it to him, but I don't know what is used to make this soothing soup, it smells sour and bitter.

But at least it was someone's kindness, so Sun Liang could only pinch his nose and drink the soothing soup.

Seeing that it was almost time to get off work, the physical inspection side finally brought over the test report. There was no problem with the putty itself, but a kind of grease mixed with a large amount of toxic chemical substances was found on the hands of the deceased. The chemical substances in the exposure will not only damage the skin, but also cause dizziness, headache, disturbance of consciousness, and even respiratory failure and cardiac arrest in severe cases.

"I'm going to apply for a search of Cheng Shi's residence, and you are ready to go." Zhang Zimu said.

"Yes, Captain!"

……

The accommodation provided by the contractor was not far away. Four decorators lived in a room of more than ten square meters. After placing two iron beds, there was almost no place to turn around.

"Cheng Shi sleeps here, and the bed is all his stuff." A decorator pointed to the canopy bed by the window and said.

Zhang Zimu took a look, and saw that besides the bedding, there was a cardboard box with clothes at the foot of the upper bed. There were some toiletries and two tattered magazines on it. Zhang Zimu put it on. The gloves were checked, but nothing resembling grease was found.

"Has he got anything else?"

The decorator thought for a while, knelt down and pointed to a cardboard box under the bed, and said, "This seems to belong to him too."

"Like?" Zhang Zimu frowned slightly.

The decorator scratched his head and said: "The people in front left a lot of things when they left. We kept the useful ones and piled up the useless ones under the bed. But a few days ago I When I came back, I happened to see that Cheng Shi seemed to have pushed a box under the bed, so I thought it should belong to him."

The bottom of the iron frame bed is relatively high. Zhang Zimu took a look and saw that the bottom of the two beds was full of piles. He took a deep breath and called Pan Qingyue and the others in to search carefully, but he came out and patted his grandson. Bright shoulder, called him aside.

"Sun Liang, can you tell me what happened this afternoon?"

The author has something to say:

The story is written according to the timeline, so sometimes the follow-up of a case has the result in the later story.

The last case is that the people in the case will appear later, so I won't spoil it.
